    Hi everyone,

    I just bought a Tmobile Galaxy S4 and sim unlocked it. I'm trying to activate it on Straight Talk, and purchased one of the original ATT sims. I read that someone was getting 4g speeds on an ATT Sim using this same setup on an S3. Here's my thoughts and problem....

    1.) I can't get or seem to find the correct APN settings. Googled and youtubed several, nothing seemed to work. Tried restarting after each attempt to no avail.

    2.) I'm starting to wonder....even though it's sim unlocked can I use the ATT sim and it's just a matter of getting the right APN settings?

    Right now I can make calls, send / receive texts, but can't get the internet to work let alone try and get the best speeds

    Any thoughts? Help appreciated!!

    Try calling customer service and see if they can switch your IMEI?
