Administration
On NetModule routers it is possible to receive or send short messages (SMS) over each
mounted modem (depending on the assembly options). Messages are received by query-
ing the SIM card over a modem, so prior to that, the required assignment of a SIM card
to a modem needs to be specified on the SIMs page.
Please bear in mind, in case you are running multiple WWAN interfaces sharing the
same SIM, that the system may switch SIMs during operation which will also result in
different settings for SMS communication.
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.
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.
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 SIMs
section.
The relevant page can be used to enable the SMS service and specify on which it should
operate.
Routing & Filtering
By using SMS routing you can specify outbound rules which will be applied whenever
message are sent. On the one hand, you can forward them to an enabled modem. For
a particular number, you can for instance enforce messages being sent over a dedicated
SIM. Phone numbers can also be specified by regular expressions, here are some exam-
ples:
Number Result
+12345678 Specifies a fixed number
+1* Specifies any numbers starting with
+1
+1*9 Specifies any numbers starting with
+1
and ending with
9
+[12]* Specifies any numbers starting with either
+1
or
2
