Why Is The Roaming Free?

We don't know that the Greek network is allowing free incoming calls. They probably still receive the revenue, but you haven't been charged it by your network, who are balancing it against the fees they receive from people that call you, and they hope to earn from your 'outgoing' calls too.

It may be that some of these mvno global SIMs have done their own direct roaming deals, but I don't necessarily believe that despite what Travis says about his influence on CallKey's arrangements for two years. If they'd promised in return a share of outgoing call revenues that turned out not to exist, ie because callback is an incoming call, then they'd have been rumbled by now
