Sorry I couldn't find a larger map. Maybe someone can figure out how to enlarge it. I'll see if I can find a big, better one.
The map gives you an idea of how widespread CDMA is growing. Only a few short years ago, it was in the US only and few other places. No CDMA in Europe because of course, CDMA (or competing technologies) is still illegal there for the most part. Otherwise the grey shows that both GSM/CDMA coexist. Not that Africa is still dominated by GSM, there's probably as much GSM there as it is POTS or plain old telephone service. South of the border, CDMA rocks.
Right now today, you can take your Sprint phone to about 40 countries. No sim card needed.

If you use any other regular Sprint phone or Verizon phone, the ones without the sim cards, your number of country choices are decreased to around 40. That's 40 places that have CDMA roaming agreements with Sprint and/or Verizon. That number is growing; one day it will be practically everywhere. So today if you go to New Zealand, S. Korea, or Hong Kong, you can pull out your Sprint phone and make the [expensive] call....

The Samsung World phone from Sprint is unlocked, so have fun.

Maybe it's a billing/logistical thing?
Who knows....
