Hi!
Does anyone know, what is the working frequency of 3G (WCDMA / UMTS)?
As we all know GSM has 3 frequencies: 900, 1800 and 1900 MHz. Plus one newcomer in family of GSM: 850 Mhz.

But what about SonyEricsson Z1010? Which 3G frequency this phone use? 1900? 2100? Both?
When new GSM-phone goes on market, there are always information that phone works 900/1800 MHz (and 1900 MHz). But when new 3G phone will be available there no information about frequency.

Just got answer from SonyEricsson Customer Care Center:
WCDMA uses the frequency range TX: 1920-1980 Mhz and RX: 2110 - 2170 Mhz.

So does that mean that the z1010 will be able to use all of the frequencies for WCDMA ?

Ive bin told the asia 3g network fones dont work with european 3g networks. So theres 2 'bands' for you. Add the usa cock up of spliting their 3g band and uve got 3 different 3g bands. Its gsm all over again!

Seems that there are only one 3G freguency -- as SonyEricsson says about Z1010:
Tx stands for Transmitter and Rx stands for Receiver, so naturally both frequencies are supported. A phone always has both Tx and Rx values.
