Why can't you just turn off mobile internet?

Many users mistakenly believe that it is enough to disable mobile data transfer in the settings—and the problem is solved. In fact, this only works partially. Here's why:

Firstly, the smartphone continues scan networks operators, even if the internet is disconnected. This drains battery life and can lead to accidental connections (for example, during a firmware update or an OS crash). Secondly, some apps (especially system apps) ignore the settings and try to connect to the network through GPRS/EDGE, if Wi-Fi is not available.

Thirdly, even without active internet, the operator can charge money for registration on the network (For example, when turning on the phone or rebooting it). This is especially true in countries with high rates for incoming calls or SMS. Therefore, simply disabling data is a half-measure.

⚠️ Attention: In some countries (for example, Turkey or the UAE), local operators automatically connect tourists to paid services the first time they connect to the network. This can happen even if you haven't activated roaming with your provider!
