SMS
SMS (Short Message Service, or text messaging) requires a cellular modem with an active data plan. SMS is not
designed to be a full remote management feature: SMS allows you to connect to the router for a few simple
queries or commands with a text messaging service (e.g., from your phone). A modem that does not have an
active data connection may still be reachable
by SMS because Internet traffic and SMS
traffic operate on separate channels, so SMS
can be used to bring an offline router back
online.
SMS is enabled on the router by default.
However, it only works if SMS is supported
and enabled on the modem. Most modems
have SMS enabled by default, but the carrier
may charge a fee for each text message sent
or received. Contact your carrier to review
these fees and/or to enable an SMS plan.
Important notes about SMS:
•
Messages are limited to 160 characters.
•
SMS is not a guaranteed delivery protocol. The carriers do not guarantee that the SMS message will be
delivered to the modem or that the modem's response will be delivered to the sender. This means an
administrator might have to send messages multiple times before the desired action is performed.
•
SMS is a slow protocol. It can take seconds or up to a few minutes for messages to be delivered.
SMS messages are not encrypted; they are sent in full readable text over the network.
•
Enable SMS support – SMS support is enabled by default on the router. Deselect this to disable.
Password – By default, the password is the last eight characters of the router's MAC address (i.e., the Default
Password on the product label). You can change this password to anything between 1 and 16 characters. It
should be long enough to be useful for security but short enough to easily type into your phone (or other
texting client).
White List – This list is blank by default, which means that the router will accept SMS messages from any phone
number. Leaving this blank is unsecure, so Cradlepoint recommends that you add phone numbers to this list.
Once any numbers are listed, only those numbers have the ability to connect to the router via SMS.
SYSTEM LOGGING
Logging Level: Setting the log level controls which messages are stored or filtered out. A log level of Debug will
record the most information while a log level of Critical will only record the most urgent messages. Each level
includes all messages from all of the levels below it on the list (e.g. "Warning" includes all "Error" and "Critical"
messages as well).

Enable Logging to a Syslog Server: Enabling this option will send log messages to a specified Syslog server. After
enabling, type the Hostname or IP address of the Syslog server (or select from the dropdown menu).
•
Syslog Server Address: Select the Hostname or IP address from the dropdown menu, or type this in
manually.
