How do mobile phones filter spam?

1. mobile phone is set to intercept

when we often receive all kinds of harassing calls, we can use the interception function that comes with our mobile phone to help us block these calls.

2. Carrier Interception

When we want to intercept harassing calls in mobile phones, we can also help us intercept them directly through telecom operators.

if you are a user of China mobile, you can send a short message KTFSR to 186 to start the anti-harassment service.

if you are a user of China Unicom, send a short message KT to 1655587, and reply Y after receiving the inquiry message.

If you are a user of China Telecom, you don't need to do anything, because the operator has enabled this service for us by default.

3. Third-party software interception

Of course, in addition to the above methods, we can also help us by using third-party software. For example, Tencent Mobile Manager, 36 Mobile Guardian and other software have very useful harassment interception functions, and we just need to turn them on.

2. Harassment SMS

1. Keyword addition and interception

In mobile phones, we always receive a lot of harassing spam messages. If we want to block these messages, we can add keywords to the mobile phone to intercept them. In this case, the mobile phone will help us intercept the messages with keywords.

2. Information filtering

If you are a small partner of the iPhone, there is no interception function in the phone, but we can also help us filter out some harassing short messages by opening the phone settings-Filter unknown senders in information.

3. Ignore

When receiving harassing messages like "reply to TD to unsubscribe", some friends will choose to try to reply to the message to unsubscribe, but in this case, they will be recognized as active users and will continue to receive such messages. In fact, we can choose to ignore the short message and delete it directly, so that our number will be recognized as a diving user, and we will not receive such short messages later.
