[QUERY] :--->WCDMA concepts and sim card availabilty .

          Can I use CDMA sim card in wcdma mobile phone? - Yahoo! Answers India

in my HTC One V I get GSM & WCDMA option
and Vodafone has WCDMA support

basically WCDMA is just a technical name for a 3g standard.there is no such thing as WCDMA sim & all 3g networks support WCDMA.

@OP: Don't get confused with WCDMA technical term...just test a 3G service & it will work.
initially I was confused when I saw the 'H' signal instead of '3G' in status bar..but it's actually 3G only

That means,whitestar, that my "AIRCEL" 3G sim card can also function as WCDMA under a specific device that supports it.
