The quality of a call depends on two factors - the internet connection you use and the reception of the person you are talking to. With a decent Internet speed, you will not notice any difference between OpenPhone and regular calls.
We support calling using your carrier network if you have slow Internet. Learn more here.
If you have any feedback or comments on the quality of calls, please don't hesitate to reach out. We'd love to be of assistance.
PS - When you create an account you get an option to place an automated test call that lets you experience call quality yourself. You can also call us at 1 855 746 6304 if you'd like a live test.
