Iphone 4s bought in england. Came to Colombia and i tried to use the phone with a Colombian sim but doesnt work. what should i do?
I started off using it with t-mobile, in england, and now here if i try to use it with a different sim it doesnt work. I've been told that it may be a problem with Apple compatibility. How can i work it out?
iPhone 4S, iOS 6.0.1
