Some countries are just only now getting EvDO rev 0. They'll probably get 4G LTE when the developed world switches out their gear for whatever comes after 4G.
They'll also have to find spectrum for 4G since they're not transitioning to DTV like we are. Not difficult (4G can work on other spectrum, not just 700MHz) but it's something to consider.
EVDO? Which countries are you thinking of? The only major countries with CDMA that I can think of are the United States (has EvDO) Japan (using W-CDMA/UMTS for 3g, LTE for 4g) and Korea (going LTE)
DTV? »en.wikipedia.org/wiki/Digital_te···he_world almost every country in the world has begun or finished moving to Digital TV. -- "What makes us omniscient? Have we a record of omniscience? ...If we can't persuade nations with comparable values of the merit of our cause, we'd better reexamine our reasoning." -United States Secretary of Defense (1961-1968) Robert S. McNamara
I am referring to South and Central America and the Caribbean.
There are quite a few countries in the Americas who have CDMA/EVDO. Some have it for phone service, some have it for data only service (laptop cards primarily).
Of course in Europe and Asia they're all about GSM/UMTS and they have DTV transition covered, but I am talking about the Americas specifically.
But even if you include the rest of the world, a lot of countries have EVDO coverage:
