Question
will a 3G SIM card work in a phone that dose not support 3G service.
A 3G SIM card will work in any GSM phone. They are backward compatible so if the phone doesn't have 3G capabilities, it will still work with a 3G SIM card. A 3G SIM just means that the SIM has the ability to work on the 3G network with a 3G phone, but it will also work on a non-3G network with a 2G phone. AT&T only provides 3G SIMs and they work in all their phones. I hope this helps. Thanks. DebiN
