Otubio Customer Reviews
Call quality on Otubio is great.The calls rates are the cheapest amongst their peers.I am satisfied with using their services for making long distance calls.
Otubio is the best combination of price and experience. Particularly after the last app update the Otubio experience much nicer now. There are cheaper services but experience sucks. And I particularly like the option to choose between data and regylar call. When at home I use data over WiFi and when out and about I use regular phone call
Its good service ,Voice Clear, Connect too fast and also cheaper than other services.
Call quality to Nigeria is loud and clear. Also shows my caller if too. Awesome.
