Excuse me, can you help us send text messages in designated areas or groups?

It depends on how large an area you want to specify. If the accuracy is relatively high, such as requiring a community or a store, you need to use a pseudo base station, but this is illegal. Now it is estimated that few people dare to do it. If the scope is relatively large, for example, send a short message company such as a city, district or county. For example, Haoyu Information and Chuangchuang can all be realized.
