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...

yea my friend my phone is , and i am here with t mobile suffering from same problem like u , i bought that phone which is compatible with Asia , not here in usa
is there way to exchange??
mine is
Network HSPA/WCDMA:
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.
Hi,
The official specs of T-mobile's HD2 says that the supported 3G bands are: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Does it mean it will work on European 2100 MHz 3G too? Nexus one does so I suspect HD2 could too but as far as I could digg nobody had a straight answer to this question yet.
-AlefSin
actually i asked HTC CS before, and the answer is NO!
european countries WCDMA frequencies are the same with ASIAN countries. So no chance for European countries either.
hmmm I don't know JohnQ. In your attached email HTC is saying China's frequencies are different from the rest of the world so how do you say it's the same as Europe? I don't know much about 3G network in China though.
Just a few weeks back it was annoounced that the US operators had all signed up to migrating to the rest of the wold's GSM standards!
So in time we will all be singing from the same hymn sheet!
Accoridng to Wikipedia, while 3G in China is using the same frequencies as Europe in UMTS-I band, the air interface is different (TD-SCDMA vs TD-CDMA).
(sorry, cannot link to the docs since as junior member cannot embed links yet).

Wow, that's... odd! It seems US operators cannot even agree whinin US and now they all want to use the rest of world's standards! That's so un-american!
At&T, rogers, etc are all using european 3G frequencies, which is why you can use device from europe on their networks.
T-mobile US uses 1700 & 2100 (one for up stream, one for downstream) which is why it won't work on at&t etc or european frequencies.
The t-mobile 3G phones use both 1700 and 2100 at the same time; and they cant use 2100 seperately on other networks.
erm att uses 850/1900,and very few operators use the same,none in Europe use these bands

I've tested mine on a 3G only network (2100mhz) and it works fine. What I mean by "only" is that the Digi Mobil in Romania works only on 2100Mhz.
I hope it helps!

Well, it seems the answer is negative. I asked HTC:
Hi, I'm very excited about HTC HD2 on T-Mobile USA. However there is a cruicial question taht I could not find an answer for yet: Should I get this phone, when I travel to Europe, can I use 3G? The specs say this phone will support AWS/2100 MHz UMTS. Since the 2100 MHz is the dominant frequency for western european 3G networks, does it mean this phone would work on their 3G networks? Nobody at T-mobile's support could answer me so I hope you could solve this mystery.

And they answered:
Thank you for contacting HTC Technical Assistance Center. I understand the importance in researching a phone before you purchase it. This is a unusual situation and one T-mobile may not have been experienced with. For T-mobiles network the phone will be using the 1700 and 2100 bands. Although the 2100 band is common world wide. allowing the phone to pick up the edge network. T-mobile uses the 1700 for there 3G services. This band as far as we are aware is only used by T-mobile when it comes to major carriers world wide. More then likely the phone would not be able to pick up 3g if taken over seas.
However. T-mobile dose have a few branches in Europe. You may wish to check with them to see what bands they use for 3G, and if they have had any conflicts with American phones.

But T-mobile's HD2 is not out yet! Are you sure you didn't test European HD2?
OK things are starting to get weird. I received a negative answer from HTC's customer support but then I found USA T-mobile G1 users that reported their phones were working on 2100 MHz 3G in Europe (G1 like US T-mobile version of HD2 only supports 1700/2100 MHz 3G). I need to buy a phone and these contradictory reports leave me confused
Here is what T-mobile says in the specs sheet of the new HD2:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

Isn't it interesting that 2100 Mhz is listed both separately and in with combintaion with 1700 Mhz?

nice email address you have in that picture John
I tested my unlocked TMOUS HD2 in Sweden using 3's network and worked like a charm in 3G
Bit of a bump here as I'm trying to use my unlocked US T-Mobile HD2 with Orange in France and I can't do better than Edge (it went down to GPRS at one point...). I guess it could come down to spotty reception but I do get 3G speeds in my current location with an iPhone 3GS so I'm not so sure...
I'm using the AmericanAndroid ROM, maybe that's why my speed is throttled ;-)
I am using HD2 T-mobile in Serbia and i have no problem with conection or data speed.
I was on vacation and i didnt use Wifi ,and i used the phone all the time on 3G - the 3G network is incredibly fast, I even think that it is twice as fast as the EU HD2, which I used before..
Thanks, will check again then, maybe bad reception then!
What is the difference between the two and can you make an "a" an "i"?
the differences are the 3g frequencies that they support
i forgot the exact bands but i know that the x10a supports us atnt, rogers canada, and telstra australia 3g bands. the x10i supports asia and european 3g bands
The difference is pronouncation. Also a is the first letter in the alphabet while i is the 9th. I don't think you can make i into a and vice versa.
PS. You can make [email protected] and vice versa but it causes SEUS problems.
x10i and x10a both have the same GSM network frequency as 850/900/1800/1900, or you can call as as Edge network as well. As for the 3G frequency or UMTS bandwidth, here is the difference:
x10i
UMTS: 900/1700/2100 MHz
it will support Asia / Europe / and T-Mobile USA 3G network.
X10a
UMTS: 800/850/1900/2100 MHz
like dorifuto.boi said, it will support AT&T US, Roger Canada, Teltra Australia. It also support Japanese Do-co-mo 3G network as well.
You may wanna check with your current service provider and ask them which UMTS bandwidth they fall into the above category. Again, this is for GSM network only. If you are using Sprint, Verizon, etc they are in differenet as they are in CDMA network.
To further add to your comments
SE uses the a or I for country variants
A - America's (Canada, US & Latin America) Support these bands
I - International (Europe, Asia, Middle east etc) support these bands
thanks for the info. I received and "a" as a gift, but am not able to get on tmobile3g. Only getting edge, but it runs fine.

Bell and Telus have 3G (only) networks in Canada in these bands
By the way... it is technically possible to build a phone that works on all the 3G bands, so that it would not be required an "a" and an "i" version?
the Nokia n8 is like that. 5 band 3g. but the x10 is not

Yes it is - for some weird reason t-mobile was included in the international version, and AT&T was on the American version... But the facts is, that both versions have 2100 MHz 3G which is the most used 3G band worldwide... As I see it, you will just have to go into a secret menu and then check off some other boxes, and then it should be able to use the other 3G bands!
I'll post an image...

just because they both have 2100 doesn't mean ATT and t-mobile are using them. personally they should have made 1 model with quad band 3g. better for everyone.

Telus supports 1900/850 MHz frequency bands. More detail at telusmobilityDOTcom/en/ON/network/about.shtm
BTW, AT&T and all other major Canadian providers use these bands.
Edge yes, 3G no
There are definitely a lot of people curious about whether they will release a rogers/AT&T band version. My guess is probably not, AT&T probably won't be interested in picking it up and it would be hard to justify it otherwise.
Ughh I really want to get one but no 3G on at&t is a dealbreaker

canada now has 3 providers using the AWS (1700) like T-Mobile. Wind, Mobilicity and (I may be wrong here) I believe Vidéotron
It will NOT work on Telus or Bell, period. It doesn't have the right 3G frequencies and Bellus doesn't have a GSM network.
Hi all, we have several friends who want to buy the Motorola Atrix in use and bring to spain know if it worked well here?
Thanks
It's all about frequency !! what frequency does your cellphone company operates with?
Atrix supports 850/900/1800/1900

all gsm phones right now are quad band so it will work anywhere.
The question is what 3g bands are supported in Spain. On Movistar Venezuela, 1900mhz is used for 3g, which the atrix supports. Find out what your provider uses.
