What carriers can i connect an iphone 4 CDMA to?

I bought a bad ESN sprint iphone 4 ios 6 planning to unlock it and connecting it with t mobile with a micro sim card but when I got it it was a CDMA and so it doesn't have a sim card tray. What can I do?

Not sure

Unlocked or not, a sprint iphone 4 will only work on sprint.

The Sprint iPhone 4 is a CDMA only device so it does not use a SIM card.

Unless you can find someone to flash it to Metro or Boost, you have a paperweight.

  • What carriers can the iphone 3gs be flashed to? I have recently purchased an iphone 3gs and i would love to be able to unlock it and somehow use it on a pay as you go plan? my first thought was to unlock the iphone and use it for virgin moble because there plans are the cheapest, but then i figured out that virgin mobile phones don't have sim cards… If i got a at&t pay as you go phone, and stick that sim card into the iphone would it work? are there any other carries that would work?

  • What carriers can I use a unlocked sprint iPhone 4S? I wanted to use it for Net10 but I don't think it's possible. Can someone tell me the US carriers I can use besides sprint?
  • What carriers can a sprint iPhone 4S be used on? I have an iPhone 4S on sprint, an my contract is now over. I would like to give the phone to my cousin, but she can't afford sprint. Can it be unlocked and put on any other carrier?
