Also, just to reiterate, this service is for CALLING phone numbers in the countries listed. It has nothing to do with the SIM. the SIM is for DATA only and works in all supported countries without the need for this addon (meaning you get DATA connection). You can also make calls to USA & Canada from ANY country in the world as long as you have a data connection (mobile or Wifi), without the need for any addons (all you need is the Freedompop App and a data connection).
