Abstract
Systems and methods validate that a subscriber identity module (SIM) number of an end device connected to a network is the same number that was activated for that device. A network device obtains a SIM number and a device universal identifier (UID) during an activation procedure. The network device generates a unique SIM authentication code based on the SIM number, the UID, and a master key. The network device sends the SIM authentication code to the end device during activation. After activation, the network device receives, from the end device, an authentication message that includes a first one-time password (OTP), the UID, a time value, the SIM number, and the SIM authentication code. The network device generates a second OTP based on the UID, the time value, the SIM number, and the master key and validates pairing of the end device and the SIM number when the two OTPs match.
