How else can I save money?
Buy cards for a small amount of money - for example, $2.00 or $5.00. You are buying fewer minutes. But you will not lose much money if the card does not work.
Check the expiration date. Be sure you can use all the minutes by that date.
Make sure you see a customer service number on the card. That means you can get help if you need it.
What if I have problems with a card?
You might have a phone card that does not work. Or a card with fewer minutes than you thought. If you do, report it:
Call the Federal Trade Commission at 1-877-382-4357 (TTY: 1-866-653-4261).
Tell the person on the phone what happened. You can give as much or as little information as you want.
