Voice Roaming in the US is back!

It’s finally back! bmobile is proud to be the first local network to resume voice roaming in the United States of America.  Since the shutdown of the 3G networks in the US in February 2022, customers have been unable to make or receive voice calls while roaming there.  However, customers can once again make and receive voice calls via our 4G  Voice (VoLTE) roaming service.

With our 4G Voice roaming service, customers are expected to experience:

  • Superior audio quality (HD Voice) on calls made over the mobile network
  • Simultaneously use data while on a voice call (surf and talk)
  • Call conferencing with up to 6 participants
  • Quicker call set up time

*Subject to roaming partner network*

Effective 6th February 2023, bmobile launched its 4G roaming service in the US.  To access this service customers must have a VoLTE compatible device and would be required to visit bmobile to upgrade their sim card at no cost.

bmobile will roll out its 4G voice roaming in the US in phases. Apple/IOS users will be enrolled in phase 1 and all other mobile devices will be enrolled in subsequent phases.
