I know the geek term "least cost routing" is quite intimidating but it does not mean you should be afraid of it. Here's the short version why you need to learn this wonderful technology - save air time costs by up to 90% compared to standard rates.

Removing all the technical jargons, it is basically a system that automatically connects or redirects your outgoing calls to suppliers with the cheapest rate. By finding the most competitive rates in more than 500 suppliers worldwide, you will get significant savings both on local and long distance calls.

Don't think that because you're getting lower rates, you will also get poor voice call quality. On the contrary, least cost routing takes into account call quality when choosing the right supplier. You may not always get the cheapest rates but you will always get value for your money.

This is the system behind cellity's successful mobile applications called worldCALL for international calls and groupCALL for conference calls. Just download/install these apps from cellity and dial the number you want to call. By the way, you will need a GPRS connection before you can use these products.
