In no version of the MWI that I know of you can communicate with the other worlds.
Why would you need to communicate? You only need to know that the right branch exists.
Also, if “everything happens somewhere” is true, then there must exist branches that look exactly as if communications with other worlds have taken place there, whatever that means.

I’m not keen on discussing the MWI much, but presumably to jump on it you need to find a way to get there somehow.
No, you just need to find a branch in which your exact copy “naturally” spontaneously appeared in the place you need.
I’m not keen on MWI explanations either. As I said, they are unsatisfactory.
