free calls anywhere without 3G and WiFi
Mobile telephone is convenient, because everybody has one, but it is certainly expensive when you dial internationally. Skype or Viber service simplifies significantly international communication, but it is not reliable or accessible if 3G and WiFi is weak or not available and you have to pay extra if call recipient is not logged-in into the service.
Avox solved those deficiencies of Skype and Viber. It works when 3G and WiFi are not available and it is free to call either landline or mobile phone regardless of its 3G/WiFi access. This is achieved by Avox proprietary solution that lets sharing users mobile minutes to the Avox cloud and reallocate them among others Avox users and regular phone users.
