So what you're asking, is if there will be a SIM card in other phones, just for the purpose of making it easy to switch contacts, and messages, correct? If so, the answer is no, the purpose of a SIM card is so that the phone can work on GSM networks as well as CDMA networks, making it a world phone. The SIM card is meant for that, it has the extra feature of holding contacts and messages, but that is not what it was made for, and Sprint, being a CDMA carrier does not use SIM cards for their phones, unless they want them to be world phones.

If you want an easier way to back up contacts and Text messages, you should look up either, PIM backup, or, Microsoft my phone. Both these options work very well for Windows mobile smart phones.
