If the SIM card is locked you will need to unlock it with the appropriate
PIN code. You can find out if the SIM is locked by viewing the SIM
Status on the Status page:
If the SIM Status is “ SIM PIN Required ”, then follow the steps below to
unlock the SIM card:
From the menu, select Internet Settings -> Mobile Broadband
-> SIM Security . This will open up the page displaying SIM
Security Settings as shown below:
Enter the PIN code in the “ PIN ” field and then enter it again in the

You may select “ Remember PIN ” so that you will not have to enter
the PIN code each time the SIM is inserted. Alternatively you can also
disable SIM PIN protection by selecting “
Disable PIN ” from the “ PIN
Protection ” drop down menu.
Click Save .
Wait few seconds and verify that the SIM Status reads “ SIM OK ”.
