GSM Mode Not Functioning

A: In standby mode, press the left soft key for MENU, then press 7 for SETTINGS, 1 for PHONE MODE. The following options appear in the display:

Verizon (CDMA) Int'l (GSM)

Use the navigation keys to highlight the desired mode of operation, then press OK on the keypad. A dialogue box appears in the display asking to change modes. Press the left soft key for YES to change modes, or press the right soft key for NO to return to the PHONE MODE options list. If YES is selected, the phone restarts and powers up in the selected mode of operation

Anyway, the tech had me take the SIMM card out and read the number to him. He then input the number into the system and within about 30 minutes it worked fine (and I mean really fine as I've mentioned in an earlier post).

The problem I've found is that Verizon support personnel are a lit...
