What should I do if I receive mobile phone text messages, harassing phone bills and spam messages?

10086 is useless. It is very complicated to submit spam messages.

My method is to leave a contact information of house purchase and education in the spam message, and then download a free internet phone. Generally, free VoIP has a probation period. According to that contact number, you can always dial and hang up when you get through.

Hang up and dial again, if he dares to send it in groups, I will dare to harass it with a free phone, damn it,
