The new iPhones come with a SIM lock which means it is not possible to change the service provider of the phones. There are grey markets vendors who might help you break the SIM lock and use the iPhone for other service providers. But remember, your iPhone warranty will become invalid if you do that. With the mobile phone portability service available you can change your cell phone service providers and still retain your old phone number.
Switching phone providers can have advantages if you are unhappy with your current provider. Most companies will charge a fee if your contract is not up for renewal, which can turn out to be expensive. Speaking with your current provider may help with a phone upgrade if you are experiencing problems with the current one.
