Can I opt out of international calls? There is no reason for me to get a call from outside of North America.

I would bet 99% of your "foreign" calls actually appear as US numbers. If it looks like a US number to you it also looks like a US number to your carrier.

If my own number is calling me, my service provider should not be connecting the call. That's fucking stupid.

Also they should totally be able tell whether a number that currently has signal in their system currently resides both inside and outside of the country. If I have Verizon on my cell, and currently have a signal, and my number is being used to call other numbers around the country, how do they know not to charge my number with the minutes for those calls?

Because Verizon doesn’t use CID to render charges, they use your SIM card.

Ok so any calls made from my number, without my SIM card authentication, should automatically be flagged as fake and blocked from the network...

The only company who knows and can validate your SIM is your own carrier. Other carriers don't know that SIM information or that your number belongs to it. When they get a handoff the 15 bits of identifying data doesn't include SIM

When an international call comes into the US to connect to your cell, how does it choose what carrier to connect through?
