SIM Card Lock – Select an option to manage the SIM card.
PIN Required – When selected, it locks the SIM and requires a PIN to be entered.
No PIN Required – When selected, the SIM is unlocked, and no PIN is required. If the SIM was previously locked with a PIN, enter the valid PIN to unlock the SIM.
No Change – This is the default setting. When selected, the current lock state of the SIM is not changed. If the SIM is locked, the currently configured PIN is required to use the SIM.
SIM PIN – Enter a four to eight-digit number, which is the SIM's password.
Note
A PIN change will occur if the SIM PIN is modified and the old PIN has previously made a successful connection. If the SIM has never been locked a default PIN (carrier specific) may be required. You can later change the PIN after successfully locking with the default.
Show PIN – Display the SIM PIN value in clear text.
Authentication Protocol – Set this only if your service provider requires a specific protocol and the Auto option chooses the wrong one. Choose from Auto, PAP, and CHAP, and then input your username and password.
APN – Some wireless carriers provide multiple access point (AP) configurations to which a modem can connect. Access point name (APN) examples include “isp.cingular” and “vpn.com.”
Default – Let the router choose an APN automatically. This is the recommended setting.
Default Override – Manually enter an APN.
Select – This opens a table with 16 slots for APNs, each of which can be set as IP, IPv4/v6, or IPv6. The default APN is marked with an asterisk (*). You can change the APN or select a different APN. For Verizon modems, only the third slot is editable. Changes made here are written to the modem, and a factory reset of the router does not impact these settings.
