Just in case you want to know the area code to Trinidad and Tobago: +1868. However, please take note that many persons have the magic jack at home with US area codes. Also some people have the Vonage phone service via the computer just like the Magic Jack. However, Vonage charges about US$25.00 per month while Magic Jack is just US $19.00 per year. The Vonage phone service is always on connected to the computer's modem. However, the Magic Jack unit is connected to the computer via the USB bus and is off when the computer is turned off. I do hope that this information was helpful.
