This refill card is an easy way to add minutes to a prepaid AT&T GO phone. Scratch the silver coating off the back to reveal the PIN. Then using the phone, enter *888* followed by the PIN and then #. Hit “SEND” and the minutes are added immediately. One can also add the minutes online or by calling. The instructions say that for data devices, it has to be done online. This refill keeps your account active for 90 days.

Good for what it is. Most inexpensive way to have a cell phone. Like how unused amounts roll over. Works for phone calls and texts only. Downside is you can't use it for data on a smart phone.

I have always purchased a $25 At&T GoPhone refill. It has enough value to last me a few months since I do not really make calls, but text more. I add the refill card on the AT&T website and it is easy to add the cards value to my account and to buy feature packages for texting or data easily there as well.

Great value for Prepaid. Only 10 cents per minute. Or unlimited talk and text for only $2 per day when used.

It is convenient to use these cards for refilling a phone when you don't want to keep a credit card on file. The new 911 add on fee (tax) surprised me but the Best Buy representative explained it.
