Specifications

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.
How to Text from a Phone
1. Open the text messaging tool on your phone and start a new message.
2. In the To field, enter the modem’s MDN.
3. In the Subject field, enter the SMS password and command.
4. Click Send.
