I arrive mid september from Australia and need to keep my Australian number but want a T-Mobile plan also. Was looking at the Samsung Galaxy S21 Ultra but it only has one sim slot and eSim? I think.
Does anyone know if I can use the esim for the t-mobile plan while keeping the actual sim slot for the Australian simcard? I read somewhere that the actual sim card may need to be the local t-mobile sim to allow the phone to access 5G?
