I will be spending several months in England and would like to use my unlocked US based Galaxy S4 (gsm). My plan is to purchase a local sim card when I arrive in the UK. All phone specifications indicate that it should work. I plan to use the phone mostly for local calls, texting, and internet. I do not plan to us it to call back to the US. Will the unlocked Galaxy S4 (ATT) work? Do I have change any setting beyond purchasing a Sim card? Thanks in advance for your help.
