Why not completely divorce your phone from your portable computing device?
Before smartphones, they were getting pretty small. You could probably make a phone that was just a voice activated earbud now. Then have a device that was everything but the “phone” bits. You wouldn’t have to accept the locked down aspects that the cell providers demand, you could have all the variety and functionality of your home computer or laptop.
Not enough space for an proper antenna and the battery requirements wouldn’t work plus the thermals the thing would kick off would burn your ear.
The transmission power requirements between Bluetooth and cellular is measured in magnitudes, 3-4 times the power.
The cellular modem and antenna could be fit into the charging case of earbuds but the battery life would still be terrible since most of the case is taken up by the space needed for the ear buds.
That’s not a bad idea.
