and reinstall the SIM card, then try again.

How can I connect to the LinkZone

network?

Select the Wi-Fi name (or the SSID) of the LinkZone

on your wireless devices, and enter the Wi-Fi

password.

NOTE Find the default Wi-Fi name and password on

the label inside your LinkZone.

"PIN lock" or "PUK lock" is

displayed on the screen of the

device connected to the LinkZone

network.

This indicates that the SIM card is locked.

To unlock the SIM card, log in to the web UI and enter

the PIN code or PUK code. To obtain the PUK code,

contact your internet service provider.

NOTE If the PIN code is entered incorrectly 3 times,

you will be required to enter the PUK code. If the PUK
