The mobile phone sent a short message to the telecom mobile phone across provinces, and the sending failed.

There is something wrong with the mobile system. Sometimes I send text messages across provinces. You deliver it in the morning. Others will receive it in the afternoon or evening. Even people in the same city have had such problems. My classmate's mobile phone is rather strange. Somehow, a third party can access other people's calls. Are you listening or not? There are many problems in moving.
