Calyx Institute is offering Unlimited 4G Internet using a special arrangement with T Mobile. One needs to join Calyx Institute at a Contributor level and pay $500 for the first year and after that $400 per year to get the Unlimited 4G Internet.
I spent the $500 and joined to test their service. On 2/16/2021, I got my Alcatel Linkzone 2 and started using it full time for my Internet connection.
I found the service to be superior to CenturyLink, with significant improvement in the Upload speed. I am getting better than 10 Mbps download and better than 3 Mbps upload. The Alcatel Linkzone 2 via Calyx Institute only operates on the 2.4GHZ and provides a real Unlimited Internet without throttling down the speed.
I presume the speed may depend on the lot location; I use it on Lot 246 and get the maximum three dots signal strength. I placed the Alcatel Linkzone 2 in my living room and have no problem getting good coverage all over my home.
One can connect up to 16 users simultaneously to the Alcatel Linkzone 2.
All and all, I wish I knew earlier that such a service exists; for me, it is an excellent improvement, and I intend to use it until Starlink becomes available, hopefully in a year or two.
Thank you Tom Steinruck for pointing me in the right direction.
