How do I insert an ATT SIM Card in a Verizon phone?????

I bought the Palm Treo 650 from eBay. This phone is a Verizon phone but the SIM Card that I have belongs to ATT. How can I change the phone so it can work with my ATT contract????

1. Not possible. Here's the specifics: The Verizon network uses CDMA technology. That stands for Code Division Multiple Access. Verizon phones do not use SIM cards period. AT&T uses the GSM network. THis stands for GLobal System for Mobile. Only AT&T and T-Mobile use it. Only phones can be swapped between AT&T and T-mobile as of right now. In the future, Verizon will develop technology that will allow the same usage as the AT&T network, but as of right now, that's not possible. It is not possible to unlock a Verizon phone for AT&T use either, since Verizon phones do not use SIM Cards. Hope this helped.
2. I don't know where you could go to do t his, but you need to get the phone unlocked so that you can insert SIM cards from any network. Hope this helps
3. You won't be able to. Verizon Wireless phones only work on CDMA networks. AT&T uses GSM. As a result, all CDMA carriers such as Verizon Wireless, Sprint, Alltel, do not use SIM Cards. There is no possible way for you to "unlock" that phone to work on a GSM network.
4. Options are: A) Paperweight B) Switch to Verizon C) resell on eBay
