Not legally, since all of the frequencies in question require licensing and most are allocated to mobile phone providers.

But yes, this is already possible, in fact, Osmocom has a fully open baseband running on certain phone chipsets.

Note that the Osmocom baseband project isn't aimed at end-user devices, only at researchers. For example it runs part of the stack on the laptop the phone is attached to.

I guess this is GSM, but I heard 5G operates on some license free bands.
