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.
