probably not unless you pay a fee to get out of the contract

They are different SIM cards. If you contact Straight Talk they should be able to provide you a SIM card that will work on the frequencies the old iPhone runs on.

Straight Talk does NOT mean unlock! Straight Talk is a pay-as-you go cellular phone service...A company that sells the phones and the service. I highly doubt that the phone would work overseas.

Contact the store where you purchased the iPhone, and pay them to "unlock" your iPhone. Then, any SIM that you insert will be accepted & recognized.

HI if you want to activate your iphone with straight talk sim then you must first check that whether the iphone is locked or unlocked one .If your iphone is unlocked then you can freely use it with any GSM sim .Else if the iphone is locked to some other network provider then until you unlock it you can't use it with any other GSM sim ..You can easily get your iphone unlocked using Mobile-Unlocker.com here they are providing remote unlocking service to unlock all model iphone from network lock .

i dont think so because straight talk has there own company. thats why walmart is the only one who sells their refill cards. that's like since they use verizon towers you can take a straight talk phone and change it to a verizon service but you cant take a verizon phone and change it to straight talk.

It really depends on your ability to be patient with Straight Talk customer service. One night, I was on the phone with Straight Talk from 8:00 until 11:45 working to port a number. ATT had released the number, and for some reason Straight Talk couldn't capture it. It was frustrating. It wasn't the person from Straight Talk being difficult, it was the system. Bottom line, be patient, if this is what you want to do. Good luck!
