Ratings and reviews

My first encounter with this app it was quiet smooth. but since all this much of update, the app started to generate network issue, which is; you will be communicating with someone and the person voice will just went mute until you ended the call, and called back. which is very terrible experience. you guys need to work on that if you really needed me to give you guys 5 Star.

Customer care is practically nonexistent for this app. I recharged and never got credited. I called customer care with my SMAT number, it was picked up but I couldn't hear anything from the other end and my airtime ran out. I called from another network but all calls went unanswered. Very terrible EDIT: Finally credited after CS intervention

the app is showing registration fail since 1 week ago have downloaded it . I can't even use it to make call. the app is one of the worst caller app for now. recharge like 3 times before it reflex yet I can't make call. I was referring to call customer service and not available. you people are not but fraud
