How to fix an iPhone 4S in straight talk?

I'm on the BYOP so I bought a SIM card from straight talk for my AT&T iPhone 4S. But I can't get my picture messaging to work I send them or receive them unless its from an iPhone. Can someone please help me!

You need to reprogram the MMS settings and APN settings in the Iphone so that it was use Straight Talk's Text APN server and not ATT's… This is why you can't send/receive MMS… It only works for Iphones cause Iphone-2-iphone is Imessage… Not a normal MMS… LMAO

Call ATT… Get the MMS and APN setting information… Or simple google it… Then reprogram the iphone in settings.

for future googlers to the question--- Again… I say AGAIN… You mix branded phones and their carriers… Some things are bound to be slow or won't work at all… Facts of life, regardless of phone and wireless carrier.

  • Virgin Mobile iphone or Straight talk iphone? I heard lots of negative reivews on Straight talk iphone and that if youre planning to get a straight talk, you should get a android instead. I seen lots of reviews how their iphone can't connect to the data/really slow and have bad customer service. Although they offer a good unlimited plan, which carriers should i choose to get the iphone? Virgin mobile or Straight talk? I'm planning to buy full price iphone 5 in walmart

  • Unlocking iPhone 3G to Straight Talk? I've been trying to do this for free for a while. I have a SIM card that would work. I just tried unlocking it through UltraSn0w and it says Searching for a while and eventually no service. I've already jailbroken it. There should be service here as I get it on my other phone. How do I get this to work? I'm trying to use the SIM card from my current phone. Not one I just ordered.
