Okay, the wiki cites Striker, so I'll check that first.
Striker just has TL15 ones. 100km range is 500kg (MCr1), 1000km is 2,000kg, 10,000km one is 30,000kg.
MegaTraveller has TL16 stats for those, and increases the ranges but reduces prices: TL16 regional (500km) communicator is 300kg, Cr250,000.
TNE has a base range of 300km, otherwise the same mass and price. And a miniumm antenna area of 1m2.
Other communicators listed in MegaT and TNE go down to shorter ranged handheld sizes, so I'd say that the intention is that Meson comms don't go down to handheld sizes except possibly at TL20 where the regional ones are of negligible mass - but even then there's the antenna area (radio antennas have no minimum, laser and maser ones have a fixed 1m2 area).
My interpretation is that at TL16 what you basically have are vehicle and hub meson communicators, but regular radio comms between person and hub. Colloquially, that set up might be referred to as "personal meson communicators" just as we might refer to our internet as "fibre optic" regardless of using wifi to link a phone to it.
Or "personal" in the sense of "personal dwelling" or "personal transport". You can definitely have every TL16 home and grav-SUV equipped with one.
