Re: [Instruction]How to Keep Unlimited Data on Verizon
not necessarily. Are you on a family plan? If so, are you using an UDP line's upgrade to upgrade? Do you have any basic phone lines on your family plan? Give us the details.I'm upgrading my 3g UDP phone to a new 4g phone. When it comes time to activate the new 4g phone on my line I'd need to go to a Verizon store and get a new SIM card, correct?
