There are a couple of reasons your account may be suspended. Usually, your account needs to be renewed or there was a problem with your payment details.
Your renewal failed
If we tried to charge you for your plan renewal, but the charge did not go through, your account will enter an Airtime Expired status. You can put a new method of payment on file by going to unrealmobile.com/my-lines and clicking on the line effected. Then click "UPDATE CARD".
Enter new, valid payment information.
Airtime Expired Status
If your plan has reached the end of it's 3, 6, 12 or 24 month term and it's time to submit another payment, your account will enter Airtime Expired status.
Promptly resolve this by logging into unrealmobile.com/my-lines, clicking on the line effected and then click on "BUY MORE". Select "PAY MY BILL" and submit a payment for your current plan to renew the account.
