Telecom users can't receive the intersection of time and space.

The main reason why telecom users can't receive time-space intersection SMS is that their mobile phones are in arrears. No arrears, no signal. You can turn on the flight mode and then turn on the data flow.

Time-space intersection generally refers to time-space companion, which is a new term given birth to the COVID-19 epidemic. It means that my phone number and confirmation number stay in the same space-time grid (the range is 800 m * 800 m) * * for more than 14 minutes, and the cumulative stay time of any number in recent 14 days exceeds 30 hours, and the found number is a space-time companion number.
