send short messages

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 happily, you don't have to bomb his cell phone messages. So as long as he can't bother you, nothing else matters. There is nothing to contact with boring people like them. It's not worth wasting your time. Hehe, good luck. Happy years
