Note: With the exception of older Sierra Wireless modules, PRL update on both the Verizon
and Sprint networks is carried out over the air (OTA). Manual PRL update using a PRL file is
not available. To initiate automatic over the air PRL update, click the Start button. Please
note that PRL update is normally carried out as part of automatic provisioning on both
Sprint and Verizon.

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) allow
you to 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 unit 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, e.g. if an incorrect APN has been specified and the
module is unable to attach to the network correctly.
This parameter allows you to specify 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
Post Hang-up string:
This parameter allows you to specify additional “AT” commands that is sent to the wireless
module after it has been disconnected. As with the Initialisation strings, it is not necessary
to include the “AT” as this is inserted automatically by the router.
Wait n seconds between hanging up and allowing another call
This parameter is used to specify the length of time (in n seconds) that the router will wait
after hanging-up the wireless module before initiating another call attempt.
