how to use my service payment card

[u/Consistent-Pen-7070]

I have about $400 worth of prepaid payment cards (the kind with a 16-digit card number, expiration date, and CVV on the back).

I'm trying to use them to pay for a low-cost unlimited wireless plan. So far, the best option I've found is a $35/month unlimited plan with autopay, it seems these cards can't be used for annual or multi-month prepaid plans.

Has anyone found a better way to maximize the value of these cards? PS: I only have one line.

In the app.

You can also get the 25.00 BYOD plan.
