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. These can be used to set non-standard wireless operating
modes.
Each string is prefixed with the characters AT before being sent to the wireless module and
they are sent to the wireless module in the order specified until an empty string is
encountered. For example, Initialisation string 3 will not be 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 pre-configured for correct operation with
most networks.
Hang-up string:
In a typical wireless application, the connection to the network is always on and under normal
circumstances it is not necessary to hang-up the wireless module. Under certain
circumstances however, the router may use the ATH command to try and disconnect the
wireless module from the network, such as if an incorrect APN has been specified and the
module is unable to attach to the network correctly.
This parameter specifies an alternative hang-up string that is sent to the wireless module
when disconnecting a call. As with the Initialisation strings, it is not necessary to include the AT
as this is inserted automatically by the router
