For countries that are not included in this list. It's due to one of these reasons: (i) We're unable to ensure the quality of calls in your country (ii) The costs of calls in your country provided by our providers are not sustainable for our business (till we find better rates) iii) There are local country regulations that prohibits us from supporting those countries directly.
For future country addition, it will be evaluated based on the changes in the 3 reasons as outlined above. As they are not within our control, we cannot give a definite timeline. We will be focusing on building other features for the countries supported.
