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     Now I changed the opinion and an assessment of the program Idankin

Strange connection fee Have difference between displayed price and real money spent     Not clear writing off money AlexanderR_

It doesn t even work all it does is take your money     Horrible Flower_alfaro
