CDMA Network Migration FAQs


(top)

I heard that my phone may not work beginning in January of 2022. What does that mean?

Boost Mobile has historically provided talk, text and data on the Sprint network. In June of 2020, we transitioned to the T-Mobile network as part of T-Mobile’s acquisition of Sprint. T-Mobile plans on shutting down existing Sprint cellular towers, which means customers who use phones that access the old Sprint network will no longer receive service.

If you’ve received a message from Boost Mobile asking you to upgrade, you may still be using the Sprint network. To take advantage of Boost Mobile’s Expanded Data Network, you’ll need to either upgrade your phone or switch to a new SIM card before the tower shutdown in January 2022.

How do I know which network I’m on?

To find out which network you’re on, log in to My Account and click “View Coverage” on your dashboard. If it opens the Nationwide map, you’re on the old Sprint network. If it opens the Expanded Data Network map, you’re on the new network.
