LinkedIn X [Back to blog](https://skipcall.io/en/blog) Business phone Published 11 November 2026 # Business Number on a Personal Phone: 4 Ways to Run Two Numbers on One Phone Dual SIM, eSIM, a carrier add-on or a business phone app: four ways to put a business number on your personal phone. What each one really separates (calls, texts, voicemail, contacts, hours, the bill), the iPhone and Android settings, and what happens to the number the day you leave the company. 4 ways to run two numbers on one phone: physical dual SIM, eSIM, a carrier second-number add-on, a business phone app 7 things to keep apart between work and private life: calls, texts, voicemail, contacts, hours, the bill and who owns the number 1 cellular data network at a time on an iPhone with two lines, per Apple's Dual SIM support page (read November 11, 2026) To put a business number on a personal phone, you have four options: a second SIM card, an eSIM, a second-number add-on from your carrier, or a business phone app that carries the work number. The first two add a cellular line to the phone. Only the app also separates contacts, working hours and ownership of the number, which stays with the company. You are probably in one of these situations. A You work for yourself and customers call your personal cell, Sundays included. You want a number to hand out, and a switch to turn it off. B You are an employee and you have been asked to use your own phone for work. You do not want two devices in your pocket, or customers in your private contacts. C You run a team. Your reps call from their cell phones, and when one of them leaves, customers keep calling that person. ## Can you have two phone numbers on one phone? Yes, and it has been possible for years. What changed is how. Ten years ago you needed a phone with two SIM trays. Today most recent smartphones take a physical card plus an eSIM, and an app is enough to add a third number if you need one. Apple’s support page lists Dual SIM as available on “an iPhone XS, iPhone XS Max, iPhone XR, or later,” and adds that “iPhone 13 models and later also support Dual SIM with two eSIMs.” On the Google side, Pixel help says dual SIM (a physical SIM plus an eSIM) works on Pixel 3a and later, that two eSIM profiles at once need a Pixel 7 or newer, and that in the US, Pixel 10 and later models, the Pixel 10 Pro Fold excepted, are eSIM only. The four options are not equal. They do not answer the same question: the first two add a line, the third adds a number, the fourth adds a work tool. Two numbers, one phone: what each option really separates Physical dual SIM Two cards, two plans - Calls Separate - Texts Separate - Voicemail Separate - Contacts Partly - Hours Partly - Bill Separate - Number ownership Partly eSIM One card plus one digital line - Calls Separate - Texts Separate - Voicemail Separate - Contacts Partly - Hours Partly - Bill Separate - Number ownership Partly Carrier add-on A second number on the same line - Calls Partly - Texts Partly - Voicemail Partly - Contacts Not separate - Hours Partly - Bill Not separate - Number ownership Not separate Business phone app The work number lives in an app - Calls Separate - Texts Separate - Voicemail Separate - Contacts Separate - Hours Separate - Bill Separate - Number ownership Separate How to read it: the most common state for each option. “Partly” means the separation depends on a manual setting, on the carrier or on the plan you pick. > Adding a number takes ten minutes. What matters is what stays mixed once the number is added: the contact list, the hours, the bill, and the question of who the number belongs to. ## Physical dual SIM: how does it work? This is the oldest option. The phone has two slots, you insert two SIM cards, each with its own plan and number. The phone shows two signal indicators and either asks which line to use for each outgoing call or applies the default you picked. **What it separates well.** Calls, texts and voicemail: each line has its own. The bill too, since there are two plans, which makes an expense claim simple. **What it leaves mixed.** There is one contact list: customers and friends sit side by side. One call log as well, even if it shows the line. And turning the work line off at night is manual, in settings. Two practical limits. First, hardware: phones with two physical trays have become rare at the high end, and Apple says only certain iPhone models sold in Hong Kong and Macao take two nano-SIM cards. Second, ownership: if you buy the second plan in your own name, the number is yours. That is comfortable for a freelancer and a problem for a company, as we will see below. ## eSIM: a second number without a second card? An eSIM is a SIM soldered into the phone that the carrier activates remotely. In use it is dual SIM: two lines, two numbers, two plans. You keep your current line for personal use and add the work line as an eSIM, or the other way around. Here is what Apple says about running two lines, which is worth reading before you commit: 1. 