With most cases in the world, users need to insert a SIM card (a.k.a. UICC) into end devices to get on cellular
network for voice service or data surfing. The SIM card is usually released by mobile operators or service
providers. Each SIM card has a unique number (so-called ICCID) for network owners or service providers to
identify each subscriber. As SIM card plays an important role between service providers and subscribers, some
security mechanisms are required on SIM card to prevent any unauthorized access.
Enabling a PIN code in SIM card is an easy and effective way of protecting cellular devices from unauthorized
access. This gateway device allows you to activate and manage PIN code on a SIM card through its web GUI.
