Some additional advantages SIM Locking (Subscriber Identity Module Locking) SIM Locking feature is provided for security purposes. The SIM once locked with a GSM/CDMA module can only work in that and all other SIM s will not be detected by that Module. Network Locking Network locking feature is again important for security purposes. The GSM/CDMA Module can be locked with a specific service provider (IDEA, Airtel, Reliance, and BSNL). Once locked Module will not detect SIM of any other service provider. This is different from the SIM Locking in the way that in this case, different SIMs of one service provider will be detected whereas in SIM Locking, single SIM will work in that GSM/CDMA Module. BTS (Base Transceiver System) Locking BTS Locking is a feature through which the GSM/CDMA Module can be locked with a particular BTS (Base Transceiver Station). Once locked, that GSM/CDMA Module will not be able to receive signals from any other cell site. This is also provided for security purposes and to avoid its misuse and in this case, the GSM/CDMA Module will be fixed to operate only in the vicinity of that BTS and nowhere else.
