How to get cheap iphone plan?

Is it cheaper to buy an iPhone from eBay then buy an SIM card?
Don't care too much about a data plan (though that would nice: p after all, it's an iPhone!)
Will the phone company's charge me extra if the card is for a smartphone?

Its better to buy unlocked iphone and use just regular sim cards

Buy the Phone because the SIM card could be corrupted and then it will fry your phone when you try and use it but it's never a good idea to buy a phone off of EBay anyways it's very easy to rip someone off and if the phone is broke or does not work you may not beable to get your money back…

As for Data Plans you have to care about because in order to even use your iPhone you MUST have Unlimited Data because the iPhone uses so much Data if you have a liimited Data Plan you will go though all of your Data in just 5 minutes of using the internet…

There are some smaller services that offer better prices, like Cspire. Cspire.com They have the iphone also.
