Controlling router via SMS by EHWIC-3G-HSPA

I need to make some perfomances (like up/down GRE tunnels) on Cisco ISR 2921 by sending SMS. It could be doing by using 3G modem like a Huawei and a server with some expect/SSH-scripts.

But ISR gen.2 has EHWIC-3G modules, which working with GSM networks and they can send/recieve SMS. I think, that it should be an EEM event or some another way to track comming SMS and process it by TCL-script — get a sender number, SMS body and make usefull perfomances on my router (up/down GRE tunnels in my case).

If I done this trick only by using an ISR router and EHWIC-3G module, it will be much more stable scheme in that we dont have extra components (server, modem) potentially may falls.

Unfortunately, there are too low information about configuring this modules (especially, SMS-part) and I dont find usefull for me.

Any usefull tips or ready solutions on subject? Thanx

Rather you have HWIC-3G module, not EHWIC. HWIC is EoL and doesn't support SMS