01 #### Both numbers call and receive. Both lines can make and receive voice and FaceTime calls, and send and receive iMessage, SMS and MMS. 2. 02 #### Only one line carries data. Apple puts it this way: “Your iPhone can use one cellular data network at a time.” You choose which. 3. 03 #### A call in progress can send the other line to voicemail. If you are already on a call, an incoming call to your other number goes to voicemail, unless Allow Cellular Data Switching is on and the other line’s carrier supports Wi-Fi Calling. 4. 04 #### Corporate plans do not always support it. Apple notes that if you have an enterprise or corporate cellular plan, you should check with your company administrator whether the feature is supported. Pixels follow the same logic. Google’s help says that on Pixel 8, 8 Pro and earlier, an incoming call on the other SIM during a call is sent to voicemail. From Pixel 8a on, the first call can be put on hold, provided mobile data is on for both SIMs and the second SIM’s carrier supports Wi-Fi calling. ## Is a carrier second-number add-on worth it? Some carriers sell a second number tied to your existing line, with no second card. Availability, price and what is included change from carrier to carrier and from plan to plan: the add-on list in your carrier account shows whether yours offers one, and at what price. Do not confuse this with adding a watch or tablet to your plan. Those share your existing number across devices. They do not create a second number. **Why people choose it.** One contract, one bill, nothing to install on the SIM side. For occasional use, such as a number to put on a listing, it is the fastest route. **Where it stops.** Everything depends on the plan: texting included or not, separate voicemail or not, schedulable hours or not. The bill stays single, so a company cannot carry it, and the number is tied to your personal contract. For lasting business use it is the least clean of the four: it adds a number and separates almost nothing. ## Business phone app: how does a work number live in an app? Here the number no longer lives on a SIM card. It is assigned to an account, and calls travel over the internet, on Wi-Fi or on the data from your personal plan (how that works is explained in our [VoIP vs. WebRTC](https://skipcall.io/en/blog/voip-vs-webrtc) comparison). You install the app, sign in, and the number rings inside the app. This is often called a [virtual business phone number](https://skipcall.io/en/blog/virtual-business-phone-number), covered in its own guide, along with the steps to [get a virtual phone number in five minutes](https://skipcall.io/en/blog/how-to-get-a-virtual-phone-number). Two families of apps exist, and they do not serve the same need. 1 **Second-number apps for individuals and freelancers.** They give you a number, calls and texts. Google’s help describes its own service in one line: “Google Voice gives you a phone number for calls, texts, and voicemails.” What it includes for a business, and where it stops, is in our article on [Google Voice for business](https://skipcall.io/en/blog/google-voice-for-business). 2 **Business phone apps.** The account belongs to the company, which assigns a number to each person. Depending on the tool you also get call recording, transcripts, a link to the CRM and reporting. This is Skipcall’s family, with a phone plan from $25 per user per month billed annually. What the app changes compared with a second cellular line comes down to four points: - **The contact list is separate.** Work contacts live in the app or in the CRM, not in your personal address book. - **Hours can be set.** You close the app, or schedule a window, and calls go to the work voicemail without touching your private line. - **The number follows the account, not the phone.** Change devices, sign in again, and the number is there. It also rings on the computer. - **The company keeps the number.