Minecraft pe play with a friend from home?

Me and a friend both have the minecraft pe version and would like to play in a survival map together. And now my question is whether this is possible if we're both in different places, so not in the same Wi-Fi.

wemn yes what options are there.

You both have to be logged in with xbox and be friends there, then you can invite yourself into a world

So even if we're in different places?

Yes

Thanks. Do you know that because you have rarely already done it?

Yep
