Messaging app fragmentation is a real issue, and I currently have to use ~4 different apps, because different people have different subset of these apps installed.

Situation gets even more complicated when you need to message a group of people, because you have to find an app that everyone in the group has it installed (usually, FB Messenger is the best candidate here).

RCS could finally (mostly) solve this in the near future, because practically everyone will have a phone with first-class support for it.
