Is the need for an "International" SIM Card ending?

Many restaurants now post a WiFI logo card in their window. Some are open, some you have to get the security code from them.

Wifi is great, but it is less good for incoming calls. Many of us carry cell phones largely for emergencies, but you can't count on being in wifi range when an emergency strikes. On my last trip I carried a cheap little phone using OneSimCard, which offers an email-to-sms gateway. That way, non-emergency callers could text me for free, and I could then return the call from my iPhone when I had wifi.
