Then every time I travel overseas I cannot use my phone or a US phone number? What about living close to Canada, Mexico, Caribbean…etc and you pick up international towers?

It’s an easier fix, but not really a solution.

The reality is that everyone wants fairness but no one really wants government regulation (Russia is a great example of this where your phone number is essentially treated like an assault rifle. Registered, monitored, and geo-tracked).

But that would be roaming, not a us number originating from a non us phone line.
