I want to write an app which is able to receive an “emergency call” from another server.
For that reason it should work over the internet and the mobile network.
If, for example no internet connection is available, it should receive the data over the mobile network.
I would get the data from the internet over a push notification, but how can I get data from the mobile network?
I could just send an SMS, but thats just not as nice and clean as if It would be if this works inside the app.
