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.
