At the moment, you can’t roam or make international calls on any of the SMARTY plans… but we’re working on it. 

Also, we currently don’t support Supervoice (VoLTE) or WiFi calling. Again, we’re hoping to offer these services in the near future. 

Data and texts will work over 3G (2100 MHz), 4G (1800 MHz) and 4G (800 MHz). Voice calls will only work over 3G.
