Can mobile phones block short messages? (Discussion on methods and precautions of blocking short messages by mobile phones)

With the popularity of smart phones, SMS has become one of the indispensable communication methods in people's daily life. However, some short messages may bring us harassment and trouble, such as advertising short messages and fraudulent short messages. So, can mobile phones block text messages? This paper will discuss the methods and precautions of blocking short messages by mobile phones.

First, the mobile phone has its own shielding function.

Many smart phones have their own SMS interception function, which can be realized by setting. Take iPhone as an example, enter Settings-Information-Unknown and Spam-Filter-Add New Filter, and you can add keywords, phone numbers, senders and other information to block. Android phones can find options such as "Settings"-"Spam SMS Filtering"-"Add Number" in the SMS application.

Second, third-party application shielding.

In addition to the shielding function of mobile phones, you can also download third-party applications to realize SMS shielding. For example, 360 mobile guards, SMS harassment interception masters, SMS housekeepers and other applications can all achieve SMS interception. These applications can intercept short messages according to keywords and phone numbers set by users, and can also classify short messages, so that users can manage short messages more conveniently.

Third, matters needing attention

When using mobile phones to block short messages, you should pay attention to the following points:

1. Don't reply easily or click on the link in the text message. Some scammers will send false information through SMS to lure users to click on links or reply to information, thus defrauding personal information or property.

2. Don't block messages at will. Some short messages may be important notices or reminders, such as changes in bank card balance and flight delays. Therefore, when blocking short messages, we need to think carefully to avoid missing important information.

3. Clean up the blacklist regularly. Because the SMS blocking function will block the specified keywords, phone numbers and other information, it is necessary to clean up the blocking list regularly to avoid missing important information.
