These days, I always receive the so-called arrearage notice from Telecom, but every time I send a text message in the form of a landline, and both times it is a different number.

The contract number is the same. If your ID number is yours, you'd better go to the telecom business hall to find out who made the call with your ID card. If you owe money, make it up quickly, or your personal credit will be affected, and you will be in trouble-you can't even take the high-speed rail in the future, and you can't get a bank loan!
