Why can't Meizu mobile phone receive information?

There are three possibilities for this situation.

There is a problem with the first operator's network.

Second, the number of the SMS center was deleted by mistake.

Third, some interception software intercepts your messages. First, you call your operator and say that you can't receive short messages. They will refresh your network and give you a short message center number. Please check the advanced settings of SMS ~ settings. Is it the same as your SMS center number? If not, back up the data and restore the factory settings!
