No problem! Those are all Northern AZ based Fixed Wireless Internet providers. Searching by the Sedona zip code it looks like only SpeedConnect may service the area with Fixed Wireless, but I would still call around to check.
I do not see a lot of options in the 1 GB range. The only provider in the area I see advertising those speeds is Suddenlink, and it sounds like you already reached out to them.
Wish I could help more. Hopefully another user will provide some feedback for you as well!
