Can the SMS function of mobile phone number be unlocked after being blocked for the second time? I can't send and receive text messages because I'm bound.

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.

If it still doesn't work, go to the business hall and say that you lost your mobile phone and reissue it, saying that you didn't send the text message yourself.
