Bought this app to try it but it’s not free as it claims. You can’t make a call without buying credits and when I bought credits I found out it doesn’t work at all. Simply disconnects right away. SCAM!!!

My grandparents don't use smart phones, but I can still call them often with this app. I think this is the most outstanding feature compared to other international call apps.

This OTO app is wonderful for people like us staying overseas to help call their loved ones for such low rates. Call quality is very good,transactions are fair and quick. Tech support is also very nice.
