Zusammenfassung:A wireless communication device may include a Subscriber Identity Module (SIM) card configured to store a subscriber profile. The wireless communication device may further include logic configured to detect attachment to a wireless access network; detect a non-activated Subscriber Identity Module (SIM) card; receive a Protocol Configuration Options (PCO) message from the wireless access network; retrieve subscription status information for the SIM card from the received PCO message; determine whether the SIM card has a valid subscription based on the retrieved subscription status information; and instruct the SIM card not to initiate an activation process with a SIM Over-the-air (OTA) system, in response to determining that the SIM card does not have a valid subscription.
