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.
