Silent Circle offer less countries for more money, in a fair comparison
"Silent Circle claims the number of countries covered is greater than those covered by competitors such as Skype and Viber."
Actually, they're pulling a particularly sleazy and deceptive marketing trick here. They're comparing the list of countries that are included in Skype's unlimited global calling plan with those included in Silent Circle's expensive fixed minutes/month plans, which are also the only countries they let you call. Skype actually lets you call far more countries than they do - almost every country with a phone system, in fact - but they're only counting the countries that Skype lets you call dirt-cheap at prices far lower than theirs.
They pull the same trick with their price comparison, comparing their cheapest $12.95 100 minutes/month plan with the same $13.99/month unlimited global minutes Skype plan. Turns out they're such bad value for money that, for almost all the countries Silent Circle support, the bundled minutes in that plan actually cost more per minute than Skype's pay-as-you-go rate; Skype's monthly plans beat their pricing even more spectacularly.
As far as I can tell they don't even offer any more encryption or security on calls to normal telephones than Skype do. Both encrypt the segment between you and their servers, leaving the subsequent PSTN part of the calls totally unencrypted. Their whole sales pitch appears to be marketing bullshit.
