My son loves Minecraft (The mobile app version. Minecraft PE maybe?), and he regularly plays with his friends whenever they are on the same network.

Now I happened to mention that he could play with them on weeknights over the internet, and now he wants me to help him set it up.

I am willing to pay a small fee for a private server for them to use, and I've browsed the Google Play store for some server apps, but I get the feeling that every single one is some kind of scam? Am I being paranoid? And what's up with some servers banning the cool blocks, like TNT?

I don't have a desktop that is always running, so I can't really host my own server.

Any advice would be great! Thank you in advance.

PS. I guess I could be asking in the wrong place, or my question has already been answered, but I'm not into the Minecraft lingo, so I'm having a hard time finding the correct info.
