Data malfunction

Not sure what you mean by “It went through earlier but then it cut me off”.  ATT does not currently offer a $50 plan unless you already had it. If you are talking about the old 8GB plan, you should switch to the $40 plan, you get more data. Have you tried power cycling the phone? What does your account show, is the plan active? In any event, this forum is not customer support. You must call for prepaid support.

We appreciate you reaching out to us @Tkalka!

Let's check into what's happing with your prepaid service!

• Was the $50 plan successfully applied to your prepaid account? What happened when your prepaid service was "cut off'?
• What was the error message you received along with the code 21? Are you unable to make calls/texts or access your mobile apps?
• What cellphone are you using at this time? Are you currently within the U.S. or overseas? 

Provide us more specific details to continue. 

We look forward to your reply!
