Hallo to all!!
I'm looking for a T-Mobile MDA but I do not know if is a 900/.. or 800/.. and I would like to use in italy where we have only 800/... network.
I've just read the FAQ section but what do You think about compatibility?
Regards,
Simone
As far as I know Italy is in Europe.
In Europe there are 2 common GSM radio bands: 900MHz and 1800Mhz
The common GSM radio band in the US is 1900MHz
The MDA / XDA (Walaby) supports both 900 & 1800MHZ for sure
The MDAII / XDAII (Himalaya) supports all three bands for sure

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 read on GSMARENA that the 8525 us version is only 850 and 1900. is that true and is there any soft hack to put 2100 (I live in Brazil and 3g with TIM is 2100 here)
I think you read that wrong.
The 8525 already supports the 2100 frequency out of the box. Thats why it works in countries like Japan.
I belive what you were reading was the US (AT&T) uses 850/1900 for its network. However the phone itself supports GSM 850 / GSM 900 / GSM 1800 / GSM 1900 / WCDMA 850 / WCDMA 1900 / WCDMA 2100
Appears to be different version for US

It says (and I copy and paste)
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100
HSDPA 850 / 1900 - US version
Some phones have different versions for US
Every Cingular 8525, Cingular 8500 and ATT 8525 I've ever used (Mine and friends and work) have ALL supported the 2100 MHZ band.
I even searched the ATT HTC forums and all the results I've saw showed people using their 8525 in places like Japan that uses the 2100 freq without any problems. And these were all US versions.

Was in Japan last week & had no problems using my 8525 over there.
I used mine in 2100, and HSDPA work OK
Thanks for your answer

Thats the kind of answer I like to see here. Clear and objective.
(I would take of my hat to you but then it would show my bald head)
Any idea on how to get the HSDPA to work on the Cingular 8525? I have the AT&T Tilt and used the Kaiser Tweak and works perfectly. Co-worker has the 8525 but not showing up. We work about 300 feet from a cingular tower that has HSDPA because my Tilt picks it up but not his 8525.
Is there any type of setting that must be done for this to work like I had to do the Kaiser Tweak?
Thanks,
Flandrel
Among those of you with a deap knowledge of the inner working of HTC phone for 3G networks.
Is HTC doing something to phones for each carrier to lock the phone to a specific carriers 3G network and no other.
I'm asking because I was talking with a freind of mine who was given a HD2 as a part of a promotion for use on AT&T 3G network (850/2100). He uses T-Mobile and tried to get it to work with his T-Mobile SIM with no success. He also told me he had a conversation with someone from HTC that told him that he would no beable to get his HD2 to work on T-Mobile because the hardware will not work with T-Mobiles 3G network (1700/2100).
If this is the case does anyone know if it changable, is it a Firmware issue that can be changed or is it like hard wired physically?
Then the question is if we are buying these phone, some through contracts others outright, do we want to told whos service we have to use!!
Lets have some good discussion...
there are billions of threads on this.
3g is radio/hardware dependent. he'll unfortunately be stuck on EDGE.
He will have no issues using the phone with T-mobile usa. He will not get 3G because of the bands. He will just have edge. But calls, mms, text, email, and internet will all function properly.
Clarify this please
I bought my HTC HD2 in USA (unlocked) and here in Peru, where I live, I cannot get it to work with 3G. If I lived in USA, is there a way to know with what carrier I would get 3G ?

So you are on Claro in Peru?
For 3G you need a phone with 3G 1900 support. If it is the T-Mobile version, that would have 3G on 1700/2100 bands which would be no good. If you got an AT&T handset (850/1900) it would work for 3G for you.
You need to understand what 3G support your version of the phone has. For example mine (Telstra Australia) is 850/2100 - which would not be able to pick up 3G in your network - however it works excellent with Telstra (850) in Australia and currently working well with StarHub (2100) in Singapore.
Your phone is quad band - but that is GSM quadband not 3G - it is 3G dual band and that is what is important for your connection.

Hi tallmantim ....
Thanks for your response. Yeah, today I did my homework and found that my HD2 has UMTS (HSDPA) 900 - 2100 bands, a fact that is not good because Claro and Movistar in Peru operated the 850 - 1900 bands for 3G.
Question: is there a HD2 version with 850 - 1900 band ????

No, but the Telstra HD2 will pick up the 850MHz signals where they exist. There is no HD2 with the 1900MHz UMTS band at the moment

Would you mind pointing me in the direction of those BILLIONS of threads.
I've done searchs on hardware dependents, radio/hardware dependents, 3G radio.
There are so many way that is topic could be listed.
I'm finding nothing but my thread now just as before.

Erm, so AT&T gives a phone, for promotion of their service, and at the same time they should allow you to use another network? You've got too much hope there...

exchange your phone for cash
exchange that cash for a phone that supports the correct bands.
I'm goin to buy T-Mobile Unlocked HTC HD2 I just wondered if it will work in Israel even though its T-Mobile branded and unlocked
Our network band same as Europe
if that help i got SE W760i and it say on the screen signal "H"
You would have to know exactly what bands your carrier uses (there's several in use in Europe too), but even then the US T-Mobile HD2 probably won't get 3G service where you are, I believe that this is the only country that uses those specific bands for 3G. You could use the phone in your country, but it would only get EDGE speeds.
You would be better off getting the Euro version of the HD2.
after some research i found out that my operator uses this bands 850/2100
and in T-Mobile specs it says
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)
and another question if i wont 3g reception i get the "H" would it matter alot or only abit that i wouldnt be able to go through internet and stuff
Bump
Hello again i talked to my operator they said that the phone will work on HSPDA on 2100 or GSM 850
so which of the bands got the 3g on it
Thx
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:
http://forum.xda-developers.com/showthread.php?t=803035
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.
