is there an app or any kind of solution to make me out of the network operator? this will make me unavailable while my phone is not turned off.
I work really close to a country border, and I do NOT want my phone to connect to other operators than mine.
Sometimes the operator from my home country will be unavailable for a brief period of time, and the phone will go on roaming. (and it's useless. no phone, no sms, no web.
I have a dualSIM phone with Android 2.3.5. The problem is that it automatically changes the network operator instead of warning me that there is no service.
I was selected the operator with "Search network" option, so it should be manual.
I've searched around, but I didn't find any app for this situation.
Can someone provide a solution?
