Awesome application
Please give the caller a heads up that there call is about to end because lack of funds. I’m tired of it hanging up on my father. I would like to end the conversation politely, please.
It was working perfectly for a month then just stopped working.
"sound quality is very good. Almost like you are using your cellphone provider directly"
Call quality to Nigeria is loud and clear. Also shows my caller if too. Awesome.
I have tried Otubio a couple of times and it connected really quick.
I love this App. Very clear international calls at awesome low rates. I love. I love!!
