I have a prepaid sim card from att, and I'm thinking about buying an IPhone from a friend. I want to know If I can just put my prepaid sim card into the Iphone, and would it work? will the charges stay the same?
Ya sure you can use AT&T prepaid sim in the iphone without any issues only if it is unlocked one else if the iphone is locked to some other network provider then it wont accept AT&T sim until you unlock it ...You can easily unlock the iphone through online providers like Unlocking4U.com here they are rendering remote unlocking service to unlock all model iphone from network provider .You first check that whether the service is available for your country and network provider .If yes then pay for it and unlock the iphone then freely use it with any GSM sim ..There will be no changes in the charges ....
