Hi Rod and Ray,
BaoFeng and RadioOddity do not seem to be concerned about what is legal or illegal.? Thus, if they could make a radio that would receive in the cellular band, and if they thought people would be interested in buying such a radio, they would likely offer it for sale on Amazon, ebay, and other outlets that facilitate such illegal imports.? I think the radio doesn't have the circuitry to receive those 800+ MHz signals.
Cheers,
