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...

900/2100 MHz
Up to 2 Mbps upload and 7.2 Mbps download speeds
Quad-band GSM/GPRS/EDGE:
850/900/1800/1900 MHz
(Band frequency, HSPA availability, and data speed are
operator dependen)

exchange your phone for cash
exchange that cash for a phone that supports the correct bands.
curious to know if any of you guys have your my touch slide on ATT network?
Thanks.
No one has this on AT&T yet?
It just barely released on on T-Mobile. A lot of people aren't willing to pay $430 for a phone if they can't get 3G on it, and the rest are stuck in a T-Mobile contract.
ooh, so they can't get 3g if it's on the ATT network? 430? I've seen tons of them go for 380's, some unlocked as well.
Well, if it doesn't get 3g, I guess it helped me make my mind up to go with the Nexus One.
Thanks
my tmobile - my touch slide unlocked
Got my tmobile - my touch slide unlocked - but it wont get 3G on ATT - is there any way around this issue? is it a matter of the frequencies or what? perhaps someone can explain...
tmobile and at&t are on two different 3g frequencies. A quick google finds this information.
according to info i found on the net:
"In the U.S., T-Mobile and AT&T both use GSM technologies, but there are fundamental incompatibilities in their 3G services. AT&T runs its 2G and 3G services at 850 and 1900 MHz. T-Mobile's 3G service uses 2100 MHz to transmit and 1700 MHz to receive. "
Yet the htc my touch slide supports the following:
Frequency Bands GSM: 850, 900, 1800, 1900
UMTS: 2100
so should work unless article is incorrect -- can someone post the att and tmobile frequencies?

Just with the G1 and mytouch, these phones are specified to use certain bands for 3G and certain bands for edge/2G. This is a Hardware thing. It can support GSM: 850, 900, 1800, 1900 UMTS: 2100, (and 1700 I assume should be in there since tmobile uses 1700 for 3G) But the hardware is built to use ONLY 1700-2100 for 3g.

Could you let us know where you got it unlocked and for how much? There are two phone companies in Canada - Mobilicity and WIND Mobile - who have the same 3G frequencies as T-Mo but no Android phones! And we would love to know where to unlock the MT3G Slide. Thanks!

I have seen plenty that are unlocked and for sale on eBay for roughly 380ish
Can anyone confirm that a particular web site's unlock code worked for the MT3G Slide?
why would you unlock it to use it on a inferior network? especially because 3g will not work EVER! the phones frequencies do not support att 3g

I can't speak for the AT&T poster's intentions, but *Canadians* would unlock it to use the phone on WIND Mobile, Mobilicity and soon Vidéotron, which are all AWS carriers. This is why I'm trying to find out where to unlock the phone successfully.
Ebay it man, they're going unlocked there for about the same as new/no contract at tmobile
http://cgi.ebay.com/NEW-Sealed-Blac...Cell_Phones&hash=item3cadeffd9b#ht_500wt_1154
Well I figure I'd rather personally know where it came from and unlock it myself. =)
I got my mytouch slide unlocked by blowfish. Email him at [email protected] it cost me $10.50 to get my phone unlocked.

I'm using the slide on a regional carrier that uses the same 3g frequencies as t-mobile. Just because the other major US players don't use the same ones doesn't mean no one else does.
I used cellunlock.net, with 50% off coupon (easy to google, there are lots of them), it was only $10, got the code in 2 hours both times.
Anyone here have the galaxy s 9000 euro version working with tmobile 3 g in usa?
I'm also interested in that. I'm about to buy a galaxy here in EU but I'm moving to california soon. There should be no issues however since the galaxy is a quad band phone
I looked into importing a HTC Desire from Tmo UK for use here on Tmo's US network -
Tmo europe uses 2100 band for 3g, Tmo US uses the AWS IV band (1700/2100) for 3G - i did a little more research and found that 2100 was the download side and 1700 for upload - and as Tmo here in the US told me my Tmo MyTouch 3G would work fine in europe, i figured i'd be good to go - maybe only have 3G speeds on the download side
got hold of a 2nd level tech at Tmo and he 'xplained it down't work that way - if the Tmo US network doesn't see both freqs (1700 & 2100) it will switch me to 2G data speeds
so answer is, it'll work for phone calls, but data speeds will be limited to 2G

I can confirm, I did a lot of digging myself and found the same thing. I'm from the UK but living in the US for a year or so. I was going to get a Galaxy S from ebay but realised they didn't have the 1700 freq so wouldn't get 3g with T-mobile over here ion the US.
My Iphone 3g from the UK only gets edge data transfer speeds here in the US as it too is missing the important 1700 freq...

