I play Minecraft P.E. on my iPad Air, and I have a friend who does as well. My other friends say if you are near each other while playing, it will work. For me it clearly doesn't. I was wondering if you could help with this problem. So, is multiplayer possible on the iPad Minecraft P.E.
Local Area Network
When on the same network, you and your friend can easily join each other's worlds. First, the host must load up a world. Then your friend taps on Play, and there should be an extra world with your username, highlighted in purple.
Multiplayer for Minecraft PE
You may buy an app for $2.99 that allows you to host and join servers with only your device. With the app, you can join PocketMine servers and servers created by other users. Voice chat is one of the features in this app that makes it great. However, there is a player limit of 4 on regular servers. Using this app to join PocketMine servers is better because it lists some great servers available to you.
You can also host a server on a computer and then join on your device. Tap edit and then external. Enter your public IP and keep the port default if you do not know what to do. Make sure you know how to port forward, or this will not work. Remember that you have to manually add servers. You can find great servers on the Minecraft Forums.
Hope these solutions helped!
