Can unlocked cell phones call another country?
HI i think unlocked cellphone wont cause any problem while making call to any countries.Usually unlocked cellphone is nothing but phone is free to any GSM sim in any countries .If your phone is unlocked then you can freely use it on any countries with any sim and call anywhere .Else if your phone is locked to network provider .Then unless you unlock it you can’t use it on other GSM sim.If you are in need to unlock your phone .Then visit sites like SimpleUnlocking.com who render code for all mobile models at affordable cost .
I think it does not matter if your cellphone is unlocked whenever you make a call even of it’s within or outside the country. It is the sim card and the service provider that matters whenever you call. Make sure that your cell phone can handle the sim card of the service provider that you wish to make use. And as long as the provider has an available service for the country that you wish to call, then you can go ahead and start making calls.
