4G calling: Boost Mobile only enables 4G calling on approved phones, and we haven't confirmed this one.

User report (Mudita forum, 30 Jun 2025): calls and SMS worked on AT&T but AT&T blocked mobile data because the IMEI is not on its supported list; 'AT&T actively blocks the device's IMEI and there is no stable workaround.' Version not stated. Source

Boost Mobile runs on AT&T's network, so it uses AT&T's masts and bands.

About 2G: AT&T switched off 2G on 1 January 2017 and 3G on 22 February 2022.

About 4G calling: Boost checks phones with an IMEI tool and publishes no list.
