I reckon the 12 (I hope miles not km) on see, aka the sovereign waters around each country would make them heaps more popular indeed. International roaming, I am not sure about. Generally speaking you could already roam with europe for example so it would only add value if you roam outside of europe. Sure, people do but then 2 months is not a lot of time to do so. I guess for people living on the edge of a region, it would be beneficial, for most other purposes it is not.
Funny how in OZ you guys still have shall we say bad luck. Now with starlink the coverage has increased dramatically over the country and STILL it is heaps expensive (from my POV). I don't even get the option for 50GB over here, I just get the "standard" terrabyte since uplink stations and available bandwidth to/from them is a no brainer in this densely population postage stamp. A lot of people over here can get 8gbit internet over fibre at their home for 80 bucks.
Feeding starlink's satelites in OZ is still somewhat of a challenge it seems so prices go up (naturally). Maybe, perhaps, one day... Also makes me wonder how the capacity of the intercontinental uplink into australia and new zealand is doing :)
In any case, back to starlink and especially calling itself. We can conclude that calling works a lot better over starlink, as long as you have a cell phone (and provider) that support wifi calling, compared to cell service or even sat phones. However, would one argue that there is no longer a need for a sat phone in case of emergency? Those things are cumbersome, expensive and generally indeed a bit of a faff to use so if they could be skipped it would be a benefit I reckon.
