    I have a Microsoft lumia 640. T-mobile is unlock. I set my SIM with straight talk I can get calls and text but I can't get internet or MMS. I need to set up my APN but straight talk couldn't help me. Does anyone know how to set it up with straight talk. Please and thank you.

    Straight talk uses all the major carriers. May I assume you are running an AT&T flavor SIM since you unlocked from T-Mo?
