What should I do if I receive a mobile harassing call after the port number is transferred to the network?

I'm sorry to hear that you have been harassed by your mobile phone. Here are some suggestions to help you deal with this situation:

1. Serious warning: For any harassing call, you can directly tell the other party that you don't want to answer this call, and you will take action to stop it. This can be done orally or by sending short messages.

2. Reporting: You can report such calls to the local consumer hotline or the Ministry of Industry and Information Technology. They may take action to stop this behavior.

3. Blacklist: If you use a smart phone, you can blacklist this number, so that you won't receive their calls again.

4. Don't reply: If you are not sure about the authenticity of the calling number, please don't reply to phone calls and text messages. This may complicate the problem.

5. Change your phone number: If harassing calls is too frequent or makes you feel uneasy, consider changing your phone number.

I hope these suggestions can help you deal with this problem.
