Not sure if this has been mentioned or not, Magic Jack! If you're already in the UK, then you'll need to have someone in the U.S. buy them and set them up, don't fall for the pay for 3 years service now schpell they try, if someone is setting it up for you they'll need to register it to an email address, it can be yours that way you can get your call waiting. My MIL lives in Wincanton, she only uses cell phones so the extra fees we were being charged for them to talk was outrageous, so we set up two magic jacks one for my wife and one for my mil, (we don't have a landline either and only use our cells for home phone) you'll get a number for whatever area code the person setting it up has, so once you get it and plug it in, you can call any landline free, cell phones free though it comes off their minutes. And all this for $30 each once a year...one phone call to my mil paid for them both. The only thing we've ran into that was a down side is for some reason my mil doesn't have unlimited internet, so once she's reached her limits then that's it, no phone calls till the next month. Hope this help all, this beats vonage, skype is cool because you can see the other person, but magic jack has been a life saver for us., when we finally make our move to the UK we'll be able to use it to call my family here in the states too.
