80 plan? I'm not sure what you mean by that - an individual plan with minutes and data that totals $80 a month? A prepaid plan? (I don't think you can use the Bold on a prepaid plan-or it has to be on a contract plan for 6 months and then you can use it on a pre-paid...I'm not sure)
Is the phone still active on her account? Is it branded Verizon? As long as the phone is branded Verizon, and the ESN is "clear" (meaning it's not active on another account, and not listed as lost or stolen) then you should be able to dial *228, choose option 1 and activate it to your account.
The Blackberry 9650 can be used with our $80/Smart phone prepaid plan. You can get more plan details on http://bit.ly/U0Zgon and also activate the service with our specialty prepay team at 888-294-6804. I know you'll love the 9650! Let us know if you have further questions or concerns.
