Someone used Zhangzhou Longhai's mobile phone number to send a text message to Sanming, insulting and slandering. How to find this person?

If a dog bites you, you don't have to answer back. If you really want revenge, it is difficult for ordinary people to find it. You must first determine whether he defaulted or canceled the downtime. If he defaults, you can vent in the following two ways: 1. Download a short message bomb and send him a spam message to this number; 2. Leave his number on the gay website, you know. If he has been cancelled, he can only violently crack his account and inquire about his identity information, but the cost may be a bit high, not worth the candle. If you call the police, I don't think it will be checked for you even in your district, because it is difficult to file a case for insulting this by SMS, so I can only help you here.