** When someone leaves, the number is reassigned to the next person. The trade-off is well known: quality depends on the connection. A call on weak LTE or a crowded Wi-Fi network sounds like it. The free [VoIP speed test](https://skipcall.io/en/tools/voip-speed-test) measures your connection in a minute, and the guide to [VoIP call quality problems](https://skipcall.io/en/blog/voip-call-quality-problems) ties each symptom (choppy audio, echo, dropped calls) to its cause. If you mostly call from home, the guide to a [phone system for remote teams](https://skipcall.io/en/blog/remote-team-phone-system) covers equipment and home networks, and the article on [what a softphone is](https://skipcall.io/en/blog/what-is-a-softphone) explains how app-based calling works. ## What does each option really separate? Here is the comparison, criterion by criterion. “Depends on the plan” means the answer changes from one carrier or vendor to the next: it is a question to ask before you pay. | What to keep apart | Dual SIM or eSIM | Carrier add-on | Business phone app | | - | - | - | - | | Calls | Yes, one line per number | Depends on the plan | Yes, inside the app | | Texts | Yes, one line per number | Depends on the plan | Yes if the plan includes texting | | Voicemail | Yes, one per line | Depends on the plan | Yes, with its own greeting | | Contacts | No, one contact list, with a default line per contact | No | Yes, in the app or the CRM | | Ringing hours | Manual: turn the line off or silence it | Depends on the plan | Yes, set or scheduled | | The bill | Yes, two plans | No, a single bill | Yes, a subscription paid by the company | | Who owns the number | The plan's account holder, often you | You | The account holder, usually the company | Two ways to read this table. If you work alone and the number is yours, an eSIM does the job for the price of a plan. If the number has to outlive the person using it, only the last column answers. And if the question is less “two numbers for one person” than “several numbers for a small team,” the guide to a [multi-line phone system for a small business](https://skipcall.io/en/blog/multi-line-phone-system-small-business) starts from that need. ## How do you set up two lines on an iPhone? The steps below follow Apple’s support page on Dual SIM with an eSIM. Labels may vary slightly with your iOS version. 1. 01 #### Label your lines. After the second plan is activated, label each one. Apple’s own example is to label one plan “Business” and the other “Personal.” To change it later: Settings, Cellular, the number, then “Cellular Plan Label.” 2. 02 #### Choose your default line. It is the number used for calls or messages to people who are not in Contacts. Pick the personal line if you mostly call family and friends, the business line if the phone is mainly for work. 3. 03 #### Choose the line for cellular data. One at a time. Use the plan with more data, or the one the company reimburses. 4. 04 #### Assign a line to your key contacts. Open the contact, tap the word “default,” and pick the number. With no setting, the iPhone reuses the line you last used with that contact. 5. 05 #### Set iMessage and FaceTime. You can attach one line or both. If you do not want a customer to message your personal number over iMessage, check this setting. 6. 06 #### Check the line before every sensitive call. On the keypad, enter the number, tap the number shown at the top of the screen, then choose the line. In Messages, tap the number at the top of the conversation to switch lines. To silence the work line during set hours, the iPhone User Guide describes Focus and how to allow or silence notifications for it. We do not walk through those screens here: they change from one iOS version to the next, and [Apple’s guide](https://support.apple.com/guide/iphone/set-up-a-focus-iphd6288a67f/ios) is the reference. ## How do you set up two lines on Android? Menus vary by brand. The steps below are those Google describes for Pixel phones; on a Samsung or a Motorola the labels are close. 1. 01 #### Open SIM settings. Settings, Network and internet, then SIMs. The primary SIM section lists three choices: calls, messages, mobile data. 2. 02 #### Choose the SIM for calls, or be asked every time. The “ask every time” option shows the line choice before each call. It is the safest setting for the first few weeks. 3. 03 #### Choose the SIM for messages. A confirmation text sent to a customer from the personal number is the most common mistake. Set this before the first one goes out. 4. 04 #### Choose the SIM for data. Only one SIM can be the default for mobile data. 5. 05 #### Turn the work line off when you are not working. Settings, Network and internet, Mobile network, the SIM in question, then turn off “Use this SIM.” Calls go to that line’s voicemail. Android has one more asset when the employer provides apps: the **work profile**. According to Google’s help, it lets you separate your work apps and data from your personal apps and data. The organization manages the work apps and data; your personal apps, data and usage stay private. When work app icons are grayed out, the profile is paused: that is the setting to know for evenings and time off. ## How do you turn the work number off at night and on weekends? This is often the real reason for wanting two numbers. A separate number is not enough: you also need an easy way to silence it, and a greeting that says when you will answer. 