Assume you have a Tracfone as your "burner" phone. For mulitiple years you have, once-a-year gone to the local Wal-mart and purchased an airtime card that extended the service date by 1 year and added enough minutes to get you through the year.
Now, it's approaching time to add more minutes and extend the end-date. You go to the local Wal-mart and they don't have a 1-year card on the shelf, so you buy a 90-day card with cash. You take it home and after scratching off to reveal the PIN the tracfone system tells you it is invalid.
Next you goto the local Bestbuy, find a card that doesn't have a scratch-off but the instructions say the PIN number will be printed on the receipt. You attempt to pay cash but the cashier requires display of an ID, so you cancel the transaction.
Then you come here and ask for suggestions on acquiring airtime cards without providing ID while using cash.
Try another Wal-mart? other store? Or have things changed such that airtime cards can no longer be purchased without providing ID?
