Very soon your mobile phones can be used for making free calls over the internet. It is no magic, but it is the device unveiled by MagicJack recently that makes it possible. It is a plug-and-play VoIP device that allows the mobile phones or smartphones to access the internet through MagicJack Voice Network to make calls. So, you are no longer making a call to any location of the world through your call carrier network.

The device of MagicJack is simple plug and play femtocell technology and it is the smallest and probably the cheapest in the telecommunication industry. The device is compatible with almost all cell phones and also with any service providers.

Coming at a cost of just $20 a year, this device will help you save thousands each year in your mobile bill. In fact the savings are much high if compared to international calling made through your call carrier network.

This device of MagicJack uses the wireless spectrum in connecting your cell phone to the USB device. Since the wireless spectrum is not owned inside anyone’s homes, so they can easily slip through all the legal loopholes and use the spectrum. In simple words, the MagicJack’s femtocell bypasses mobile operators completely. This device can be used with any GSM cell phones and on any band, even locked mobile phones. The range of femtocell is 3,000-square-foot.

The MagicJack device is a USB connector of the size of matchbox that plugs into the computer. It loads software onto it and it makes use of the computer power, processor and broadband connection. It uses the computer to make calls but with the cell phone and not with wired phones.

MagicJack is a subsidiary of YMax, a private company. Two years before it launched a call making device through internet named MagicJack and since then have sold over 5 million of it through retail stores like Walmart, Best Buy and RadioShack. The company claims the quality of it better than Skype.
