3.4.2 SIM Card Control
(Note: This Section is also Suitable for the USB1 /USB2/USB3 SIM Functions.)
On this SIM Card Control settings page, you can set up the password for SIM card’s authentication.
G2wifi III_USB x 4 will detect automatically the current limit times of PIN code and PUK input for your
SIM card. If the remaining times of PIN code input are less than 3 times, the system will stop all
related functions. You should configure the PIN code of the SIM card on this web setting page, and
enter the correct PIN code again before the reboot of the device.
Note 1: The wrong input of PIN code and PUK in the following setup will decrease the allowable input times of
PIN code and PUK.
Note 2: Any changes on this webpage, the user needs to reset to power to have all related functions work
normally.
