If they are so rural ISPs won’t take them, why would a cell company deploy 5G in a super sparse area?
For example TMO and VZW will only hand out home cell modem if you live within half mile of a major interstate. If not out of luck aside from Starlink.
Yup or colo is full and won’t accept any more changes. So one has to wait until someone else gives up space and then a fire sale on the newly freed space.
