A virtual cell phone number is a phone number that works on your cell phone without being tied to its SIM card. Instead of a second line from your carrier, the number lives in the network, and calls to it are delivered over the internet to an app on your phone.
That makes it the simplest way to get a second number: no second phone, no dual-SIM handset, no change of carrier. Digital Numbers offers it in the UK today and is bringing it to the United States.
How it works
- Choose your number and start a free trial.
- Install the Digital Numbers app on your iPhone or Android phone.
- Make and receive calls with your virtual number in the app. People you call see your virtual number, not your own.
You can also forward calls to any phone and change where they go at any time.
What you can use it for
- A business line that keeps customers off your personal number.
- Business hours: set hours for each day, and send calls to voicemail outside them.
- WhatsApp Business: register WhatsApp Business on your virtual number and keep personal WhatsApp on your own.
- A line per role: separate numbers for sales and support, or for a second business, all in one dashboard.

Common questions
What is a virtual cell phone number?
A phone number that works on your cell phone through an app rather than through your SIM card. Calls travel over the internet, so the number is not tied to your carrier or your handset.
Do I need a new phone or SIM?
No. The number works in the Digital Numbers app on the phone you already have.
Can I keep my virtual number if I change phones?
Yes. The number belongs to your account, so you sign in to the app on your new phone.
