I took a look at mesh core, found out the app was not open source, and immediately ditched it. If it were open source, I would be more interested. I haven't tried other L.O.R.A. protocols such as reticulum though. If you live in a metro area there's a good chance there's going to be other nodes that you will be able to connect with. If you live in a rural area that might be more difficult and you might need to get a solar node and put it up on like a 30-foot flagpole or something just to increase your range a bit. Height is might after all. A 30-foot flagpole is going to get you quite a bit farther than a node in your window and a 250-foot tower is going to get you much farther than a 30-foot node.
