USD may be the most ubiquitous currency on the planet. However, go visit a country like Japan. Once you're out of reach of any currency exchange, you won't have much luck using your USD. Ironically, you'll have better luck using a Visa/Mastercard (which, btw, are not used anywhere other than perhaps ATMs). Those credit cards require a network to be used.
I've been to Internet cafes in Japan. But I never bought a single thing with USD. I don't see Bitcoin having any issues here. Internet is more widely available than places that take whatever your paper currency is.
You can easily take Bitcoin with you. You take your credit card with you. Both require electronic communication to work. There is no difference here.
