While some things are better in pairs — like socks, earbuds, or scoops of ice cream — carrying two phones isn’t one of them. Wondering if you can have two phone numbers on one phone? Luckily, it’s possible — and the process is simpler than you might think.
We’ll guide you through the three simple steps to get a second line on your current mobile device, whether you’re looking for a second phone number for iPhone or Android. Then, we’ll dive deeper into how your second line will work.
How to get 2 phone numbers on one phone in 3 steps
The simplest way to get two phone numbers on one phone is by signing up for a VoIP service like OpenPhone. This allows you to access a VoIP phone number, which you can use to make and receive calls using an app on your mobile phone and computer.
Here’s how you can get two phone numbers on one phone with OpenPhone:
1. Create an OpenPhone account
Sign up for an OpenPhone account to receive a free seven-day trial and confirm that OpenPhone is a great fit for you. After entering your email address, you’ll receive a six-digit verification code via email to enter on the next screen.
2. Pick your phone number
We’ll automatically suggest a new number, but you can also tap Pick a different number to choose from any available US, Canadian, or toll-free number.
Verify your account with an existing phone number and enter your credit card information, and your account is all set! This will begin your seven-day free trial. Your card won’t be charged until the trial ends, and you can cancel at any time. We’ll even send you a heads up via email in case you change your mind.
3. Download the mobile app
Head to the App Store (iOS) or Google Play Store (Android) to download the OpenPhone app on your phone. Once you’re in, you can start using a new business line without needing a different phone.
Once you’ve downloaded OpenPhone’s VoIP app, your team have a BYOD policy, eliminating the need for work phones. Most importantly, you’ll have different phone numbers for your business and personal needs without needing an extra SIM or second phone.
Even after you add a business line to your cell phone, your personal phone number will still be tied to your device. Your business number will be connected to your VoIP account and WiFi, so you won’t incur extra charges from your carrier. If you have an Android or iPhone, the OpenPhone app can direct incoming calls for your business number straight to the phone you already own. (Yes, you can send and receive text messages, too.)
Bonus perk: Want to text and call from your computer? You can use OpenPhone’s web or desktop apps to make and receive phone calls. Plus, you can invite team members to your OpenPhone workspace to let them set up a second phone number on their phone.
Can I get more than 2 phone numbers on one phone?
Yes, with most VoIP systems, you can set up more than two phone numbers on one phone. OpenPhone allows you to add a second phone number to your existing device without needing a second SIM card or a dual-SIM phone.
Let’s look at a few more reasons you may need multiple phone numbers:
- Grow a local presence in different markets. For example, you can get a phone number that has one of New York City’s local area codes to call customers in New York City.
- Travel abroad hassle-free. VoIP numbers often have lower international calling and texting rates compared to traditional phone services.
- Have a backup phone number in case you encounter problems with one line, like having no network coverage in an area or poor call quality.
- Separate sales and customer support lines let customers connect directly with a rep who has the expertise to solve their issues.
With OpenPhone, you can easily switch between your numbers, set business hours, and customize the voicemail greeting for each number.
How does using a dual SIM phone work?
A dual SIM phone can give you two phone numbers using a physical SIM or an eSIM. A physical SIM goes inside your phone, while an eSIM is downloaded onto your device using an app.
Unlike VoIP phones, phones with dual SIM cards limit you to two numbers, which can affect your phone’s battery life and storage space, and you typically need to buy separate plans for each SIM card. Since only one mobile number can receive calls and messages at a time, you could miss important calls.
To use your second number with OpenPhone, all you need to do is launch OpenPhone’s mobile app. You won’t have to worry about switching back and forth between numbers or missing calls.
Scenarios when you may need 2 phone numbers on one phone
If you’re still on the fence about getting a second phone number, here are six scenarios when you may need to make the change:
1. You need to separate personal and business calls
If you can’t differentiate personal calls from business calls, you might greet customers in an unprofessional way. Plus, important business calls could get lost among personal messages, making it harder to stay organized.
2. You need to set better boundaries around work
If your customers call your personal phone number outside of business hours, it may be difficult to establish a work-life balance. A second number lets you set clear boundaries so you can unplug without worrying about missing important work calls.
3. Your team needs to collaborate on calls and texts
If your team can’t access the personal phone number that your business contacts call, they can’t work together to solve customer issues. With a secondary number, multiple team members can respond to calls and texts, improving customer support and efficiency.
4. You need to access complete conversation history
If you can’t see the entire conversation history between your company and customers, reviewing your daily interactions with your customers is difficult. A dedicated business line ensures all communication stays in one place, making it easier to track and reference past conversations.
5. You need to prioritize security
Sharing your personal mobile number for business can expose you to unwanted calls, spam, or security risks. A second number helps protect your privacy and keeps sensitive business communication separate from your personal life.
6. You don’t want to carry another phone
Carrying a separate phone for work is just plain annoying — one more thing to charge, keep track of, and lug around. With a second number on the same device, you get all the benefits of two lines without the extra bulk.
How do I know which number callers are trying to reach?
Business phone apps like OpenPhone make it easy to differentiate business calls from personal calls. The call screen for your VoIP number will look different from the one for your built-in phone app.
Plus, you’ll see a name displayed for business contacts saved on your VoIP address book. That way, you don’t risk answering your professional phone calls with a “Yo, what’s up?” or another unprofessional greeting.
If you have multiple phone numbers in your OpenPhone account, you can add a name and emoji to each inbox to keep on top of which number your callers are attempting to reach.
Want to avoid business calls when you’re not working? You can set up business hours and be confident that any after-hours calls you get are personal calls.
And if you’re on vacation, you can share access to your phone number and specific business contacts so your team members can handle your business calls. Your personal phone calls won’t be impacted.
How much does it cost to have 2 phone numbers on one phone?
A VoIP service can make a second phone number far more affordable than alternative options. Whereas buying a new cell phone or paying off your device to unlock it for dual SIM can cost several hundred dollars, VoIP services only charge a small monthly fee.
OpenPhone, for example, starts at $15 per user per month, with one free phone number included with every user.
As your small business grows and needs more advanced phone features, you can upgrade without spending hundreds on new phones for each team member.
How to set up a separate voicemail greeting
A professional voicemail greeting can help you avoid disgruntled clients when you miss calls. You can use your voicemail greeting to inform callers of your business hours, explain what information they should include in their voicemail messages, or provide a response time estimate.
Luckily, you won’t be stuck with the same voicemail greeting for your business and personal phone numbers. Once you’ve set your business hours in OpenPhone, you can add a voicemail greeting for both during and after business hours within the call flow builder, a visual way you can map out your call routing. For more information, check out our guide to setting up the call flow builder.
