I am new here. I am looking for an iPhone online but, want to know if a particular phone would work with GSM carriers outside US. Is there a proper way to find that? Specially the iPhones unlocked from US carriers.


If the Iphone is unlocked just trying with a difference SIM card from another carrier should be work without any problem.

  • That seems like quite the hassle if you don't already have another SIM card. – JMY1000 Nov 17 '17 at 6:59
