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.
