Waste of Time

This is a dire application. Looks like something from the 90’s and as slow as something from the 80’s. I also can not enter my account to sign in any more. Terrible. I don’t know how much time I have wasted trying to get this thing to work.

Mr Savjani

Dowloaded on 3 different IPhone’s, does not seem to work. Please help

Can’t log in

Won’t recognize my OneSim card number - either number. Can’t log in. Account active through OneSimCard online.

App has worked great until iOS 10

This app has worked perfectly up until iOS released now when using the app on Bluetooth there is a continuous drop in and out creating a clicking chop to the call. Please address this issue...
