Summary

Beginning in firmware version 5.x.x, select Cradlepoint routers offer SMS capabilities for limited remote management features. This article is intended to provide steps to configure and use the SMS feature. Please verify with your mobile data carrier that SMS functionality is enabled on your mobile data plan. Please contact your mobile data carrier for information on text messaging rates and options so that you are fully aware of any potential expenses that may occur.

Cellular Modems communicate with the network across two channels, which is what allows the use of SMS communication even when the modem does not have an active data connection. However, there are some caveats to the use of SMS for management purposes that must be considered by an administrator.

  • SMS messages are limited to 160 characters which is useful to be aware of depending on what information you are requesting from the router. Pulling logging info from the router via SMS is possible, but will entail multiple messages, as each line of a log entry has the potential to be longer than 160 characters.
  • SMS is not a guaranteed delivery protocol. Carriers are unable to guarantee that the message will be delivered to the modem or that the response from the modem will be delivered to the sender.
  • SMS messages are slow and can take anywhere from seconds to minutes to be delivered.
  • SMS is not an encrypted protocol and all information is sent in clear text across the network. This includes passwords which are sent with every command string.

To utilize the SMS feature, you will need to know the Mobile Device Number (MDN) of the modem. This can be obtained under Status > Internet > Connections in the Cradlepoint’s Administration Page. Select the Internal Modem and the MDN will be located in the Summary section of the modem Device Information.

Note: SMS is only supported on LTE-capable modems.

SMS Syntax Overview

The basic command syntax for SMS is: ,,[arg1,][arg2,]

All SMS commands are preceded by the SMS Password. Additionally, the trailing comma is mandatory as it tells the Router that this is the end of the command string.
