I want to join my friend's world but she lives in a different house with different connection. However we do live on the same street.
There is a way, but it is a little hard and costs $2.99. There is an app called Minecraft Pocket Edition Multiplayer or something like that. It is $2.99 and on the App store. With that app, you can click host world and follow the instructions it tells you. It will say open Minecraft, then come back to this app, then host and double click home to go back to Minecraft. Your friend will them click join world and find your world by searching the name, Make sure to put a password on if you do this or other people will join!
