Can Verizon wireless sim cards be interchanged with other Verizon phones that use sim cards without having to activate a new phone?
No. The only Verizon Wireless phones that use SIM cards are
Global Phones. SIM cards are only used for the GSM technology.
Verizon Wireless runs off of the CDMA technology. So... if you
switch the SIM card, the phone still won't work because it has
nothing to do with the CDMA and that's what Verizon Wireless works
off of. HOWEVER, you can activate a Verizon Wireless phone on an
existing account by dialing *228 pressing SEND then choosing option
3.
