SMS is permanently blocked. What should I do?

The SMS function of mobile phone number is blocked for the second time, and can be unlocked by calling the customer service hotline for the first time. Being blocked for the second time, you need to go to the mobile business hall to go through the formalities and sign the guarantee. The third time will take half a year to unlock.

1, SMS is automatically blocked. Generally, short messages sent to others contain sensitive words. Or sending text messages to others in groups, including sensitive words or selling something, are regarded as spam messages.

2. If you want to reopen the SMS function, you usually dial 10086 for the first time. If you are blocked again, you can only go to the local business hall with your ID card and mobile phone card. If you want to write a letter of guarantee, you can't send similar messages in the future.

Extended data

The main reasons why SMS is blocked:

1. Content that contains illegal or illegal words, such as words that undermine social harmony, will be blocked.

2. SMS contains special symbols. The so-called special symbols refer to special symbols, such as @, # ￥% and so on.

3. Different regions have different shielding words and degrees.

4. Unknown channel exception

Avoid sending blocked messages:

1. Replace some marginal words or taboos. Here can be divided into several short messages to be sent separately, and which content has not been received and contains the word, and so on, until the blocked word is found and modified.

2. When testing SMS with mobile phone, you should use the same mobile phone number as the sender. For example, people who send short messages to Shanghai Mobile will use Shanghai's mobile phone number for testing, because short message shielding is mainly aimed at mobile phone numbers, and the shielding methods, shielding words and shielding degree are different in each region.

Now more and more areas are blocked, especially fixed telephone numbers. Therefore, if the input method is changed to the full-angle input state, the risk of text information being blocked by numbers can be avoided.
