How do I check the phone frequency/band?

I posted the same question to Diamond forum by mistake.
I want to know what 3G frequency/band (850 or 1900MHz) in being used.
Is there any software?

Field Test maybe?

I have it but what parameter should I check?
"Band" on GSM page shows "255: <unknown>".
What does it mean? How do I check for 3G, not GSM?

I have no clue

your phone needs to W-CDMA or UMTS capabale to support 3G. if you are using WM 6.1 it should also give you the option to automatically select Network type and GSM/UMTS band depending on the network you are in.
to check your options goto start-settings-Band tab- and look under network type and Band if you see WCDMA and UMTS settings there then your phone will use those when in a 3G network.
UMTS bands are typically 2100 or 1900+850
Again all of the above info is freely available on the internet..just google for 3G and you'll be well informed on the subject

Thanks, Prabh.
But I know the Band information tab in Phone setting and I selected;
Network type = Auto
GSM/UMTS band = GSM(1900+850)+UMTS(1900+850)
What I want to know is...Which frequency (1900 or 850) I am currently on.

I am going to switch over to Touch Diamond or Touch Pro.
US Diamond/Pro supports UMTS 850/1900MHz but I need UMTS2100 as well
because I often travel to Japan for biz trip.
I know UMTS1900 is widely operated in US but if my area (I live in NY) is in UMTS850
coverage, I will go for Aussie version which supports UMTS 850/2100MHz.

test individual umts bands

hello all, as of recently i own a x1a. and have already flashed to EnergyROM which is made for x1i. iwas hoping to find a program that can enable/disable individual umts bands to allow me to make sure both 850 and 1900 frequencies work.
n

no 3g signal

I hope someone can help me or at least point me in the right direction.
Im in the Philippines and my g1 is unlocked/rooted with the latest cyanogen rom 4.2.6.
The network im connecting to is smart communications with according to http://en.wikipedia.org/wiki/Mobile_network_code has:
515 03 Smart Gold Smart Communications Inc Operational GSM 900 / 1800; UMTS 850 / 2100
our phones have Modes GSM 850 / GSM 900 / GSM 1800 / GSM 1900
WCDMA 1700 / WCDMA 2100
So i should be getting a 3g signal or something but im not, my phone is not even making an attempt to connect to 3g. I have checked the settings and i cant find where to enable 3g. Use only 2g network is not checked. my apn settings seems to be correct but its not even getting to the point where it tries to connect to 3g. I have no 3g symble or edge symbol. please help..

help someone pls

sticking to 850 only

Is there any way to get my Captivate to stick to 850 band only, and not switch to 1900. I live in an area where I have 3G coverage on both bands.
Edit: I can get to this using SGS tools, but that would be only till a restart. Any way to get this to stick permanently until disabled.

Go to the phone dialer and put in *#2263# from there you can select what band you want. To check if it took, type *#0011#

Yes.. what he posted above should work even after reboot

The moment I set to 850 its switching from 3g to edge. Strange. Cos when on 3g mode its always been on 850, atleast 80% of times
Sent from my SAMSUNG-SGH-I897 using XDA App

Thats one thing the bugged me is that this phone ... AT&T version anyways.... loves to camp on 1900mhz more and would be fine if it would switch to 850 when needed..... alot of time I would be at -111db and still on 1900 when 850 in the same are would be at -103db.
I enable 850 that way but once you reboot... you need to do it again.....

Technically, the lower band should have lower signal strength reducing radiation. Plus should be using less battery power. That is why I am seeing how to get to 850.
Anyways, I think I'll leave it how it is.
