My son Alan showed me he can activate/deactivate caller ID by pressing (pound) 31 (pound) and then the number, from his cell phone (prepaid Orange). However, this didn't work from my postpaid Verizon cell phone. I called 809-220-1111 and asked for an explanation. They said I would have to subscribe to the service (RD1000 +) and then pay a montly fee (RD98). Your best bet would be to buy (or find in a safac?n) a cheap Orange serviced cell phone to be used only for stealth occasions...
