How to completely or selectively disable mobile data on Android: all methods

mobile data on an Android smartphone can become a source of unexpected expenses - especially if you forgot to turn off roaming abroad or a tariff with limited traffic is suddenly exhausted. According to J’son & Partners Consulting, up to 15% of Android users have at least once encountered a situation where background applications “ate” gigabytes of traffic without their knowledge. Even more often, the Internet is turned off by parents to limit children’s access to the network, or by owners of two SIM cards who want to use only Wi-Fi on one of them.

In this article you will find 5 proven methods disable mobile data on Android - from basic settings to hidden functions of the engineering menu. We will look at how to block traffic (for all applications), (only for messengers or social networks) and even (for example, at night). The instructions are relevant for all modern versions of Android - from full (for all applications), selectively (only for instant messengers or social networks) and even scheduled (for example, at night). The instructions are relevant for all modern versions of Android - from Android 10 to Android 15, including shells One UI (Samsung), MIUI (Xiaomi), Magic UI (Honor) and “pure” Android on Pixel or Motorola.

1. Quickly disable mobile data through the notification panel

The easiest way is to use quick settings panel. It works on 99% of smartphones, regardless of brand and Android version. The main advantage: you don’t need to delve into the menu - everything is done in 2 touches.
