Thanks for the info!

A 6T just arrived today and I successfully installed Ubuntu Touch. I couldn't get the windows installer to work, but the Linux Mint installer worked perfect.

It's a great looking operating system; it's more polished than I would have thought. The Suru dark mode on Ubuntu Touch is significantly better than the original android 9 high contrast mode. I appreciate the security features. It runs well. I haven't tested the calling/texting yet, but hopefully soon. It runs 3D games with zero lag. This thing is a hot rod. Finding a decent secure phone has been a difficult task, but I think this will be perfect.

Thanks again.

@rondarius Thank you!

I had no idea about UB Touch not yet supporting VoLTE. Every carrier I have found says they require it, yet people are apparently still using Ubuntu Touch with carriers in the US. I don't even want VoLTE. I just thought carriers wouldn't allow me to make calls otherwise. Maybe VoLTE isn't as required as I thought? I was thinking about switching to Mint or Ting or some other pre-paid service anyways.

How is carrier support for devices with Ubuntu Touch? Are there any specific carriers the community has had good luck with?

An update regarding the network functionality: The phone works on the 4G network of my carrier AND I am able to force the phone to run in 3G only mode(what a fantastic feature). My carrier said that they already shut down 3G(the stated reason why my other phone was shut off), but apparently not yet. It's great to be able to use a 3G phone again. I far prefer 3G, so this is an invaluable feature.
