is it possible to get an imported HSDPA phone to use it on cingular?? do i need to wrry abt bands?, or is it the same as edge, which is standard regardless of any country. lets say the imported HSDPA phone has 850/1900/1800

Must have WCDMA 850 / WCDMA 1900 to work in the States. Most unbranded phones are WCDMA 2100 which is useless.

isnt WCDMA jst 3G, HSDPA is 3.5G and it doesnt need to be on a specific band, im assuming hsdpa is universal, but im not sure

O'com on. You should know this. Just like EDGE was 2.75G it operates on the same bands as GSM/GPRS. You still have to have the right 3G bands for HSDPA to work. 850/1900 UMTS/3G/3.5G/WCDMA here in North America from Rogers/Cingular and 2100 in Europe, Japan, Middle East, Asia. When T-Mobile USA joins the 3G club this year with 2100/1700, it won't be compatible with the 2100 3G phones from abroad because of different up/downstream frequencies. So that will just add to the confusion.

Basically you've got GSM and WCDMA

GSM bands are 850/900/1800/1900. In the US, we use 850/1900. The other bands are worthless in North America.

GPRS and EDGE are simply the data side of GSM. You have to have the right GSM band for the EDGE on that band to work.

GPRS roughly equals dialup, EDGE is similar to the "advanced" dial-up speedbooster things.

WCDMA = UMTS = 3G

WCDMA channels voice and data the same, this is how you can have a voice call at the same time you're transferring data, and is one of the benefits over EV-DO (CDMA variant).

HSDPA is to UMTS what EDGE is to GPRS. It's the same thing, just a speed booster.

In Europe, their 3G is on the 2100 band.

In NA, our 3G is on 850/1900. These have no connection to the GSM bands of the same frequency.

T-mobile USA's 3G will someday launch on 2100, but they will use the 1700 upstream, which is different from Europe.

So to answer your question simply, in order to import an HSDPA phone and be able to use the 33G service on it, you'd need to have Cingular as your carrier and make sure the phone has HSDPA 850/1900. The only devices on the market with this is the HTC TyTn and the newly announced HTC Athena. Other than that, it won't work.

You forgot the new Palm 750, which has the WCDMA 850, 1900, and 2100 band.

Thanx, guess i got no choice, grrr... i knw abt this bands, dont wrry i jst ddnt knw if it applied to HSDPA too, ill get an HSDPA phone with video calling, the Cu500 seems like the only choice atm. Thanx!

Posted by: Rcadden

Note that the currently available CU500 does NOT support video calling. There's an update coming out (rumored to launch at the SUperbowl called the CU500v. That v is important if you want video calling. fyi.

Don't even dream about importing HSDPA phones yet. Maybe someday international phones will dare to include the US-compatible 3G bands for UMTS/HSDPA. But that's not happening anytime soon. The only way to enjoy 3G at this time is to get a Cingular branded 3G handset.
