Now I changed the opinion and an assessment of the program! – Callbacker: Calling App & SMS Review

The program became absolutely useless! Doesn't work even with LTE connection! Only with WiFi! Behind what horse-radish, you will pay for conversation if in the presence of WIFI there is a set of free programs??? And SKYPE perfectly works at LTE!!! Categorically I don't recommend the program for installation!!!
