That's a good question. Maybe they are able to make a kind of "shortcut" so that it won't be necessary to transfer each call twice over Atlantic

.
Or they are just going to create "dual number" SIMs. I mean that each SIM will have both a +1 number (maybe it will be technically just a number of a US MVNO) and a +44 Manx number for worldwide use. In this way, it could make it possible to avoid "regular" transatlantic call forwarding (and its costs, of course).
But this is only what I guess/suppose - no real knowledge behind!
