3G ATT (usa)?

not quite sure how to search this so i guess ill ask (or reask) the question.
1. am i able to reflash my Leo to work with USA ATT 3g bands if a rom ever comes out in the future?
2. can someone confirm to me if step #49 of this tips and tricks thread (http://forum.xda-developers.com/showthread.php?t=583638) and that piece of 3G activation software works and can allow my Leo to work with ATT 3g? (i dont think it does)
thanks!

1. Nope. It's all hardware.
2. See above. Nope.
It's all edge, my friend!

The HTC HD2 will not use 3g in the US. But since the phone is so fast, browsing the internet using edge is faster then with 3G on a sony X1a (my last phone).

do you already have an HD2? Regardless of anything you've read thus far, 3G is hardware dependent. No USA 3G internal radio? No USA 3G.
If you don't already have one, just wait until next month because the HD2 is supposedly coming to Telstra (who operates on 850mhz 3G, just like AT&T). HTC have said that the HD2 is coming in Q1 2010 but it's more than likely going toward T-Mo (based on leaked pics) or other carriers other than AT&T.

ah well i was under the impression that the hardware was both same for euro and us releases and just the software controlling it was different...(and how come they didnt name it the T8582 vs the T8585 as with the HD1 standard for the 2 different radios?....how they gonna distinguish the different hardware HD2s?)
come next year i may just sell mine for the new one (testra one you said). i dont suppose that tmo one will work with att 3g as its on a worldwide 3g band huh.
truly is a nice phone no doubt still

T-Mo US operates on 1700mhz AND 2100mhz for 3G (someone correct me if im wrong...one for uplink and the other for downlink). ATT can operate on 850mhz OR 1900mhz. The European version only has 900mhz and 2100mhz. As you can see, if you use the HD2 in the US (t-mo or ATT) right now, you're restricted to only EDGE unless they both possess their respective 3G bands.

this is what someone on htcforums.com said to me...confirm? deny? reject? love? i guess im just receiving conflicting info as to why this guy would believe this then?
"What you are asking about is a software differentiation. According to PDADB.net, the HD2 US version is scheduled for March 2010. http://pdadb.net/index.php?m=specs&id=2 ... us_htc_leo
The GSM version currently available is capable of T-Mobile US 3G frequencies; as T-Mo is the only US company to use WorldWide frequencies {2100MHz}. The version that is scheduled for March will be for AT&T frequencies. Since the hardware on these two versions are identical, you could flash a WorldWide version with a US version radio, & use a WW version with AT&T."

Your link doesnt work. I don't want to beat on a dead horse, but countless of T-Mo USA users have the HD2 and they could only have access to EDGE. Like I said, for T-Mo USA, their 3G has a split frequency (one for upload the other for download) that's why you need both 1700mhz and 2100mhz.

thats the link

this on HTC's site
Europe: Network Bands
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
which means it can work here no? since USA att 3G is 850 or 1900?

* HSPA/WCDMA: 900/2100 MHz <--3G
* GSM: 850/900/1800/1900 MHz <-- EDGE

Your problem is that you're looking at the voice/2G/EDGE bands. The HD2 is a quadband phone, so you can pretty much use it anywhere in the world. Your original question was regarding 3G, which the HD2 does not support here in the USA (yet).
3G would be this line HSPA/WCDMA. See how it's only support 900/2100mhz?

GSM is only voice correct? .... getting my voice/data abbreviations all mixed up...

GSM is voice and EDGE (data)

For ATT the key is 850mhz 3G as that what ATT has been adding, I don't believe they are doing any new 1900 towers. You can bing it there are lot's of articles about the iPhone congestion and changing/adding 850 towers. If we are lucky Telstra an, Australian carrier, will pick up the phone soon because they use the same 850 just like ATT. This is how people got the 3G on the HD(1) to work on ATT in the united states. HTCPedia posted a Telstra HD2 rom on Dec 9th, so hopefully they are close to releasing.

