Prepaid phone plan balance transfer to tablet data plan

[saltydogg]

I have a prepaid phone that was Alltel now Verizon.  I have a large balance on the account.  I want to purchase a iPad Air and transfer that balance to either a prepaid or postpaid tablet-only data plan.  Is that possible?  How would I go about doing that (visit a store, call a cust. svc. number, etc...)?
