Can you put a sim card from a prepaid minutes phone into an iphone 4?

If you can will it let you put minutes into it please I need to know what about the internet!

No. IPhones don't use sim cards.

Iphones do not run throught sim they run through a system called smp but you can flash it

YES YOU CAN! It has to be a GSM unlocked iPhone. Go to and get the phone unlocked and you can put whatever sim card you want in it.

It is possible, if is from at&t and if its unlocked then you can put any gsm network sim card in it
but it has to be cutted into a micro sim card size
