Bit confused with GSM/WCDMA in Galaxy S

---

I am seeing GSM/WCDMA in the network mode on my Galaxy S. Is this different from UMTS? I think GSM-UMTS is the right wording? I am in India.

in simple human non tech terms

WCDMA = UMTS = 3G = Data

GSM = voice

ok... my telcom operator website says hspa is faster than wcdma ...so wanted to cross check... thanks

Isn't it

WCDMA = UMTS = 3G Cell (voice + texts)

GSM = 2G Cell

HSPA = Data

I've had my phone connected as UMTS where I had no data but was sending and receiving texts. Although the most interesting of all is when instead of an H I had a G when Bell doesn't have a GSM network...

yes & no

you are right in some stuff, and that's how people gets confused by all the different techno terms

HSPA = 3.5G and it needs WCDMA for it to work



Text as in SMS doesn't need 3G, any GSM can do Text, but again that's complicating things

2G is better known as EDGE on marketing and Sales people talk, it's so uncommon to hear or see an advertisement say "blah blah blah and we offer 2G Data!" 0_o

there are more.... but anyways lets keep things simple
