The 2G network dates back to 1991 and although the world is currently using the fifth generation of mobile phone technologies, the second is still operational. Many countries still have their 2G cells on and this has been a major security issue. For this reason, Google has made a small advance with an update that allows you to disable 2G connection on Android devices .

This has been done with the purpose of preventing the continued exploitation of vulnerabilities in a network whose use is minimal, but puts everyone’s security at risk.

So you can disable the 2G connection on Android

The 2G network currently presents two fundamental problems that put the security of users at risk. The first one is that its encryption is too weak at the moment and it would be very easy for an attacker to intercept calls and messages. The second problem is the lack of authentication between the tower that emits the signal and the mobile device. This is the most dangerous because it gives rise to the so-called “Stingray” attacks.

This type of attack uses a simulator that emulates the signal of a 2G tower, since there is no authentication, all the mobiles that are in its range will connect. This enables the person running the simulator to get mobile data ranging from their calls and messages to web history. For this reason, Google has rolled out an update on its Pixel equipment and the latest Samsung devices to disable the 2G connection.

The steps to follow to disable the 2G connection on these Androids are:

  • Open Android Settings.
  • Go to Network and Internet.
  • Go into SIMs.
  • Disable “Allow 2G”.

If you have recent Pixel or Samsung devices, immediately disable the 2G connection to improve the security of your data.
