I send text messages spontaneously with my telecom mobile phone. How many mobile phones have you changed? First, the main version, new mobile phone or spontaneous. What if the problem can't be solved?

Call the manual station 10086 to see if they have blacklisted your number.

Change the card to another mobile phone and see if you can receive the message of 10086. If you can't receive it, it will be on the mobile side, and it may be blacked out by the mobile phone. It can be solved by reflecting it on the mobile phone. Have you touched the center number in the SMS settings? If yes, please call 10086 to ask. I have touched it before, but the message can't be sent out and can't be received. I'll call 1086 to ask.

According to your question, I think it is very likely that your mobile phone number has been blocked.