T-mobile's US HD2 works on 2100 MHz 3G in Europe?

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!

I did, check post #5

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!

My touch slide on att?

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!

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

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.

DHD, No North America?

Is it true that the Hardware of the DHD will not ALLOW 3G to work in NA?
I live in Canada and am craving to get the DHD but if it doesn't support 3G, it's not worth it.
Maybe Nexus 2 will be better.
Here is why i am asking, FCC information
http://www.engadget.com/2010/09/17/htc-desire-hd-hits-the-fcc-lacks-american-love/

Hi bteljuice. Maybe it doesn't allow that work in NA. But technology now a days are improving it might work on that.

It depend what frequencies your service provider uses.
The DHD supports
2G: 850, 900, 1,800, and 1,900 MHz (quad-band)
3G: 900 and 2,100 MHz (dual-band)
HSDPA (14.4 Mbit/s)
HSUPA (5.76 Mbit/s)
Also, i was under the impression that the HTC Inspire was the US version of the DHD

Basically, the American frequencies for 3G are different. I think that if I remember correctly, the best case scenario that you will have is 3G upload and 2G speeds.
It's these reasons, along with 4G, why the Inspire 4G is the Desire HD in the States.

Thread is old. Second poster never should have replied with useless info. Thread was before Telus DHD and inspire was released. Obviously they have been out for awhile now so this thread is dead.

HTC One updated frequency list

Hi guys! Thought I would put this here since I saw from the past few weeks about some people having signal issues with the HTC One.
Unfortunately HTC updated their HTC One page with the new frequency bands list.

Asia: 850/900/1900/2100 MHz with HSDPA up to 42 Mbps
Canada/ Latin America: 850/1900/2100 MHz up to HSDPA 42 Mbps
T-Mobile (US): 850/ AWS/1900/2100 MHz with HSDPA up to 42 Mbps
AT&T: 850/1900/2100 MHz with HSDPA up to 21 Mbps
Sprint: 1900/2100 MHz with HSDPA up to 14.4 Mbps
3G - CDMA:
800/1900 MHz for Sprint
4G - LTE:
Europe/ Middle East/ Africa: 800/1800/2600 MHz
Asia: 1800/2600 MHz
T-Mobile (US)/ AT&T/ Canada/ Latin America: 700 MHz and AWS band
Sprint: 1900 MHz

To the australian people who preordered their phones from EU. It is indeed official now that 850mhz is not supported.

*Australian on the 850MHz carrier here*
On one hand, I'm glad HTC acknowledged this and I've have been put out of my misery. On the other, I want to do a facepalm at HTC.
I understand how 850MHz testing of the European model could have been deprioritised. And I still believe HTC should be supported for coming out with a great phone at a time of trouble (possibly as many articles on their profit report as phone reviews!), but boy are they making it hard for themselves. They are not a new company. What's different about this phone vs the other internationally available in different variants phones they've released?
I have a quiet chuckle every so often about the saga of getting this phone. Excitement, delay, delay, worry about 850MHz support, dispatch!, oh what it won't work?!?, return, wait for local launch, to be continued...

You wouldn't happen to know what type of NFC it has?
Looked at GSM arena, no where does it go in to any depth on the NFC...
Cheers,

This HTC One® unlocked version comes with: 32GB of onboard memory and is SIM unlocked.

From my understanding this works in Europe too, except for the LTE?
Frequencies:
900 / 1800 MHz GSM, GPRS, EDGE
2100 MHz UMTS, HSDPA, HSPA+, DC-HSPA+
900 / 1800 MHz LTE
As I pretty don't much care about 4G/LTE the US unlocked will work otherwise without any problems, right?

Yes you are correct!
Other thank the UK variant not having 850mhz HSDPA frequency all bands from 2g to HSPA should be compatible worldwide.

It has the NXP PN544 chip with its usual level of support it seems. Unlike the S4, it should therefore support Mifare tags without issues.
