will the atom work on tmobile since its frequency is 1900 mhz?
Yes it does work I have Tmobile US.The rom has nothing to do with that,that´s the radio rom the one that handles,bluetooth,irda,wifi,network

Hi, I have an Audiovox SMT5600 but my network band is 900 MHz.
Can somebody tell me whether it is a hardware difference between SPV C500 (GSM 900 / 1800 / 1900) and Audiovox SMT5600 (GSM 850 / 1800 / 1900) or is it just the GSM Rom??? I have read the thread (http://forum.xda-developers.com/showthread.php?t=241435) which explains how to upload the QTEK rom, but it didn't work for me.
I have found the following explanation but it doesn't say whether it is hardware difference or just a different GSM rom.
"The SMT5600 is a tri-band phone that works on the 850/1800/1900MHz bands, which means it will work anywhere in the US where GSM service is available. In the US AT&T uses both the 850MHz and 1900MHz bands, as does Cingular. 1800MHz is used in Asia and somewhat in Europe, though Europe is mostly 900MHz. If you plan to travel to Europe, the SMT5600 should provide some coverage, but you might want to consider a quad band phone which adds 900MHz. The overseas versions of the SMT5600 (iMate SP3 and Orange C500) are triband world phones with 900/1800/1900 MHz coverage which means they'll work in Europe, Asia and in the US though you'll miss the 850MHz coverage used by AT&T/Cingular."
If changing a GSM Rom is the solution, where can I find the 900 MHz Rom and what is the procedure to flash it? Can I just use the Typhoon tools and perform an Emergency Flash for the GSM part or do I have to replace the complete ROM (like with mtty)?
Thanks in advance!
The radio freq's are hardware, not software to my knowlege. AT&T Cingular in the USA have moved to using the 850 MHz band for HSDPA data packets and 1900MHz for voice. Since the SMT5600 does not support HSDPA, therefore the low band is not used. If your market is 900MHz only, then your phone will not handle it. In essence you would need the European version of the iMate or Orange version. Otherwise, you are constrained to 1800 MHz.
OK, but then what about kamscam's explanation in the thread I mentioned above (http://forum.xda-developers.com/showthread.php?t=241435)? He claims that flashing the phone with the QTEK Rom will do the trick.

I have the iMate 2.4.33.11 ROM if you want to try it. I believe it is WM2003 OEM Rom for the SP3 (Typhoon).
If the claim is true that he changed an 850 MHz phone to 900 MHz and it worked, then this would seem to indicate that the phone may be Quadband but the Radio ROM only operates as Triband with the 1800/1900 always on and the 850/900 as selectable. This may be a possibility, but I still have my doubts. I still believe there is a different hardware radio for the 850 MHz and 900 MHz models.

There is hardware difference in C500 and STM5600 which runs on 850. Difference is in switchplexer which in European models filters 900 and 1800/1900 MHz (Murata HA 165) and in STM 5600 (Audiovox) filters 850 and 1800/1900 MHz (Murata HA 216AW). You have to change switchplexer on the board if you want 900 MHz on Audiovox
OK, I guess this concludes the story. I have actually suceeded in flashing a different GSM Rom (Qtek) but the phone still couldn't pick up the signal.
Thanks raskell and typakkk and everybody else for help!
I am very confused. my phone does not connect to 3g AT ALL.I have tmobile in usa in new york and I tried changing the settings in my phone options from gsm to wcdma and default the umts to 2100 and my phone stays on searching for service.. Can anyone help me out?? I want to be at 3g speeds not gprs... tmobile gprs is way too slow and it only works on GSM mode.. How do i connect to 3g with this phone? I updated my radio from 1.15 to 1.18 and I am getting the same exact results. This thing is driving me crazy, it just doesnt make sense.. someone please help me out, id greatly appreciate it
EDIT: Nevermind, i realized all of us HTC UNIVERSAL users are completely screwd because USA Supports only 1700-1900 Bands and the HTC UNIVERSAL only uses 2100mhz Bands.. NO 3G HTC UNIVERSAL IN THE USA. THIS SO SUCKS MAN.. =.-(

From what I have read on the Internet and speaking to a well knowledged person at a T-Mobile store the 1700 & 2100 AWS will be deployed in the United States. This is the same technology used in Europe on the 2100 UMTS WCDMA frequency. The T-Mobile representative had mentioned that New York City was using the 1700 AWS UMTS Frequency for voice & data but will also be deploying the 2100 Frequency later this year or early next year which last year T-Mobile was the highest bidder at the AWS auction and had also purchased this frequency but which originally the 2100 frequency was used by the government only for satellite transmission. Once the 2100 Frequency is deployed your radio will search for and if available find the 2100 frequency and connect to it automatically. You do not have to get a different sim card like AT&T which you have to purchase a 3G sim card. I am also anxious to get that frequency but is not yet available in my area. The best radio version is 1.15.
very very interesting... i cant wait till that comes then..

