If you are receiving the message that your account details are invalid or suspended, please consider the following points:
Recent failed payment: Did you recently have a failed transaction? This can happen if the credit card on your account has expired, the card is flagged as lost/stolen or insufficient funds were available. It is possible that a failed payment has put the account in suspended status.
Entering incorrect PIN: Reset your PIN/Password after 3 incorrect attempts, you must wait 15 minutes from the last unsuccessful login attempt.
Entering incorrect account number: Your 10 digit account (phone number) should not contain spaces or hyphens. You may also want to try adding +1 before your number, some users sign up with an 11 digit number instead of 10.
A PayByPhone Support representative can check on this for you if you send your 10 digit mobile number. Submit a request through our website: https://support.paybyphone.com/hc/en-us/requests/new
If you are unable to login to your account, you can also transact in guest mode as a temporary workaround.
