OneSuite can help you keep in touch while you travel

Hey all--
I am heading to London for the holiday to visit a friend and I just started using this company called OneSuite.com for international calls. Anyone out there used them yet?
I have used them from the states calling abroad and they just added the ability to call from other countries. My friend in England has been using their service to call me and it has always worked out really well (no echos). I used to buy calling cards per country I visited while traveling, but this time I am going to use OneSuite.
Just thought I would share a little knowledge because it is a cheap way to keep in contact when you are on the road---then when you make friends in another country you can talk to them when you are back in your home country for cheap arty:
