Carrying multiple phones for personal and business uses might be over for Verizon Wireless users. The company announced today that it is introducing an app that allows users to add up to four additional numbers to one smartphone.

The app is called My Numbers, and it can be downloaded from the Google Play Store or Apple’s App Store. It’s an additional $15 a month per number, but that’s significantly cheaper than purchasing a second, third, or even fourth phone. The app sets up separate voicemail and text messaging boxes for the different numbers as well.

There are other apps like Burner, Flyp, and Google Voice that have relieved some of the stress of the business and personal phones dilemma, but this is one of the first efforts from a major carrier. In 2016, T-Mobile launched a similar app called Digits that allowed customers to use up to five different phone numbers on their devices.

Traditionally, using multiple phone numbers in the US has been difficult. You would need multiple SIM cards in order to use different numbers, and most devices in the US don’t have more than one SIM slot.

You can download the My Numbers app starting today.
