If I have two Blackberrys, if I move the SIM card back and forth between them, will they both work? I am thinking of using an older BB to carry on the boat so I won't mess up my Storm. Is this possible???

I don't believe so. To the best of my knowledge, the phone is tracked by the ESN, not the SIM. Which means that both ESN's would need to be active in the system, which in turn, means there needs to be a separate mobile numbers associated with each ESN. But, I could be wrong...

You would need to swap phones through the internal Verizon system as needed...

I wasn't aware that Verizon used SIM Cards in their phones...curious???

I don't think itis possible either

CDMA does not use SIM cards. It is ESN based & authenticated. SIM cards are for roaming on GSM networks and if you're on VZW, the SIM is just taking up space.

they do only in their world phones. Which the storm is. They use that so you can use the gsm signals over seas
