Why can I send China mobile SMS commercial advertisements instead of chatting?

Because the media constantly exposed spam messages, the government put pressure on operators, and operators strictly controlled advertising information. In fact, it's all because a few people complain when they receive the information. It is not convenient to do many things now, which is not convenient for yourself. It is suggested to find a professional platform to send advertising information, such as Haoyu Information and 238, which are good, and it will be very depressing to send it by mobile phone.