1 **Turn the line off.** With dual SIM or an eSIM, you switch the work line off in settings. It is radical, and manual: you have to remember to turn it back on Monday. 2 **Silence the phone.** Focus on iPhone, Do Not Disturb on Android. Careful: depending on your settings, this silences your personal calls too. 3 **Set hours in the app.** The business number goes to its voicemail outside the hours you choose. Your personal line is untouched. On Android, Google’s help describes what Do Not Disturb can do, and it is finer than plain silence. A mode’s notification filters include a People setting, to block or allow calls, messages or conversations, and an Apps setting, to choose which apps can still notify you. An option to allow repeat callers lets someone through if they call twice within 15 minutes: useful for a family emergency, awkward if a customer insists. The mode can turn on automatically on a schedule. One practical consequence for a phone app: if you silence the whole phone, make sure the work app is not on the exception list, or it will ring anyway. In all three cases, record a voicemail greeting that states your hours and another way to reach you in an emergency. Ready-to-adapt wording is in our [voicemail greeting scripts](https://skipcall.io/en/blog/voicemail-greeting-scripts), and the [voicemail script generator](https://skipcall.io/en/tools/voicemail-script-generator) writes one from your hours. If you are an employee, the question goes beyond a phone setting: it touches how work is organized and what your company’s policies say. We cover it in a separate guide to the [right to disconnect and the work phone](https://skipcall.io/en/blog/right-to-disconnect-work-phone). ## Who owns the number when you leave the company? The account holder. It is the point everyone looks at too late. Three situations follow. A **The line or the account is in the company’s name.** The number stays. A departing employee takes it only if the company agrees to release it. B **The line is in the employee’s name and expensed.** The number is theirs. Customers who saved it will keep calling it after the person has left. C **You work for yourself.** The number is yours either way. Just pick an option you can leave while keeping the number. Moving a number from one provider to another is called porting, and it is the account holder who requests it. The steps, the documents and the usual delays are in our guide to [business phone number porting](https://skipcall.io/en/blog/business-phone-number-porting), and the free [number porting checklist by country](https://skipcall.io/en/tools/number-porting-checklist-by-country) lists what to prepare. ## Who pays, and how is personal use treated? Three setups exist: the company pays for the line or the app, the employee pays and is reimbursed, or the company provides the whole phone. Each has its own tax and payroll consequences, and they differ depending on whether personal use is allowed. In the US, the IRS addressed this in Notice 2011-72 and a companion memo to examiners. Its 2011 announcement says that when an employer provides a cell phone “primarily for noncompensatory business reasons,” the business and personal use of the phone is “generally nontaxable to the employee,” and that the IRS will not require recordkeeping of business use to receive this treatment. It also says employers that require employees, for those same reasons, to use their personal phones may treat reimbursements for “reasonable cell phone coverage as nontaxable,” which does not extend to “unusual or excessive expenses” or to reimbursements made “as a substitute for a portion of the employee’s regular wages.” Some states also have their own rules on reimbursing employees for work use of a personal phone. This is an archived 2011 release, quoted here as a starting point. It is general information, not tax or legal advice: check the current guidance with your accountant. What you can do without waiting: - **Write the rule down.** One line in the device policy or the offer letter: which number is for work, who pays for what, whether personal use of the work tool is allowed. - **Split the bills.** A separate invoice for the business number avoids any allocation math. - **Keep proof of use.** A business phone app gives a record of work calls without exposing private ones. ## What are the security risks of a work number on a personal phone? A personal phone is not managed by the company. It has its own apps, its own passwords, and sometimes no passcode. Four precautions cover most of it. 1. 01 #### Lock the device. A passcode or biometrics on the phone is the minimum before it receives customer calls and verification texts. 2. 