Rebtel is an international calling service that assigns your international contacts a local telephone number and then charges you lower rates (than regular long distance) for the call. It takes the confusion out of dialing a million numbers or worrying about calling cards to make international calls. It’s actually a pretty unique service and one I’d consider if I didn’t have access to Skype.What’s most important is that they are currently offering 792 US Airways miles for simply signing up for their free service. It takes about 2 minutes (or less) in total:First, go to the US Airways Dividend Miles SkyMall here and login with your Dividend Miles number.Once logged in, do a search for Rebtel and click on the “Save up to 90%…” link.Then just click sign-up and you are good to go.I really like US Airways and I conservatively value 792 miles at about $15, so I think this is a great deal for such a short time requirement.
