I've been harassed a lot recently! Ask the method or software of SMS bomb, preferably simple and free, thank you.

You can use the blacklist. Most mobile phones have this function. Simply put his mobile phone number on the blacklist. If you don't have this function, go to the mobile hall and blacklist his phone number so that he can't harass you. If you don't have time to get along with your family and friends, there's no need to bomb his cell phone messages. So as long as he can't bother you, nothing else matters. It's nothing to get in touch with boring people like them. It is not worth wasting your time. Hehe, good luck. Happy years
