“Two is better than one” rings true for business phone numbers, but when it comes to your actual phone, one is more than enough. Getting a new landline means less desk space, while getting another cell phone means less room in your pocket or bag. Luckily, getting two phone numbers on one phone is possible — and the process is simpler than you might think.

We’ll guide you through the three simple steps you can take to get a second line on your current mobile device and then dive deeper into how your second line will work.

How to get 2 phone numbers on one phone in 3 steps

OpenPhone desktop and mobile app

The simplest way to get two phone numbers on one phone is by signing up for a VoIP phone service. This allows you to gain access to a VoIP phone number, which you can use to make and receive calls using an app on your mobile phone and computer. Your personal phone number will still be tied to your device, while your business number will be tied to your VoIP account, so you won’t incur extra charges from your carrier.

OpenPhone is a VoIP service that lets you create a second phone line — with a new number of your choice — without purchasing a new phone. Whether you have an Android or iPhone, the OpenPhone app can direct any incoming calls for your business number straight to the phone you already own. (Plus, you can send and receive text messages, too!) 

Here’s how you can get two phone numbers on one phone with OpenPhone:

1. Sign up for OpenPhone

Head to my.openphone.co/signup and enter your email address. You’ll receive a six-digit verification code via email to enter on the next screen.

2. Pick your phone number

Confirm whether you’ll be using your number for business or personal use. We’ll automatically assign you a new number, but if desired, you can tap “Pick a different number” to choose from any available U.S., Canadian, or toll-free number.

Verify your account with an existing phone number and enter your credit card information, then 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 (for iOS) or Google Play Store (for Android) to download the OpenPhone app on your phone. Once you’re in, you can start using your new business line without needing a different phone.

Bonus perk: When your computer is the most convenient device, you can also use OpenPhone’s web or desktop apps to make and receive phone calls. 🤩

Can I get more than 2 phone numbers on one phone?

With most VoIP systems, you can set up more than two phone numbers on one phone. For example, with OpenPhone, you get one free phone number per user with any plan. If you need more, you can add an unlimited amount of phone numbers for $5 per month each. Need separate lines for sales and customer support? You got it. No need to buy multiple work phones.

Compare this easy, flexible option to purchasing a physical dual SIM phone, which is a type of device that can also support two numbers. Unlike VoIP phones, phones with dual SIM cards limit you to two numbers only, and you typically need to buy separate plans from your carrier for each.

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 still see a name displayed for business contacts saved on your VoIP address book. You won’t risk answering your professional phone calls with a “Yo, what’s up?” or some other unprofessional greeting.

OpenPhone will also display text that says “OpenPhone Audio” alongside the OpenPhone app icon for your VoIP calls. If you have multiple phone numbers in your OpenPhone account, you can also add a name and emoji to each inbox to keep on top of which number your callers are attempting to reach. 🔥

OpenPhone receiving a phone call

Want to avoid business calls when you’re not working? You can set up business hours, so you can 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 so your team members can handle your business calls, and your personal phone calls won’t be impacted. 💯

How to set up a separate voicemail greeting

 OpenPhone app settings

Having 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 both your business and professional phone numbers. Here’s how easy it is to set up a voicemail greeting on OpenPhone’s web or desktop apps:

  1. Click “Settings” from the left-hand menu.
  2. Under “Workspace settings” select “Phone Numbers.”
  3. Select the phone number you want to create a voicemail message for.
  4. Scroll down to the Voicemail section and tap “Change.”
  5. Record your message, upload an audio file, or tap “Text to speech” to turn your voicemail script into a professional voiceover.

What will my outgoing caller ID look like?

It’s easy for your call recipients to differentiate between your phone numbers, too. In addition to displaying the phone number you’re using, many VoIP services allow you to set up a Caller ID Name (CNAM). With a CNAM, your name or business name will show up when you call from your second number.

Your outgoing caller ID can be up to 15 characters, including letters and spaces. You must be authorized to use your Caller ID Name, so there’s no pretending to be the government or a competitor. Leave your secret alter egos behind. 🦸

The only types of numbers that aren’t compatible with CNAMs are toll-free numbers. But since toll-free area codes (like 800, 888, or 877) are rarely used as personal numbers, your customers can safely assume they’re getting a business call.

How to set up caller ID with a VoIP service

The process to set up a caller ID can vary between VoIP services, but it’s usually a straightforward process that takes minimal effort. When you have an OpenPhone account, we’ll do most of the work for you. Fill out this one-minute form and you’re all set!

How much does it cost to have 2 phone numbers on one phone?

Not much GIF

Using a VoIP service can make a second phone number far more affordable than alternative options. Whereas buying a new cell phone or landline can cost you several hundred dollars, VoIP services charge a small monthly fee. OpenPhone, for example, starts at $10 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 of your team members.

Get separate numbers without separate phones

Calling or messaging your clients or team members from a personal phone number makes it difficult to maintain work-life balance. But getting two phones can be costly, not to mention impractical. With a VoIP service, you can get convenient access to a second line without a separate data plan or device. All you need is a mobile app and an internet connection to start using two phone numbers (or more) on one phone.

With OpenPhone, getting your second line only takes three steps, and setting up a custom caller ID only takes a minute. Get started with a free trial of OpenPhone today.
