How do you manage to keep up with the latest messenger fashion ? I gave up when people changed from MSN to Skype. Then they changed to Facebook and now they are probably using Whatsapp or some other I don't know of. When I want to chat I use IRC. And I've also setup asterisk as a SIP server for voice calls.
i still use Skype, specifically Skype Lite is quite nice, so that's one option for video and chat, other option for video, chat and SMS is Signal and if neither of them works for you, you can always email me or call me
used wechat because lived in China, but uninstalled everything Chinese after leaving that place, tried Facebook messenger (later Lite) for few months until decided i don't really need to have Facebook account and anything to do with Facebook, which means i ain't gonna install WhatsApp either, so there are not many other options left