02 #### Plan for departure and loss. With an app, the company signs the session out remotely and the number is no longer on the device. With an eSIM, Google says a Pixel can require a password before an eSIM is erased, in its security settings. 3. 03 #### Know where recordings go. If calls are recorded, they should be stored in the company’s tool, not on the phone. Consent rules vary by state; they are covered in our article on [call recording laws for businesses](https://skipcall.io/en/blog/call-recording-laws-business). 4. 04 #### Protect the account, not just the device. A password unique to the app and two-factor authentication where it is offered. Fraud that targets business lines is covered in our guide to [VoIP security and toll fraud](https://skipcall.io/en/blog/voip-security-toll-fraud). ## How much does a second number on your phone cost? The cost depends less on the technology than on what you expect from the number. $25 per user per month: Skipcall's phone plan billed annually, with recording, transcripts and AI summaries included $70 per user per month: Skipcall Starter billed annually, the first plan with the power dialer and the 4-line parallel dialer 2 plans to pay for with dual SIM or an eSIM: the price of the second plan comes on top of the first The price of a second cellular plan varies too much from one carrier to another to quote here: compare your carrier’s price with these reference points. And count what appears on no invoice: the time spent looking for a call across two logs, or the customer lost because their number sat in a former employee’s phone. ## Which option fits your situation? **Freelancer, few calls.** An eSIM with a small plan, or a second-number app. The number is yours and you turn it off at night. Enough as long as you do not need to record or share calls. **Employee asked to use a personal phone.** Ask for an app in the company’s name instead of a line in yours. You keep one device, your private contacts stay private, and the number is not your problem if you leave. **Founder or owner.** Your personal number is already out there. Take a business number in the company’s name for everything public (website, signature, cards), and keep the personal one for family and a few chosen contacts. **Sales or support team.** A business phone app, one number per person, in the company’s name. It is the only option where a departure does not cost customers. To compare offers, see our guide to the [best VoIP for sales teams](https://skipcall.io/en/blog/best-voip-for-sales-teams) and, if the team prospects, the one on [best telesales software](https://skipcall.io/en/blog/best-telesales-software). Not sure whether to show a local or a toll-free number? The free [local vs. toll-free number tool](https://skipcall.io/en/tools/local-vs-toll-free-number) asks the questions in order. And if you call prospects, first read what a [direct dial, a mobile or a switchboard number](https://skipcall.io/en/blog/direct-dial-vs-mobile-vs-switchboard) changes, and the rules on [cold calling cell phones](https://skipcall.io/en/blog/cold-calling-cell-phones). ## What should you ask before you choose? Whether you are talking to a carrier, an app vendor or your employer, these eight questions prevent bad surprises. Copy them as they are. 1. 01 #### Whose name is the number in? Is the contract in the person’s name or the company’s, and who can request a port? 2. 02 #### Can I leave with the number? Can it be ported to another provider, and how long does it take? 3. 03 #### Is texting included, both ways? Some numbers receive verification codes, others do not. Ask about the number type you are buying. 4. 04 #### Is voicemail separate? With its own greeting, and a notification distinct from the personal line’s. 5. 05 #### Can hours be scheduled? Ringing windows by day of the week, or just an on-off switch? 6. 06 #### What happens on a second incoming call? A tone, a hold or voicemail: the answer depends on the phone, the carrier and the app. 7. 07 #### What does a call use? For an app, how much mobile data per minute, and what happens on a weak connection? 8. 08 #### What is the full price? Subscription, number, overage minutes, international calls, contract length. ## What do you do with the old number everyone already has? Nobody asks this when they create the business number. If customers have had your personal number for years, they will keep using it. 1 **Announce the change.** A short message to your work contacts, with the email signature and voicemail greeting updated the same day. 2 **Call back from the new number.** Every time a customer calls the old one, call back from the business number. Within a few weeks it is the one at the top of their list. 3 **Set a date.