GBBest combination of price and experience 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.
