DIGITS allows you to use multiple mobile numbers on any compatible smartphone or device, as long as you’re connected to the internet. Proxy by DIGITS and DIGITS Talk & Text numbers are only accessible through the DIGITS app or web client and don't need a SIM card. And because they're powered by DIGITS, calls, voicemails, and texts stay separate from your main number in the DIGITS app. Check out the available DIGITS options.


Use your PROXY by DIGITS number anytime you don't want to give out your personal number. It helps you keep your personal number, personal. Limit one PROXY by DIGITS line per account. Included with your PROXY by DIGITS line is unlimited minutes and messaging, however, shortcode SMS messaging, like Uber's verification text or those from your banking institution for digital transactions, is not supported. Send calls directly to voicemail or avoid text messages by setting up the Do Not Disturb feature.

  1. In the DIGITS app, select Settings.
    • Android: Choose the menu icon in the upper left-hand corner.

DIGITS Talk & Text

DIGITS Talk & Text numbers allow you to use more than one number on the same device. Like all DIGITS numbers, calls, voicemails, and texts stay separate from your main number in the DIGITS app. Share your DIGITS Talk & Text line with up to 20 friends & family, by adding them in the DIGITS portal.