** Pick the day after which you no longer answer customer calls on the personal number, and hold to it. If you would rather have calls follow from one number to the other during the transition, our guide to [call forwarding vs. call transfer](https://skipcall.io/en/blog/call-forwarding-vs-call-transfer) explains the settings on cell phones, landlines and VoIP. ## Three templates to copy on switch day A new number changes nobody’s habits until it is announced. Here are three short texts to adapt: one for customers, one for voicemail, one for the internal rule. 01 #### The message to your customers Text or email “Hi, this is \[first name] from \[company]. I now have a business number: \[number]. Please save it in place of the old one. It is the number I answer on weekdays, 9 a.m. to 6 p.m. Talk soon.” 02 #### The voicemail greeting on the business number 15 seconds “Hi, you have reached \[first and last name] at \[company]. I answer Monday through Friday, 9 a.m. to 6 p.m. Leave your name, your number and the reason for your call, and I will call you back the same day.” 03 #### The line to add to the policy or the offer letter Internal rule “The number \[number] is assigned to \[first and last name] for work. It belongs to \[company] and returns to the company if the employee leaves. Conversations with customers go through this number, not through the employee’s personal number.” Write the number in international format, with +1 in front, in your signature and on your website: a customer abroad can then call you back in one tap. ## One phone or two? The question comes up every time, and it deserves a straight answer: a second device is still the most radical separation. It goes in a drawer on Friday evening. It also has a price, the device and the plan, and a practical flaw: two phones to charge, carry and not forget. **One phone is enough** when the business number lives in an app or on an eSIM, when you can turn it off in one move and when the number is in the right name. That covers most freelancers and sales reps. **Two phones make sense** when the company requires a device it fully manages, when you handle sensitive data, or when you know you will not hold the line with a single screen. ## How do you set up a business number in one hour? 1. 01 #### Decide who will own the number. You or the company. That answer already rules out one or two options. 2. 02 #### List what you want to keep apart. Go through the seven rows of the table and tick the ones that matter to you. 3. 03 #### Activate the line or install the app. An eSIM is activated with the carrier; an app is set up in a few minutes. 4. 04 #### Label, set the default line, choose the line for texts. These three settings keep you from calling a customer from the wrong number. 5. 05 #### Record the business voicemail greeting. Name, company, hours, another way to reach you. 6. 06 #### Set your hours. A ringing window, or a calendar reminder to turn the line off. 7. 07 #### Test the three cases. An incoming call during a call on the other number, an outgoing text, a call received after hours. 8. 08 #### Publish the new number. Email signature, website, business listing, cards. And tell current customers which number to use from now on. ## What mistakes should you avoid with two numbers on one phone? **Answering “hello” without knowing which line is ringing.** Line labels show on screen: read them, and answer the business line with your name and the company’s. **Calling a customer back from the personal number.** Once the personal number is in their phone, they will use it. Set a default line per contact. **Leaving the number in an employee’s name.** Convenient on the day you sign up, expensive on the day they leave. **Forgetting voicemail.** A personal greeting on a business number, or no greeting at all, costs you callbacks. **Using a consumer number for volume calling.** A number that places many outbound calls can get flagged. Causes and fixes are in our article on a [caller ID marked as spam](https://skipcall.io/en/blog/caller-id-marked-spam). **Assuming every setup works abroad.** Carrier add-ons and consumer apps are often tied to one country. Check coverage before a trip or a hire in another country, and save customer numbers with their country code, as shown in our list of [international dialing codes](https://skipcall.io/en/blog/international-dialing-codes). ## Where Skipcall fits, and where it does not Skipcall is a business phone app: each user has a business number, used from [the mobile app](https://skipcall.io/en/features/application-mobile) and from the browser. The account and the numbers are in the company’s name. Calls, texts, recording, transcripts and AI summaries are included from the [business VoIP plan](https://skipcall.io/en/business-voip), from $25 per user per month billed annually; the dialing modes for prospecting start with the Starter plan, from $70 per month. Calls are logged in HubSpot, Pipedrive, Salesforce or Attio through native integrations. Three things to know, so the choice is clear: - **Porting is on the way.