Onesuite.com is a long distance provider where you can use it either as a phone card or a voip service.

Rates are very competitive and there are access numbers in more than a couple of dozens countries around the world. So if you are in China or U.K. for example then you can still use its phone card service for calling any country in the world.

Voip service is another service they offer where you can use the same account. So most prolly we are all familiar on voip concept so no need to explain what voip is.

Everything can be done online (recharging, checking call history, changing details, etc) and accepted form of payments are Paypal, Mastercard and Visa.

I saved a lot using Onesuite compared when I still use my local phone provider for making long distance calls.
