1. A method comprising:
sending, by a user equipment (UE) device, a plurality of attach requests to a base station using a radio access technology (RAT);
determining, by the UE device, that each of the plurality of attach requests has failed;
overriding, by the UE device, a triggering of a backoff timer, wherein the UE device is barred from attaching using the RAT if the backoff timer is triggered and running, in response to determining that each of the plurality of attach requests has failed;
initiating a retry delay timer, wherein the retry delay timer is of shorter duration than a duration of the backoff timer; and
sending, by the UE device, a first attach request to the base station using the RAT after the retry delay timer runs out.
