SIM Pin Lock
The SIM menu allows you to lock the SIM (Subscriber Identity Module) card in your device.
The SIM card inside your device can be locked with a PIN code for additional security. If
locked, the PIN code must be entered before the mobile hotspot can connect to the Internet
whenever you power on your device. You can also change the SIM PIN.
Enter the SIM PIN and press Save Changes to save your settings. The SIM Status will
be changed to Enabled. Once the SIM PIN Lock is enabled, you need to enter SIM PIN
to connect to the mobile broadband network each time you power on your A50 by
logging in the Web Admin page.
NOTE: Contact your service provider for default SIM PIN code. If you enter the wrong
SIM PIN three times, your SIM will be disabled permanently until you enter the PUK
code from your service provider.
Password Authentication Protocol (PAP) provides a simple method
without encryption for the peer to establish its identity using a 2-way
handshake. Challenge-Handshake Authentication Protocol (CHAP) is
used to periodically verify the identity of the peer using a 3-way
handshake.
