Sometimes mobile network (cellular network) is unavailable for my phone and I won't be informed about call attempts and SMSes. Is there a way or application that notify me (by notification, vibration, sound, etc.) when mobile network is unreachable? I'm using Android 4.1.2

EDIT: By unavailability of mobile network I mean any reason that makes that I cannot call to anyone and others cannot call to me e.g. be in out og scope of cellular network, removing SIM card or anything.

  • Try Macrodroid automation app (free). Trigger > Service unavailable, Action > play (pre configured sound or your own choice) . constraints None

  • Removing SIM card is not a normal action in regular phone usage, so i doubt if you can find an app to that- maybe Tasker can

  • @beeshyams Maybe yes but I have phone that doesn't work as should and inform me that SIM card was removed.

I like OpenSignal, it will notify you when you leave a coverage area and also help you figure out the best service provider in your area.


  • @Greck Did that answer work out for you? Jul 21, 2016 at 0:13
  • It seems that it doesn't notify when mobile network is inaccessible due to removing a SIM card. This happens for me sometimes when my phone falls on the floor.
