5.7.8. SMS
Administration
NetModule routers can receive or send short messages (SMS) if enabled by your SIM provider.
Messages are received/sent by the modem which has been assigned to a SIM, so one has to
properly configure a SMS-capable default modem as described in chapter
Please note that the system may switch SIMs in case you are running multiple WWAN inter-
faces sharing the same SIM. Thus, it may happen that a different modem will be used for
communication or, if the SIM is unassigned, any operation will even stop.
Please do not forget that modems might register roaming to foreign networks where other
fees may apply. You can manually assign a fixed network (by LAI) in the Mobile SIMs section
(see
Sending messages heavily depends on the registration state of the modem and whether the
provided SMS Center service works and may fail. You may use the
sms-report-received
event to figure out whether a message has been successfully sent.
Received messages are pulled from the SIMs and temporarily stored on the router but get
cleared after a system reboot. Please consider to consult an SDK script in case you want to
process or copy them.
Figure 5.44.: SMS Configuration
The relevant page can be used to enable the SMS service and specify on which it should
operate. We identify SIMs based on their IMEI number and track their statistics in a non-
volatile manner.
