The genrals bands supported by phone are 

UMTS / HSDPA / HSUPA devices operate in the UMTS frequency 
bands 800/850/1900/2100 or 850/1700/1900/2100 MHz:

2100 (downlink) / 1900 (uplink) for Europe, Africa, 
Australia, New Zealand, Asia (including South Korea and 
Japan) and Brazil (usually referred simply as UMTS2100)
1900 for North and South America
2100 (downlink) / 1700 (uplink) for T-Mobile USA and 
others, called AWS Band (usually referred simply as 
UMTS1700)
900 for Australia (Optus and Vodafone Australia in rural 
areas) and in the future in countries that currently use 
GSM900
850 for North and South America, Australia (NextG), New 
Zealand (Telecom)
800 for Japan (NTT DoCoMo in rural areas)
Note that being UMTS / HSDPA / HSUPA quad band doesn't mean 
that phone is a GSM / GPRS / EDGE quad band. However nearly 
all HSUPA quad band devices are EDGE quad band too.

Five and Six band phones (800/850/900/1700/1900/2100) are 
possible but none have been announced.



1st way to find: go to UI settings of BAND SETTING and 
check the bands avaliable to select which gives the details 
about the bands supported byy the phone.

2nd way to find: if there is no options to view the band 
settings then 
we can connect the phone to the simultor and check if the 
phone if phone latches to the network at that band.

as there are hardly 10 bands which a phone can support 
using that we can ckeck the bands supported by the phone 
with the help of simulator.


3rd way to find:
go to QXDM -> static message (there is a hot key for that, 
but i dont recollect), go to View->and check for static 
message. There you should be able to check the bands which 
mobile device supports.


and there are many other ways by which we can check the 
band settings.
