Magic Jack Pros & Cons
Pros
You cannot beat the price and associated cost savings. Compare $19.95 a YEAR to the $25.99 per MONTH charged by Vonage or $29.99 or more per MONTH
by your cable or phone company. Save $500 or more per year and get rid of your monthly phone bill.
It's portable. Take it with you when you travel and use it anywhere you have a high speed Internet connection, even when traveling
internationally.
You can even send Magic Jack to family and friends in other countries. Then they will be able to make and receive calls to or from any U.S. or
Canadian phone number for free.
You can make calls directly from your computer using a USB headset instead of using a telephone handset if you prefer.
Ease of installation. We plugged the Magic Jack in and it installed itself flawlessly under Windows Vista, Windows XP Home Edition and Windows XP
Professional.
Unlimited Local & Long Distance Calling (At NO additional cost.)
Cons
When your power or Internet connection are down, you will be without phone service. Of course this is not a shortcoming of Magic Jack alone. This
is true of any digital phone service.
Magic Jack will not work with Satellite based Internet connections.
You will be assigned a new phone number in the area code of your choice when installing your Magic Jack and setting up service. Not all area codes
are available. Check this list to see if your area code is available.
Conclusion
Magic Jack delivers on its promise of crystal clear calls, provided your Internet connection is the right combination of speed and quality. We suggest
at least 500 Kbps upload speed and 60% Quality of Service (QOS) for excellent call quality. (To test your Internet connection speed and quality, visit
the link provided in this review.) Of course, the real test is to try the product. Fortunately Magic Jack has a free 30-day trial offer if you order
online. They do take your credit card information, but you are not charged for 30 days. Return the product any time during the 30 days and you are not
charged. So really nothing to lose. Try it before you buy it. We recommend taking advantage of the free 30-Day trial of the Magic Jack.
