Be careful when 5g suddenly becomes 2 g.

If the cell phone signal suddenly turns to 2G in the normal network signal area, please be alert immediately, because you may be attacked by "sniffing" equipment.

The so-called "sniffing" is to steal citizens' personal information by using technical equipment, which is a new telecommunication network crime of stealing citizens' bank cards through the "black ash industry" of telecommunication network.

In this way, criminals obtain the SMS verification code sent by banks and third-party payment platforms and steal the victim's bank card. This modus operandi is concealed and harmful to society.

Precautions:

It is necessary to protect personal mobile phone number, ID number, bank card number, payment platform account number, payment password and other information from being leaked. Turn off your cell phone before going to bed or set it to flight mode to prevent it from being tracked by "sniffer".

If the mobile phone receives a strange SMS verification code, immediately check its bank card and payment application. Once the money is found stolen, freeze the bank card, keep the content of the short message and call the police.
