Abstract:
Techniques and architecture are provided for preventing narrow band (NB) SIMs from being used in a non-NB devices, e.g., high bandwidth devices such as, for example, smartphones, tablets, etc. In configurations, a user device is provisioned based upon a NB international mobile subscriber identity (IMSI), a NB-indicator and a type allocation code (TAC) combination. An IMSI, NB-indicator and TAC mismatch helps prevent NB-SIMs from being used in a non-NB device. In configurations, when a user device attempts to access or register with a wireless communication network via a narrow band network of the wireless communication network, the wireless communication network will verify the IMSI, the NB-indicator and the NB-TAC combination for the user device in order to allow the user device to access the narrow band network of the wireless communication network.
