Hello i have switched my phone plan to 5g , it was 3g before. Ever since i have changed it early this morning because i am now in the us, before canada and now i still have no service.
@Maria33 Do you have a Canada-US plan or a US roaming add-on? If so, what phone do you have? If it is not a VoLTE enabled phone you will only be able to use T-Mobile's 2G network for voice calls.
