假定你Windows 7 Phone與t-mobile相容:
1. 把現用的sim card暫時取下(收好嘍)
2. 買個t-mobile prepaid activation kit (sim card, 有10分鍾), $3, 裝到你Windows 7 Phone,activate prepaid account
3. port the iTalkBB number to prepaid account
4. port the number from prepaid account to Google Voice
5. 把prepaid sim card 取下,把原來的sim card裝回Windows 7 Phone
明白了嗎?
如果Windows 7 Phone與AT&T相容,就用AT&T的prepaid轉。
如果Windows 7 Phone Verizon,那就沒有SIM Card。我不知道怎麽玩。
