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
5.3.3 .
Please note that the system may switch SIMs in case you are running multiple WWAN
interfaces 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 SIMs
section.
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.
We identify SIMs based on their IMEI number and track their statistics in a non-volatile
manner.
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
