Suddenly there have been no SMS messages reported in the past two days.

If the poster has been using it normally without any problem, then it is possible that the number of people sending text messages increases during the Spring Festival, causing the SMS channel to be blocked. Because every text message sent requires data conversion, the sending report will be delayed or It is not available for the time being; the SIM card is not very damaged, but the author may also wish to call the local China Mobile customer service 10086 or China Unicom customer service 10010 for detailed consultation!

Please accept my answer! Happy New Year!
