Question
I have an unlocked t-mobile t459 gravity but I use an AT%26T sim card. I can receive text messages and make phone calls but I can't receive picture or sound messages. I don't know how to fix this. Can you help?

Answer
Anytime that you use a SIM unlocked GSM device with another carrier, you have to manually program the WAP and MMS settings. Phone calls and text are automatic because they don't require any specific settings. You can contact AT&T to get the MMS and WAP settings (they are basically the same regardless of device and program these yourself). You can also check their web site and look up a phone that is similar to get them. I hope this helps. Thanks. DebiN
