AT&T iphone to straight talk? - 1

Hi! I was wondering if I bought an iPhone off of the apple website, under AT&T service if after I bought the iPhone could I switch the SIM cards to one I got from Walmart's straight talk? Does my phone have to be unlocked? If so how do I unlock it? Has anyone ever done this?

I heard from a lot if people that AT&T and straight talk switched will work and you can go on the straight talk plan and I just wanted to be sure before I bought a phone I couldn't use. Thank you!

Added (1). I kind of don't want to buy an unlocked phone from the start, because they're at least $400 more.

Its better to buy unlocked iPhone straight from apple as it will work with any carrier that is gsm worldwide. But yes it should work.

Yes! You need to unlock your iPhone from your current network to switch to other networks.so, you can get unlocking service from your service provider / use unlocking software/use Remote unlocking servcie to unlock it.

  • 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.
