Sometimes our operator's promise to have the signal in 99% of our country is not enough. You will find some useful instructions below on how to improve the signal in your device in case you happen to be in need.
The more users a network transmitter has, the worse signal you get. This is called "cell breathing" - it reduces the radio coverage inside the smartphone (which is the capacity to catch the singal from the transmitter) when the intensity of traffic increases. The operators also warn us about the "white spots" (in elevators, underground parking lots, underpasses etc). The problems with signal can also occur in mountains, woods - trees can actually be a very good signal blocker. When you happen to be in a "white spot" it usually helps when you slightly change your position. But what to do when walking around in search for signal doesn't bring any positive results?
