SIMBA has just updated their list of roaming partners. If you are roaming in the States, you can now choose to connect to Verizon which supports both VoLTE and 5G. That means you can use the dialer direct without needing to SIMBA Voice App to make and receive voice calls. 5G Roaming is also available on AT&T.

To get roaming working, you will need a phone that supports the following bands (if not all) to roam on LTE or 5G. Most of the mid range to high end smartphones from Apple or Samsung should support these bands. Please check your phone specifications to ensure compatibility.

LTE bands:

  • 2
  • 4
  • 5
  • 12
  • 13
  • 14
  • 66

5G bands:

  • 66
  • 70
  • 71

If you are roaming on T-mobile or AT&T, you will need to use the SIMBA voice app to make and receive calls.
