Has anyone been down to the US lately and tried using a Google pixel phone ? Any luck making phone calls, I've been told it won't work still, just curious if anyone can confirm this?
I have a Google pixel 6 pro. It didn't work. I was able to send texts and use the data still. So you can still use apps like Whatsapp etc.
You need a VoLTE enabled phone to make calls in the US via Lum/AT&T. The Pixel 6 pro and Pixel 7 pro are both capable of using VoLTE, it's just that Lum hasn't bothered to provision any Pixel devices yet for VoLTE. There's a device compatibility list buried in their website that hasn't been updated since March.
At&t is extremely stringent with their requirements. A Canadian purchased Pixel 6 pro will not work in the United States. Even if you buy an AT&T SIM card from there. I ran into that issue personally. They actually won't even allow you to use data or texts.
"Lum hasn't bothered to provision any Pixel devices yet for VoLTE. "
To clarify what I said above, Lum is unable to provision any Pixel device for VoLTE until Google approves their request to do so (which Google has yet to do). Hopefully that happens soon.
VoLTE on the Pixel 7, Pixel 7a, Pixel 7 Pro, Pixel 6, Pixel 6a and Pixel 6 Pro models is now working on Canadian and U.S. networks. Make sure you have the latest OS and VoLTE turned on to avoid issues.
