It is recommended that you have the advanced mobile settings remain at their defaults.

1. Go to Configuration >Interfaces >Mobile >Advanced.
2. Enter the advanced mobile parameters:
SIM PUK
(Optional) If known, the SIM PUK code can be entered in these fields. If the router detects that
a PUK is required due to a locked SIM, this number will be sent to the SIM. A SIM PIN must also
be configured for the PUK parameter to take effect.
Confirm SIM PUK
Enter the PUK code again in this field to confirm it.
Initialisation string <n>
These parameters (Initialisation string 1, Initialisation string 2, Initialisation string 3)
specify a number of command strings that are sent to the wireless module each time a
wireless connection is attempted. You can use these parameters to set non-standard wireless
operating modes.
Before being sent to the wireless module, each string is prefixed with the characters AT, then
sent to the wireless module in the order specified until an empty string is encountered. For
example, Initialisation string 3 is not sent unless Initialisation string 1 and Initialisation string 2
are both specified. Initialisation strings are not normally required for most applications as the
router will normally be preconfigured for correct operation with most networks.
