Packet data network (PDN) connection requests from a mobile device may be limited by the mobile device. In one implementation, the mobile device may track an amount of successful PDN connection requests issued by the mobile device over a cellular network and maintain a timer value relating to an amount of time over which the successful PDN connection requests have been tracked. The mobile device may determine an allowable number of PDN connection requests and compare the amount of successful PDN connection requests to the allowable number of PDN connection requests. The mobile device may determine, based on the comparison, whether to block a PDN connection request from being issued to the cellular network.
