Here's one that promises to unleash you from your crappy phone that goes on strike once you are out of your country. Designed by Vadim Kibardin, the conceptual "Freedom Phone" is a small pre-paid handset that theoretically allows you to chat for 60, 100, or 200 minutes. There's no room for a SIM card so you'd be spared roaming charges.
According to Yanko Design, the Freedom Phone would charge in just 10 minutes. Not bad for a concept, but it should just stay as that. It's probably a better idea to buy a local calling card, though we might still consider using the phone as a paperweight.