I disagree, usually with most software the higher the version number the better, and there is no evidence that 1.18 is any worse than 1.15 at all. I've been using 1.18 for around 1 year with no problems.
I was use a lot of times for search wcdma network name in shanghai , beijing or hongkong.
first , you need insert USIM card ,not SIM card to handset.USIM card is Support reg to WCDMA or GSM network.

You're post has been the most insightful writeup in regards to T-mobile US 3G I've ever came across, Many thanks!
Sorry if this doesn't go here but I have a question for the gurus from XDA, so here is the deal.
Recently in Costa Rica we got our 3G network released, but they chose HSDPA/WCDMA at 850 MHZ.
I was going to get an HD2 but due to it's bands I think I can't now. At some store they told me that it was possible to flash a different Radio version that will enable the 850 band.
I tought that the radio frequency was a hardware driven setting but I guess my question is if this is TRUE.
Can it be flashed to make it work
Thanks Gurus!!
Pura Vida.
Hello, I bought my unlock code on ebay for my AT&T Pure, great deal for under $4.00. I am using it with T-mobile U.S.A. but I don't seem to get 3G. Is that normal? (or is it like the G1 issue that doesn't get 3G on AT&T?)
Besides that, Is the T-mobile's HTC TouchPro2 rom compatible with the Pure? If so, how can I CID unlock my pure in order to accept the rom?
Thanks

You may want to try some different radios for your 3G issue.
As far as your ROM, a TP2 ROM would not work on a TD2, If you want to flash a TD2 ROM, I suggest reading the flashing guide on the Wiki for instructions on Hard SPL.
I see, but a touchpro2 rom won't work because I have to hard spl first? or because it is just no compatible? and also, where can I get a working radio for my 3g?
You will never get T-Mobile 3G on a Pure. It lacks the radio spectrum. AT&T and TMobile use different 3G frequency bands.
You cannot use a rom built from another device. A Rhodium rom won't flash on your Topaz rom.
You have an AT&T Specific device built for use on AT&T's network. You can flash other compatible RADIOS if you unlock it (which won't magically give you Tmobile 3G), but you'll brick your phone if you flash the wrong rom on it.
Maybe you can sell the Pure on ebay or craiglist and buy a Tmobile Rhodium.
"You can flash other compatible RADIOS if you unlock it (which won't magically give you Tmobile 3G), but you'll brick your phone if you flash the wrong rom on it."
so when you say that... is there a possibility that I can flash a compatible radio that wont brick my phone and get 3G?
No radio flash will solve your problem. TMO 3G compatibility is a hardware issue, not software problem you can solve.
There are plenty of TD2 ROMs here, so you should have enough selection. Make sure you do HSPL first before try any ROM.
T mobile uses 3g 1700
t mobile uses 3g 1700 frequency and at&t uses 3g 850 or 3g 1900
htc pure only supports 3g 850 and 3g 1900
I am trying to understand what the difference is between the frequencies that are used for 3G data for AT&T vs carriers like TMobile and Cincinnati Bell Wireless (CBW) and the specs I see on GSMArena such as "3G Network HSDPA 850 / 900 / 1900 / 2100".
Phone from Cincinnati Bell and TMobile are compatible on both networks as far as 3G data is concerned but neither apparently work with AT&T (and visa-versa).
If AT&T uses 850 or 1900 then that fits with the specs I reference above. If T Mobile uses 1700/2100 and requires both bands to work then I get why the above specs don't work as 1700 is missing. I think Cincinnati Bell is also 1700/2100 and assuming it required both I would understand.
I have a Samsung Galaxy S (aka vibrant) from CBW that is listed on GSMArena as "3G Network HSDPA 900 / 1900 / 2100" and for which operates on CBWs network as 3G. CBWs website advertises the phone as running 900/2100 which fits the specs as well.
I tried using an AT&T phone with specs "3G Network HSDPA 850 / 900 / 1900 / 2100" which I see as a "super set" of the Samsungs but can not get 3G. Is it possible that AT&T does something to lock out the 900 and 2100 since it does not use them and that somehow they can be turned on so the phone will work with another network?
hey,
im thinking about buying a t-mobile version of the G2 in the us.
but i thiunk its on the 1700 MHz. or is it also on the 2100MHz ?
because in germany i am on the eplus network and i dont know exactly on what band it is!
anyone having experience with that?
am i able to use the t-mobile g2 on the germany eplus 3G network?
thanks for your help
u should find some info about ur network's bands... if u cant , call them ... im with vodafone europ with tmous hd2 and its working fine with the 2100mhz 3g
Coming from the US, T-mobile has 1700/2100 mhz bands. I believe that means they use both
okay thanks,
i figured out that eplus has 2100 MHz and the phone im thinking about buying should have 1700 / 2100 MHz. so i guess itll work
thanks again!
Here's more footage on that:

The phone will definitely work in all GSM bands (Quadband) and the UMTS/3g Band 1700 MHz and 2100 MHz according to various internet sources.
