Does anyone know anything about this? Apparently it's been in use in the USA and UK for some time. It's just being introduced in Spain and I wondered whether it's any good. I only need a phone for emergencies. I had a Spanish SIM which needed topping up every three months which I eventually let die as I never used it. I'm currently carrying a phone with a Vodaphone chip in it just to use if really needed. Cost a fortune when Martin was in the hospital two weeks ago, but worth it to communicate. If I can find something more suitable it would be better.
