Operation Manual

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.
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.
