Got it to work with straight talk at&t! like is already known from the previous posts it works except for call audio.

@rocket2nfinity thanks I'll try a straighttalk sim when I get a chance to in the next few days

I stumbled upon my nexus 6p today and decided to see if there was anything I could do with it and found this forum and have followed the steps abdicate installed Ubuntu touch.
I am wondering those that have installed it as well what carrier did you have success with because I haven't been able to get verizon to work at all.
