Not connecting to the internet – KeepCalling International Review

I am a customer of your for over few months now and did not have any major issues till now. But since 2 weeks I am having connection issues. I tried to make an international call and I received the message “It seems your internet connection is not strong enough. Do you want to call offline?”, even after having a very strong internet signals. And when accept the off line call, it says, “ Your authentication failed, Goodbye.” Somebody has to look into this issue.
