The mobile phone housekeeper said that the SMS port was occupied by other programs, and it was too worrying to close the subroutine to restore SMS. What's going on here? Ask for help

First, make sure your mobile phone is off. 2. Check whether the number of the SMS center is correct and the settings are correct. If there are no problems above, please think about whether you have sent spoof messages or messages containing sensitive words in the past two days. If so, your message may not be moved, blacklisted and frozen. Please call 10086 for consultation, or wait for two days! 3. If all the above are correct, it is likely that the landlord installed the software or the memory of the mobile phone is not enough (it is the memory of the mobile phone, not the memory of the memory card), so you need to check your software. This requires a lot of work and may not be found out! The best way is to back up important information, such as information, contacts, etc.
