By default international calling is blocked on each Synfone account. If you need international calling service enabled, please submit a ticket to Synfone Support detailing the countries you'll need access to call, approximately how often you'll be making international calls, and approximately how many minutes you'll use on those calls. Synfone Support will respond with a quote for adding the international service capability to your account. In most cases, international service can be added quickly if warranted.
