App needs some work
The worst app I’ve ever used for international calls. I did put money but I couldn’t call.
Great app, highly recommendable
Awesome application
App need to add credit by AppStore’s
Thanks good app if you add that I can add credit by AppStore’s it will be good
Warning of depletion of funds during call
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.
Response from developer
Hello, we apologize for the inconvenience. The last minute remaining announcement was removed because most users considered it a disturbance. To prevent your call from disconnecting due to no balance, you can set up auto-recharge from your account on the website. This ensures you always have call credit and calls will not end due to no credit on your account. If you have any more issues, please email us at support@otubio.com or open a support ticket directly from the app. Regards.
Doesn’t work anymore
It was working perfectly for a month then just stopped working.
