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

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.

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!

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

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.

Quad Band HSDPA/3G i9000

I was wondering if there is someone or somewheres you can puchase the Samsung Galaxy S which has a UMTS/3g 850/900/1900/2100 and unlocked.
I currently run on AT&T in the US and want to get rid of the US version of SGS and get a unlock/quad band version of this phone. I seen couple online stating that its Quad Band 3G/HSDPA. I wasn't sure if this model was out. I know its a Quad band GSM. I seen alot of tri-band but i run on ATT which runs HSDPA 850 so Tri-Band model will not work.
If someone has any info, please let me know. Thanks.

the international verison (i9000) runs UMTS/3.5G on 1900/2100 in america, since the 900 band is currently not in use by America
the i9000 doesn't have the 850 band, only the local AT&T, Bell, whatever is local to you have the 850 band, but they are all locked

Bell's Vibrant is tri-band HSDPA!

Alright, I saw it on the box, so I can confirm with certainty: Bell's Vibrant is tri-band HSDPA 850/1900/2100. I think I'm gonna get me one right away. (Might it be smarter to wait for deals from FS?)
Before seeing it on the box, noone could confirm that: I had called Bell tech support (highest tier), Samsung Canada tech. support, noone! I just can't believe how incompetent these guys (and gals) can be! Samsung tech support didn't even know what HSDPA is! Go figure! Who pays these guys?

yes 3 band data as mentioned above
and quad band voice 850/900/1800/1900
who cares about the voice, the 850/1900/2100 range is what we wanted anyways
now i can go to Brazil visit my >beeep< or go to europe and still have good data reception (using local sim cards of course)

Is the bell's vibrant different from t-mobile's???

Yes, it's a full-on I9000 complete with FFC and physical Home button.

confused about Bell's Vibrant 2G and 3G networks
For reference the Samsung I9000 Galaxy S has:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
What about Bell's Samsung GT-I9000M Galaxy S Vibrant? Which 2G Network? Which 3G Network?
I'm asking that because I'm confused:

Is it like AT&T's (and supposedly Rogers') Samsung i897 Captivate:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
Does that means Bell's SGS has GSM quad band built-in? But Bell's network is CDMA, not GSM?!
It's a pretty big deal if it has 2G GSM network compatibility, because as you said that means it's possible to use it with both European and Canadian cell phone carriers (once unlocked).
The 3G 850 / 1900 is necessary for Canada, and 2100 for France but that's assuming you stay in big cities where 3G networks are deployed. But what about going to the countryside? In that case we need to rely on the GSM 2G networks to get voice and data connection, am I right?

actually that's why for some people like myself the 850 is a pretty big deal, so that we can get 3G on the country side, otherwise we'll only get Edge or 2G

The 3G 900 in the specs must be wrong. Only Australia, New Zealand and maybe Iran use that band (src). And Future Shop is a sub-division of Best Buy so maybe that why they both have the same error?

So 3G 850 and 1900 are enough to cover cities and countryside for voice+data in Canada? There is no CDMA technology in the Bell Vibrant?
And we have a good 3G coverage for worldwide use thanks to the popularity of the 2100MHz band.
Some part of the countryside in France (including where my family lives) doesn't have 3G coverage. So I would like to know the 2G Network capabilities of the Bell Vibrant.
if it has Quad-band GSM then its only difference with the I9000 is the 850 3G band instead of the 900 3G band?! and the difference with the Samsung i897 Captivate is the external design and the front camera?
After additional google-ing I found an official news from Samsung (June 30th) that says:
The first Samsung Galaxy S™ device to launch in Canada will be the Samsung Galaxy S Vibrant™ and it is scheduled to launch this summer on Bell Mobility’s state-of-the-art HSPA+ network – the fastest and largest wireless high-speed network in Canada.
Canadian consumers can anticipate the release of additional Galaxy S™ smartphones throughout the rest of 2010.

So that means the Bell Vibrant doesn't relies on Bell's CDMA network, only on its HSPA+ network.
I see no point in waiting for Rogers to release the Captivate, unless we don't mind the lack of Front Facing Camera and prefer the other external design...

the Canada version of Vibrant operates at all those bands on both 2G and 3G also for Voice, so you got it all covered.
the only thing left is to get it unlocked after you buy it.
it is also compatible with the i9000 firmware upgrades without any changes

US T-Mobile's 3G freq vs the rest of the world?

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.
Regards,
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.
Regards,
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
