GA309 : Oops, we hit a snag. Come back later and try again.

Hi - I received my SIM card in the mail today. I followed the directions and installed into my Moto Power (2022) phone. I have no service and clicked the link to activate. When I input all the information, I receive the GA309 error.

I've tried with Wi-Fi and on 'cell' service. I bought the SIM card on the website.

How can I activate my phone, so I have service?

Thank you!

We are here to help with getting your new Prepaid service activated, @allison1081.


We do understand how important it is to stay connected! There are many ways to activate service. To activate your Prepaid device from your phone, follow these steps:

  1. Before activating your AT&T PREPAID account from your device, make sure it has been charged and that the AT&T PREPAID SIM card has been inserted (some devices may have the SIM card pre-installed). Once charged, turn the phone on.
  2. You will receive a free AT&T text message. Select the unique URL sent in the message.
  3. The SIM/ICCID number and IMEI number will auto-populate. Enter your 5-digit service zip code and the passphrase code, then select Continue.
  4. Select whether you would like to Activate 1 device or more than 1 device.
  5. Select the desired rate plan, then scroll down to select the desired option for AutoPay. Select the check box to accept the Service Agreement, then select Continue.
  6. Enter your email address, then select Continue.
  7. Select the Payment Method from the drop-down list.
  8. Enter the requested payment information, then select Continue.
  9. View your new phone number and restart your device.
  10. A free "Welcome" text message will be sent. Select the link in the text message to set up your account password
  11. Enter and confirm your new password and 4-digit PIN, then select Submit. Select OK.
  12. Update your personal information, then select Submit.
  13. An email with a verification code will be sent to the email address entered previously. Enter the verification code, then select Validate. Select OK.
  14. Your AT&T PREPAID account has been successfully created and you are now logged into your account. Review the Account Summary page for details.

To activate online, enter your SIM number and the IMEI number.


To activate over the phone, call us at 877.426.0525 for automated instructions. You will need to know your SIM card & IMEI number for activation.


We hope this helps! Let us know if you are able to successfully activate your device after following these steps.
