I’ll message you with my Skype and Messenger profiles… I prefer Messenger, as Skype calls don’t show up on my iPad unless I’m logged in, which makes it kinda useless as an impromptu chatting tool.
Remember Messenger from back in the day? they linked with Facebook a few years back and became Facebook Messenger, but it can work independently of Facebook, and the Internet calling is free
The Apple FaceTime app is decent, but you need a Mac product for that, but there are now similar face-to-face Android apps to it… which I’ve heard are just as decent
There’s always Whatsapp… free messaging and calling.
