Hello to all
i have been searching a few known phone's that i like but i can't seem to find a phone that has gsm 2100 mhz band is this a new band on the gsm network thier for i have to wait for them to make gsm 2100 mhz band phone
Reason being i with tmobile and the 3g i been told by tmobile rep only works for tmobile on 2100Mhz gsm band
if possible is thier away to change or reprogram your phone for the band or is this hardware in the phone
sorry i'm quite ignorant to this network tower thing but trying to learn
thanks for you help
you might as well be going from analog to digital. its normally not just a software update.! its a complete hardware change. If you look at the iphone for example it has 3 radio chips in it all for different bands!

AT&T/Cingular are in the process of rolling out their HSDPA network and a handful of cities are using it; NOW is the Universal capable of this....I asked a similar question about the UMTS 1900 MHz being activated so it could be used in the states; Granted I was given some very good replies but I am still curious. Over the past week I have been talking to some other engineers in my field and have found that a great number of things are possible with the Universal, it has the architecture to support this, SUPPOSEDLY ! Now lets look at UMTS as a whole; then HSDPA ! HSDPA is a software upgrade to existing UMTS software, that's all ! SO is it possible that we can have HSDPA on the Universal with an upgrade to the radio stack, I think YES !...and the bands should also be able to be activate, current UMTS 2100 MHz to 1900 MHz so it becomes dual band...the other is the GSM 850 band ! That apparently can be activated !...HOW is the big questions....Most of the HTC is limited by software; not hardware...its existing hardware has been built with scalability in mind...I just hope that some one can figure out the radio stack updates to facilitate this functionality !
The current model does not support HSDPA. However, I heard that the HSDPA version is due before year-end.
Hi,
I am planning to buy Touch 3G or Touch Diamond. (Still confused)
However, can anyone tell me which one of these will work with US carriers 3G services.
The specs mention
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100 / 900
So, general latching on to US GSM networks and using Edge is not a problem, I know. However, not sure about 3G.
Whatever reading I have done shows that the 3G network is as per European standard. So I am sure I should be able to use 3G in Europe/Asia.
Can some gurus help me with this.
Appreciate your help
Anup
I have ATT, and no, the Touch 3G does not work because it is missing the 3G band used by ATT. I only get Edge in places where my old P3600 would get 3G.

Does this mean that this device will work at least for voice/SMS in Japan (which only has WCDMA 2100, no conventional GSM at all)?
Can somebody please explain GSM vs WCDMA vs UMTS for the bands?
My impression is GSM is 2G and UMTS is 3G and both can supply regular phone service? What's WCDMA then?
T-mobile USA is GSM 850/1900 and what else?
I was thinking if I specify what network and band to use it'll use less batter (ie. no 3g unless I really need it).
this is a really easy google search... or just go to wikipedia....really any search you would try will answer your question.
(you're half right, but mostly wrong)...here's some links for you

Well I did google already, but still is over my head when I look at the band settings in the TMO HD2.
If WCDMA = UMTS why is there a separate GSM/WCDMA network selection, both allowing bands in GSM and UMTS.
Sounds like GSM is older tech, meaning 2g, whereas 3g is the newer GSM, which is UMTS, which = WCDMA. Therefore, how can you choose UMTS band frequencies on a old GSM network?
Perhaps I'm not phrasing my question correctly. I'm asking these because of the phone settings. I'm trying to figure out if it's more efficient to just tell the phone to look for specific network/band for TMOUSA thereby saving time and battery.
is this just too simple of a question or not many people understand. anyone?
ok, instead of giving you a bunch of info, let me give you just what I think you need.
I'm guessing you're going to Settings>Wireless Controls> Phone>Band and that's where the confusion is coming from. This screen is wrong and the Bands listed there are wrong (they're from previous devices, and htc didn't bother to update that screen).
So, you have 3 main choices there that should be of interest to you as long as you're in the US on Tmobile's network: Auto, WCDMA, GSM (under Network Type).
Auto: switches automatically between GPRS/EDGE/3G (HSDPA, HSPDA+)
WCDMA: 3G (HSDPA, HSPDA+)
GSM: EDGE/GPRS
The only way that playing with the band frequencies could help you would be if you're just interested in Edge/GPRS since tmobile uses two different frequencies there (native 1900 and 850 roaming). For 3g however, Tmobile uses only (and concurrently....as in you need to use both to get 3g and not just one or the other) 1700/2100 frequency.
Long story short, if you're trying to keep the phone from switching between 3g and Edge and you're in an area that has constant 3g, set it to WCDMA. (but note that if you loose 3g but are in an area with Edge, it will not switch to Edge, it will just be 0 bars/reception).
thanks alot, that really clears it up. I don't have data connection besides mms so I figure I may set it to no 3g and save some battery.
I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks
I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.
Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900
Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.
Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.
Does anyone know if the Verizon Trophy will do CDMA on AWS with the correct PRL on any of the available radio software?
Also is there a app or a way to show cdma call info such as channel, PN, rssi?
http://www.microsoft.com/windowsphone/en-us/buy/7/details.aspx?id=1685
It says "HSPA:AWS 2100" and that is the GSM Trophy. I think its safe to assume that the Verizon model supports it as well + CDMA.. but.. well.. AWS is new one on me. I won't pretend to fully understand what your talking about. XD *haha* I better go do some reading.

AWS is advanced wireless services. It's the FCC name for the band of spectrum the 1700 and 2100mhz range.
What I'm not really sure about is if the same radio is used for both CDMA and HSPA. The phone can do AWS if using HSPA, but it uses the cellular and PCS bands for CDMA. (800 and 1900mhz)
The issue is that the radio need to be programmed for those bands and there is hardware needed to make it happen. So a phone programmed for 800mhz can't just switch to 2100mhz unless there is hardware present.
The Verizon version of the phone might just have an extra radio thrown into the case that operates seperatly from the GSM one. If that is the case then it wouldn't be possible to use CDMA on that frequency. If it's all tied into the same radio then it seems like it could be done in software. In either case I'm not sure if will ever happen because you'd probably need to write your own firmware to do so. (It really wouldn't make sense for HTC to waste time seeing if the phone would do CDMA on 2100 if it wasn't designed to)
For reference there is a great article covering the bands here:
http://www.phonescoop.com/articles/article.php?a=99
There is also the full version of the spectrum chart online here: http://www.ntia.doc.gov/files/ntia/publications/2003-allochrt.pdf
There is a dev screen you can get to on the phone to show signal strength and a few other options. If you dial ##634# you can select field trial. You can see Channel #, band class, Active Set Pilot PN, Rx Signal Strengh, Rx Power (dbm) under the EVDO screen. There is also a section for 1x and GPS. I'm not sure if another option shows up for HSPA if the phone is on GSM...
EDIT: The best I can tell is that AWS uses UMTS/WCDMA so the phone should support that. HSPDA is just a faster version of WCDMA so since the phone can do HSPDA on 2100mhz it would be able to slow down to WCDMA speeds. The only time I could see it possibly being an issue is if CDMA was being used on 2100mhz and not UMTS.
Only thing I am seeing inside of the newest Verizon Trophy software (mango v3 8107) is that they added support for CMAS.
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\ShortMsg\Settings]
"CmasOperatorEnabled"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\ShortMsg\Settings]
"CMASAlertOption"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\SMS\Broadcast]
"TestPort"=dword:4370
As for radio, there is only one radio software.. but from what I can tell, the CPU/radio has all the same support as the Trophy GSM, but with the added CDMA. AWS should work, but only via GSM bands.
