A single 6MHz channel at the top end of UHF band would be enough to implement a universal cellular telephony service - simple calls and texts - at very low cost if phones had modems for it. I think that would be the better use of spectrum.
RF Channels 38-83 have all been taken from (US) TV since the 80s. Mostly used for mobile phones.
rf 70+ is 800 Mhz
rf 52+ is 700 Mhz
rf 38+ is 600 Mhz
Lots of phones support these frequencies.
