If I may suggest, and this is just my opinion when traveling to DR, is it absolutely necessary to have the latest and 'greatest' technology as a cell phone? I agree with all our users/posters, CDMA is getting phased out slowly and surely will become extinct eventually, but is it just a fad or is there a need for smartphones in DR? For myself personally being that I only use my cell phones to make calls on the island, I just dont have the need or itch to surf the web or use data for anything out there. If anything keep it simple, buy a phone in DR one that you know will work, use it for calls and texting. Luckily for me I have a blackberry that works both here in the states and has a SIM card that works when I use CLARO or ORANGE in DR.
I too am surprised how much CDMA is still being used in the USA. Sprint and Verizon are the largest carriers of CDMA phones and I dont see them dissapearing any time soon...

Sir/Madam,

CDMA is an "americas" thing. Europe and Asia NEVER had CDMA technology. I had my GSM Ericsson mobil with me to Colombia back in 1999 and could not understand why I could not roam. Went to Comcel (the biggest operator in Colombia at that time) and asked what is gloing on. Asked if I could buy a SIM fromt hem and the lady looked at me like if I had come from a far far away planet. I realised 5 years later when Digital mobile telefony were introduced in many South American countries that they used the US version of mobiles which I at the time had no frigging idea what was.

The new Digital system was.... Traa ta trataaa traaaaaaa (trompet fanfare) GSM

GSM is NOT a Smart phone thing but basicall any phone standard a part from a few places here and there. Now, the US has finally implemented GSM but of course they had to be different so all americas use 850Mhz and 1900Mhz frequencies where as Europe and Asia use 900 and 1800. Hence most mobiles of a decent quality are quad band mobiles.

GSM-900 and GSM-1800 are used in most parts of the world: Europe, Middle East, Africa, Australia, Oceania (and most of Asia). In South and Central America the following countries use the following:

Peru – GSM-1900
Costa Rica – GSM-1800
Brazil – GSM-850, 900, 1800 and 1900
Guatemala – GSM-850, GSM-900 and 1900
El Salvador – GSM-850, GSM-900 and 1900
Venezuela – GSM-850, GSM-900 and 1900

GSM-850 and GSM-1900 are used in Argentina, Brazil, Canada, the United States and many other countries in the Americas.

GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800 MHz band" (for simplification) when it was first allocated for AMPS in the United States in 1983.
The term Cellular is sometimes used to describe the 850 MHz band, because the original analog cellular mobile communication system was allocated in this spectrum.

GSM-1900 and GSM-850 are also used in most of South and Central America, and both Ecuador and Panama use GSM-850 exclusively (Note: Since November 2008, a Panamanian operator has begun to offer GSM-1900 service). Venezuela and Brazil use GSM-850 and GSM-900/1800 mixing the European and American bands. Some countries in the Americas use GSM-900 or GSM-1800, some others use three: GSM-850/900/1900, GSM-850/1800/1900, GSM-900/1800/1900 or GSM-850/900/1800. Soon some countries will use GSM-850/900/1800/1900 MHz like the Dominican Republic, Trinidad & Tobago and Venezuela.

In Brazil, the 1,900 MHz band is paired with 2,100 MHz to form the IMT-compliant 2,100 MHz band for 3G services.

The result is a mixture of usage in the Americas that requires travellers to confirm that the phones they have are compatible with the band of the networks at their destinations. Frequency compatibility problems can be avoided through the use of multi-band (tri-band or, especially, quad-band) phones.
