I want to switch my old smartphone that was on an old Verizon smartphone plan into a prepaid plan?
I would suggest calling the prepaid customer service number at 1-888-294-6804 for the steps on how to transfer the phone from a postpaid account to a prepaid account.
You can, but if you are on prepaid, you'll want to activate the old phone at the end of the month to avoid having to pay for another month of service. Each device change requires a new payment...even if you are already paid ahead.
