I need to find a company that can send advertising messages at a fixed point! Wait online!

The key is how far you want to locate. If you want to be accurate to the urban county level, you should be able to find a platform like Haoyu Information Dissemination. But if you want to be accurate to a community or a street, it is estimated that you can only use pseudo base stations. However, the risk is great, and you will be sentenced. Of course, there is another way, that is, if you have the number of this area, just send it directly to the platform. If you ask, it is estimated that there is no.
