I just did this tonight and it worked without a hitch. If you have an HTC Touch Pro2 from Verizon and want to use your own SIM card while travelling abroad (or even on a domestic GSM provider i.e. AT&T), follow these steps:
1. On TouchFLO 3D, scroll to the ?Settings? tab and click the left soft button for ?All Settings.?
2. Click on the ?Personal? tab at the bottom.
3. Click on the ?Phone? icon.
4. Go to the ?Network? tab and select ?GSM/UMTS only? from the drop down menu.
5. At this point, although your phone won't register a network or get reception to make any calls (other than emergency calls), you can hit the Phone/Send button and dial: *#06#
6. The system will automatically display your IMEI number. Write this number down.
7. Call VZW Global Support (1-800-711-8300) and select the option for technical support.
8. Tell the representative you will be travelling abroad and would like to unlock your SIM. You may or may not be asked for your IMEI number (they should have it on file) after which you will receive the unlock code.
9. On TouchFLO 3D, scroll to the ?Settings? tab and click the left soft button for ?All Settings.?
10. Click on the ?Personal? tab at the bottom.
11. Click on the ?Security? icon.
12. Enter the unlock code you were provided.
13. Click on the ?Phone? icon (next to ?Security? under ?Settings? -> ?Personal? tab)
14. Go to ?Network? tab.
15. Choose ?GSM/UMTS only.?
16. Click on the ?GSM/UMTS? tab, click on ?Band,? and hit ?Get Settings? and you'll find various band options depending on where you will be travelling.
17. To switch back to the Verizon network, select ?Global? from the ?Network? tab.
