What should I do if I don't get the news of Xi 'an epidemic prevention?

The failure to receive Xi 'an epidemic prevention message may be due to system congestion. Just get through to customer service and ask them to remove the blacklist. Note that in the later period, the communication company only sent emergency messages to users with normal 4G cards. For users of 2G cards, there are also users who have hosted sim cards in Worry-Free Bank and no longer send emergency messages. During peak hours, because the server is too congested, you may not receive SMS. It is suggested to check again another time to receive it. Accepting SMS is also a condition to ensure that you have a good network status, a smooth operator service location, and ensure that your signal is sufficient and your mobile phone balance is sufficient.
