What is Reddit's opinion of Three inTouch?

From 3.5 billion Reddit comments

They have an app for it in the Play Store. Before the N update it would get stuck on 'Authenticating' or something like that but now it works fine!

I use this app when I have not network coverage but am able to connect to Wifi. I can make calls AND send SMS with this app, and there are other apps for different networks too I believe

Now THIS looks interesting, I wasn't aware of this. It take it this is "always on" in the background, as in you can receive SMS and calls if you're on wifi without explicitly opening the app?

Edit: The reviews for the app don't look too encouraging.

I guess? It's for UK users on the three network

A little google goes a long way. Three texting on the Play Store.
