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 on 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 8 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.
NOTE: You cannot add email addresses to the White list. When a phone number is added to the White List, email SMS messages will be rejected.
How to Send an SMS Message You can send SMS messages to the router via phone or email. The key elements are:
1. the modem's MDN
2. the SMS password (defined above)
3. the command
You must know the MDN (Mobile Directory Number) of the modem to send SMS messages to the router. This is a phone number that can be found
under Status > Internet Connections in the router administration pages or under Devices > Network Interfaces in Enterprise Cloud Manager.
