Hi wanted to check after Sprint unlock the phone and on contract completion/earlier contract completion, will Sprint Iphone 4s will work on AT&T or T mobile GSM network
Even unlocked, the SIM slot will not support a domestic carrier SIM; only overseas SIM cards will work.
the new SIM cards they use for iPhone 4 are a little smaller than the older ones. But my uncle just cut the extra parts of his old SIM card so it now fits the new smaller ones, and it just worked!
Will a Telmex GSM sim from mexico work? I keep on hearing overseas but there are International markets in the americas with GSM service.
To determne if a particular sim card will work for service outside the United States contact our international support team at l 888.226.7212
Look up Gevey sim for CDMA or R-SIM.... (you will need 5.0.1 and jailbreak or 5.1 and jailbreak)
