T-Mobile says it blocked 21B scam calls this year

Most of the scam/spam calls originate from overseas, while using American phone numbers:

"Five U.S. states, Costa Rica, Guatemala, India, Mexico and the Philippines are where most robocalls originate."

I imagine it's much more complicated to prosecute robocallers that live overseas, as you're now dealing with having to extradite people.

Around 99% of calls I receive, total, are spoofed to my local area and exchange. The discrimination tech is clearly not being used. Sprint/TMO.

A quick fix could be that you require that the phone number matches the country the call comes from.

Won't solve everything but maybe a little bit.

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.
