I'm on my tablet playing Minecraft PE. My boyfriend rang me and asked me to join his Minecraft PE world. However, I can't do it because the game doesn't show his world. What's wrong and how can I fix it?
You must be connected to the same network to play together, unless you use a third-party app.
There's a third-party app called Multiplayer for Minecraft PE that allows you to host a server and connect to other networks. It's definitely available for iOS, but I'm not sure about Android or other app stores.
The other option is to connect to the same wi-fi network that the other person is on. This will require you to be at the same physical location as him.
As they said you can play on the same network or same server ,but I play with my friend normally with xbox live accounts we add each other as friends on minecraft and whenever someone plays it's showing which world he's or she's playing but sometimes it doesn't work due to connection and some other unknown problems but if it didn't work we just play on the same server
Hope my answer helped:)
