Our phones really use uhf/vhf? Dang. I'm a ham nerd but my radio knowledge doesn't really extend beyond those bands.

    Mobile phones use UHF and SHF, where GSM is on the lower end of the spectrum (900/1800MHz) and 5G on the higher end. The newest WiFi standard is at 6GHz.

    5G can go as high as 71GHz, just not in mobile phones yet
