Keepcalling is very good app ,make a call better than any app Very very good keepcalling app...... Very excellent service at vision express ! Astonishingly brilliant team of professionals...”

I have tried numerous virtual calling cards, and Keep Calling is definitely the best by a wide margin. Their billing is spot on, and the features they offer (speed dialing, auto recharging, etc.) are very useful. I just wish they would lower the rate for Peru.

Yes I recommend keep calling to my friends because rate is good and quality of voice is good to and I'm satisfied with this company
