Why doesn't the mobile phone show the wrong number when it hits the seat?

It's no use changing the card. It's not the card. Your mobile phone card should be a new mobile phone. After adding a number segment to your mobile phone, you didn't notify Telecom or China Unicom (fixed-line provider) to maintain your number segment data. So when the landline calls your mobile phone, it prompts that you can't find your number. This problem can be complained in the mobile business hall. You can also call 10086 directly to ask for a reply. It should take several days to deal with this problem.

The number segment is the first 7 digits of the mobile phone.

I hope you will be satisfied with my answer.
