Unable to make calls over cellular data – Vonage Mobile – Voice, Text, and Video Review

You will not be able to make international or local calls over cellular data here in the US (T-Mobile, AT&T, etc). Customer service is pretty bad to help troubleshoot the issue. That said, over any Wi-Fi and while traveling (international network data) this product works like a charm.
