Is the Atrix 4G 3G tri-band 850/1900/2100 ?? - Atrix 4G General

Can anyone confirm if the ATT Atrix 4G supports tri-band 3g 850/1900/2100?
GSM arena states it supports all three frequencies
http://www.gsmarena.com/motorola_atrix_4g-3708.php
But both amazon and walmart list the 3g bands to only support 850/1900
I'm currently in hong kong and the primary 3g band is 2100 so this will definitely affect my decision to buy the phone outright.
anyone with the atrix overseas with input would also be greatly appreciated!
Thanks for your help!

Go to www motorola dot com/atrix there is tech specs it supports 2100.

It doesn't support 1700 though which is critical to functioning correctly on TMO's network....
Too bad, tmobile's 4g is much more widespread and reliable than AT&T. It's sad that from a 4G/data perspective, AT&T is by far the worst carrier.

(1) This is an old news, and there are already a few threads about it here.
(2) Your article is wrong.
AT&T uses 850 AND 1900 for 3G, so it will on AT&T's 3G network.
T-Mobile USA, however, uses BOTH 1700 and 2100. 2100 alone is not going to make it work. This phone will NOT work on T-mobile USA's 3G network.
2G will work on both network, same as the European/Asian verison, since it is quad band.

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

[Q] question for 3G frequencies in Canada

I have a tmobile vibrant phone (hardware only). According to the phone specs i SHOULD be able to get 3g signal with my fido sim card since the phone seems to support all the same frequencies as the Canadian i9000.... but i only get edge.
If you guys are getting 3G with fido or rogers sim cards, did you have to set anything special in the phone settings?
Thanks!
Vibrant T-mobile 3G runs on 1700
that is why you only get EDGE (2G)
Fido, Rogers & Bell runs on 850 & 1900 for 3G
On my way to work today this is what i saw in the network box.
inside my house - EDGE
Outside my house - 3G
back country roads to work - i saw just G or no signal (normal i loose signal with my iphone and blackberry on there)
at work - back on edge
So i DO get 3g somehow! or is it just teasing me by showing 3G?
i read somewhere that the t-mo vibrant does have 1900 as one of its 3g bands, so this is why your phone has been able to pick up 3g at times. the problem for you is that rogers/fido mainly use the 850 band. i had the nokia n97 mini that had the 1900 but no 850 and while driving around most of the gta i would get 3g, but when i went into buildings, houses, etc, it would drop to edge.
Maybe your phone supports 1900 and not 850 MHz? Or the oposite? That would explain why you would get bad UMTS coverage.
@hondaguy you were faster than me

To my knowledge the T-Mobile Vibrant does not support the major Canadian 3g bands. It is quad band 2g, which is why you are able to get edge but it is only 2 band 3g, at least according to this spec sheet:
http://pdadb.net/index.php?m=specs&id=2439&c=samsung_sgh-t959_galaxy_s_vibrant
T-mobile uses the 1700 and 2100 UMTS bands for 3g, Bell/Rogers/Telus/Virgin/Fido use 850/1900 UMTS bands for 3g. Therefore the 3g radio on the Vibrant is not compatible with these networks.
However, WIND mobile uses the 1700/2100 UMTS bands for 3g and you can use unlocked T-Mobile phones to their full ability on Wind's network. Wind is only in major urban centres though so this may not help you if you're not in the city. Hopefully you are as Wind has a pretty sweet unlimited data plan!
http://shop.windmobile.ca/
On the other hand according this this article from Engadget:
http://www.engadget.com/2010/08/22/confirmed-galaxy-s-unlock-codes-are-stored-in-your-phone-vibra/
If they're right that the Vibrant is somehow capable of AT&T 3g, it would mean the phone has to be tri-band UMTS: 850, 1700, 2100 (or 1700,1900,2100) as AT&T uses the 850/1900 bands like Rogers/Bell/Telus.
This doesn't make sense to me why T-Mobile would do this. The 850/1900 bands are really only used in North America on competing carriers, so it doesn't give the phone "world" capabilities, the 2100 band does that. Why they would add a feature who's only purpose is to make the phone work on competitors' networks is a mystery to me but Engadget seems to have a picture that confirms it. If this is true than an unlocked Vibrant should technically be able to work on Rogers/Bell/Telus/Fido/Virgin 3g, but only if it is unlocked. I'm pretty sure that T-Mobile sells their phones SIM locked to their network, have you unlocked yours?
~Edit if it does have 1900 as the third band the above posters are correct in that you will get minimal 3g coverage as 850 is the primary in Canada.
yeah i wanted to switch to Wind Mobile for the $35 true unlimited data plan, until i found out they don't work with normal 850/1900/2100 phones
only 1700 / 2100

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.

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

[Q] Which Network ????

Hi All
I am visiting the USA in September for holiday and am doing a bit of travelling while i am out there. I was going to buy a prepaid sim to use with my SGS II which is sim unlocked. I am visiting Los Angeles, San Francisco and Vegas what network would you guys recommend for coverage and costs ?? it would have to be a GSM network.
Thanks
I would say T-mobile because they have a awesome pay as you go plan
I would say T-Mobile
T-Mobile and AT&T are the only ones compatible with your SIM. However the SGS2 is only going to get EDGE on T-Mobile if you're wanting data. It's compatible with the HSPA for AT&T however. From what I understand there really isn't a difference in price between the two for prepaid. Nothing to make a difference when you're taking an international trip anyway.

European 3G bands are different than US ones. In Europe the UMTS band is operating on 2100MHz. AT&T operates it's 3G service on 850 and 1900 MHz.

Yeah but the SGS2 has the 1900MHz band in it, so it would work on AT&T's 3G network, but only on T-Mobile's EDGE.

You need both bands for AT&T 3G. 850 provides downlink. 1900 provides uplink. In Europe, 2110 is downlink and 2150 is uplink. It is normally just included in one spec of 2100MHz. The 850MHz band in this device would only provide 2G speeds.
AT&T is your best bet.
