Where I live, messaging using Facebook is the most effective way to communicate with my phone company, my ISP, etcetera. That is the only reason I use Facebook messaging (I communicate with friends using other services) and one of the few reasons I still have a Facebook account. Installing Facebook messenger app is too much just for this.