** Skipcall will soon let you port your existing numbers. Until then, you start with a new number, and the method described above for the old number moves your customers over. - **No phone system for reception.** No phone menu, no call queues, no inbound routing between departments. - **Not a tool for individuals.** For a simple second personal number, an eSIM or a consumer app costs less and is enough. ## Key takeaways - Getting **two numbers on one phone** is easy; the real subject is what stays mixed afterwards. - **Dual SIM and eSIM** separate calls, texts and the bill, not contacts or hours. - **A carrier add-on** adds a number and separates almost nothing. - **A business phone app** separates everything, ownership of the number included, at the cost of depending on the connection. - **The number belongs to the account holder**: decide that on day one, not on the day someone leaves. - **Test three cases** before you publish the number: a second incoming call, an outgoing text, a call after hours.

A second SIM card in a dual-SIM phone, an eSIM added next to your current card, a second-number add-on sold by some carriers, or a business phone app that carries the work number. The first two add a real cellular line to the phone. The app is the only option that also separates contacts, working hours and ownership: the number belongs to the company account and stays there if you leave. **Can you have two phone numbers on one phone?** Yes. Apple's support page says Dual SIM with an eSIM works on an iPhone XS, iPhone XS Max, iPhone XR, or later, and Google's help says Pixel 3a and later support a physical SIM plus an eSIM, both read on November 11, 2026. Both numbers can make and receive calls and send texts; only one line carries cellular data at a time. A business phone app adds another number without touching the SIM cards. **What is the difference between dual SIM and eSIM?** None in daily use: either way the phone runs two cellular lines. The difference is hardware. Physical dual SIM needs two card slots, which are rare on recent phones sold in the US. An eSIM is a SIM built into the phone that the carrier activates remotely, so you keep your current line and add the second one without inserting anything. **Do I need a second phone plan for a second number?** With dual SIM or eSIM, yes: each line has its own plan and its own bill. With a business phone app, no: calls travel over the internet (Wi-Fi or the data on your existing plan) and you pay a subscription to the app. As a reference point, Skipcall's phone plan starts from $25 per user per month billed annually, with call recording, transcripts and AI summaries included. **Who owns the business number if I leave the company?** Whoever holds the account. If the company bought the line or the app subscription, the number stays with the company and is reassigned to your replacement. If you bought the line in your own name and expensed it, the number is yours and your customers leave with it. Decide this on day one and write it down, because it is the hardest thing to fix later. **How do I stop work calls in the evening and on weekends?** Three levels, from simplest to cleanest. Turn the work line off in the phone's settings when the day ends. Use a Focus on iPhone or Do Not Disturb on Android to silence calls during set hours. Or set business hours inside the phone app, which then sends calls to the work voicemail and leaves your personal line alone. In every case, record a voicemail greeting that states your hours. **Can my employer see my personal calls if I install a work phone app?** A business phone app only sees the calls made and received inside that app, not the ones on your personal line. On Android, a work profile goes further and separates work apps and data from personal ones: according to Google's help, your organization manages your work apps and data, while your personal apps, data and usage stay private. Ask your employer exactly what is being installed, and whether it manages the whole device or only a profile. **Does Skipcall let me use a business number on my personal phone?** Yes. Each user gets a business number used from the mobile app (iOS and Android) and from the browser, on a personal phone or not. Calls, texts, recording, transcripts and AI summaries are included from the phone plan, from $25 per user per month billed annually. Skipcall will soon let you port your existing numbers; until then, you start with a new number. Skipcall has no phone menu or inbound call routing between departments. ## A calendar full of meetings starts with a call.
