Security experts warn that disabling 2G can block one of the easiest phone scams.
A new type of cyber fraud
The Civil Guard has warned of a scam originally started in Spain that uses fake antennas to intercept mobile connections.
The tool behind it
Criminals use portable devices known as “stingrays,” which mimic mobile towers and trick phones into connecting to them.
Why it’s dangerous
When a phone connects to a stingray, it can be forced onto old 2G networks that have almost no encryption or protection.
How they exploit it
Attackers use these fake networks to send fraudulent SMS messages that appear to come from official sources.
Hard to detect
Because the messages pass through what looks like a normal carrier connection, they often bypass spam filters and security tools.
Simple prevention
Experts recommend disabling 2G connectivity on Android phones to stop the device from connecting to these unsafe networks.
How to do it
Go to your phone’s Settings, open Networks and Internet, and select SIM.
The key step
Locate the option “Allow 2G” and switch it off — it won’t affect normal phone service or 4G/5G use.
Why it matters
Turning off 2G eliminates one of the easiest routes cybercriminals use to reach your phone.
Widely available tools
The stingray devices used in these scams are easy to buy online and require almost no technical skill to operate.
Stay protected
Disabling 2G, keeping your phone updated, and avoiding suspicious texts greatly reduce your chances of being targeted.