One thing I'm wondering is if it is possible to flash the android radio version from a Vibrant on to an international Galaxy S to enable Tmobile AWS?
that question is best answered by someone far more knowledgeable than i am in software and android OS
i want 3g
I just recently bought the unlocked galaxy s to use for when I study abroad in Germany in the coming months. However, I am experiencing the very issue raised in this thread and have been searching high and low to find a solution to change the radio frequency to include both 1700 and 2100. Hopefully, flashing the firmware from the vibrant to the unlocked galaxy s will work, but I'm not experienced enough to even know where to start.
Hi All
I have recently moved to Canada with my UK HTC HD2.
Since moving here I have changed my phone provider to Fido (Rogers Network). Internet seems extremely slow compared to my UK provider.
Someone told me that because I have a UK phone it is not using the correct bands for HSPA and that's why my internet access is so slow. Internet access is extremely fast on Wi-Fi so I know it's not a problem with the ROM etc.
Can anyone give me any ideas if this sounds correct - do I need to sell my UK HTC HD2 and purchase an American one to get over this problem?
Thanks
I think your friend is correct.
Rogers uses 850Mhz and 1900 Mhz, while in the
United Kingdom the bands used are 800Mhz and 1800Mhz (and some 2100Mhz),
Your UK HD2 is of European configuration, and should be able to cope with the Rogers frequencies. (See)
Your phone uses 900 - 2100 for 3G
Rogers provides it at 850 - 1900 , therefore your phone will slow down to GPRS speeds.
Have you tried flashing a new radio ROM?
If so, perhaps you should try another one.
At least in theory you could keep your phone and have mobile broadband.
What your friend is telling is true for dual band phones, however the HD2 is quad band..... Perhaps contact your provider (sometimes the dataplan has not been correctly activated, therefore access to mobile broadband is denied, and you will revert to the low GSM data band)
Otherwise contact HTC.
PS: Sorry for my ****-up
the t8585 (regular hd2) uses 900 and 2100 for 3g.
source
thats why canadian users with cash to splash go for the australian telstra model which uses 850/2100
You will only get GPRS and edge speeds, and no, the american wont get 3g either.
Yep....
I's official, I am cross-eyed, got the correct info, but wrong interpretation.
I stand corrected.
Thanks to both of you for the response .... I'm a little confused though!
So if I bought a T-Mobile USA model - that wouldn't give me 3G on the Rogers network I'm on? I have to buy an Australian Telstra model to get 3G?
Thanks!
*EDIT* ... Oh I think I get it now... I don't need to have the 850 and 1900 bands to use 3G on the Rogers network so long as I have one or the other - correct me if I am wrong please?
yea thats it, and the US hd2 has 1700/2100 which is why that one doesnt get 3g on rogers.
I get ya! Thanks for that.... so is Canada the only country that uses 1900? I'm asking because I now know that I can buy an Australian phone to suit the 850 but is there another country's phone apart from Canada that will use the 1900 band?
also I noticed something in my phone settings....there's an option to change my base band so I have selected 850/1900 GSM but it doesn't seem to have made a great deal of difference even after a reset
that's gsm, (calls, gprs and edge) nothing to do with the umts bands.
put umts bands into google, theres a Wikipedia page tells you what countries and networks use what bands.
Anyone getting the T-Mobile version tomorrow? With CDMA not SIM capable, and AT&T version still up in the air, I think I'm probably going to get one tomorrow!
I've got question regarding T-Mobile's werid 3G band tho. I think Samsung listed T-Mobile's version as AWS 1700/2100. I know 1700 is weird, but is that AWS 2100 same as the 2100 band that the rest of the world use? Sorry it's my first 3G T-mobile device, and looking on wiki or google is just kinda vague
2100MHz is the band used all across Europe as well as large parts of Asia.
So, yes, the T-Mobile one should give you 3G capability in other parts of the world, though if it's locked that may open up other issues.

I had a TMo US G1, and it worked fine on 3G when I returned to the UK. The converse was not true of my TMo UK G2 (HTC Hero), which would only get Edge in the US because it did not support both bands of AWS (1700/2100).
So, I see no reason why a TMo US shouldn't work pretty much everywhere else in the world where 2100 3G is ubiquitous.

Dave
Cool thanks, i guess that AWS threw me off. I thought there were a regular 2100, and then T-Mobile's AWS 2100

Actually you're a bit off. Tmo's 3G runs on AWS 1700/2100 band which is not the same 2100 *frequency* as the rest of the world. Tmo uses 1700 for downloads and 2100 for uploads, so both bands (aws/band IV) are needed.
Now Europe (and rest of GSM world) use straight 2100 band for 3G but the exact frequency is not the same as Tmo's.
Basically a Tmo Galaxy Tab will only get you EDGE outside of the US. An ATT Galaxy Tab will get you 3G in the US and the rest of the world (as long as it's sim unlocked, ofcourse).

No, the T-mobile phones give you also 3G in Europe. All AWS chipsets do both Band I (2100) and Band IV (AWS 1700/2100).
I thought the galaxy tab is quad band, so you can simply swap your sim card with another european carrier and it should work on thier frequency
Am I wrong?

You're right for 2G, not for 3G
So getting the unlock code for tmobile device and putting AT&T sim card will not give me 3g connectivity (using AT&T network)?

One could say the same to you.
This is a link to T-Mobile US's support forum, in which someone has had it confirmed from T-Mobile themselves that all devices designed for their network have to be fully compatible with the 2100MHz band, meaning they will give you 3G capabilities in Europe.
Your previous post in which you claim that the 2100MHz band that T-Mobile use is not the same as the 2100MHz band the rest of the world uses is nothing short of ridiculous.
If the band T-Mobile used was different to the one used in the rest of the world, it would not be described as 2100MHz.

Sorry, but as I already said earlier in this thread, my T-Mobile US G1, which is an AWS device, worked perfectly well in the UK with full 3G. Similarly, I know of people who bought TMo Nexus Ones in the US, and these all worked fine in the UK.
That's not to say there isn't some subtle difference which not all chipsets can cater for, but it is certainly true that many TMo US handsets will give 3G capabilities in Europe.

Dave
The normal UMTS 2100 is called "Band I" and t-mobile's AWS is called "Band IV":
http://en.wikipedia.org/wiki/UMTS_frequency_bands
The AWS 3G module has already 2100MHz support, so there is no additional hardware necessary to support Band I as well. Theoretically it could be disabled, of course, but then T-mobile wouldn't be able to charge you an arm and a leg if you were to roam outside of the US
