Telegram. Been using it for years. I regret that they try to implement features that are not core to the IM world, like their support for voice or video calls that are really junky and buggy --- but overall it’s a great tool, accessible on all platforms without being tied to your phone (like the web version of Whatsapp). As long as I can be far away from the Facebook world, I’m happy.
