Is there a better short message platform where you can receive short messages as long as you pass by a certain area?

This kind of regional short message can only be realized by pseudo base station, which is illegal and not recommended, and it is not worth the loss. Don't think for free. This is not a good thing. It's good to spend money to do things these days. Even if you spend money, you may not find something useful. We have spent a lot of money. The Haoyu information link used now is ok, but they don't know if they can send it to you.
