The secure, fixed-rate voice and data calling
plan works on Apple iOS and Android smartphones and, eventually,
on Windows Mobile systems, the Geneva-based firm said. Callers
can reach 79 countries, including China, Russia, most of Europe
and the Americas. Large parts of the Middle East and Africa are
not covered.
The service marks a sophisticated challenge not just to
traditional phone carriers -- who still by and large charge
steep roaming fees to international travelers when calling from
outside their home market -- but also to newer, voice over
Internet services that have sprung up over the past decade.
For while Silent Circle undercuts major competitors' roaming
costs in many countries, the service's basic attraction lies in
its distinctive security features.
While no one is immune to such snooping, Silent Circle offers
customers a secure means of encrypted communications that
disposes of all records of calls, texts or emails.
The new calling plan starts at $12.95 a month for 100 minutes of
outbound calls and runs up to $39.95 for 1,000 minutes of
calling, comparable to premium price plans offered by Internet
communications services such as Microsoft's Skype and Rakuten's
Viber -- but with much higher levels of security.
