Hi, I wanted to ask one thing. Is it possible to restart a modem, sending it an AT command via sms?
There is no such ready feature in any module, I believe, but it is of course possible. Depending on the module that you have you could implement such a behavior. For instance in Java enabled modules you can write a MIDlet that reads incomming SMS messages and takse some actions including module reboot. For the modules with no Java it would need to be implemented in external processor as part of your application. For Java modules it could also be possible to use OTAP feature for this - it is designed for remote updates of user applications but each update cycle includes the rebbot. So it could be possible to configure the service in a way that no app is updated but the rebbot is performed.
There is no functionality in our modules to do that, however on our Java modules, there are two methods you could use:
1. Install your own Java application to Parse AT Commands and react to any SMS in any way you like. See this article: https://developer.gemalto.com/showcase/demo-parsing-commands-over-air
2. Send a dummy OTAP message to the module - this will as a side effect restart the module
