I had read in a thread by azwildcat98 "We know that AT&T uses the 850/1900/2100 MHz US 3G bands, while T-Mobile uses the 1700/2100 MHz US 3G bands, therefore making each carrier's hardware incompatible with the other's 3G network"
I am looking for possibly a list of non-AT&T distributed phones that work on AT&T's 3G network. My reason is that I currently have a T-mobile HTC HD2 connected to AT&T's EDGE network and i am paying $10/month for "non-smartphone internet" (because AT&T and T-Mobile dont exchange their IMEI # database apparently) AT&T thinks i have a crap flip phone... So i dont have to pay $30/month for "smartphone internet." How can i achieve AT&T's 3G speeds while not purchasing an AT&T branded phone so i can continue paying for "non-smartphone internet'?
My problem could be solved by just buying an AT&T branded phone, but im saving $20/month my way.
The only answers I really want to see in this thread are: What non-AT&T branded Android smartphones are out with 850/1900/2100 MHz US 3G bands?

There are a few carriers that use the same bands. None in the US though. The Closest is Canada. Just a warning, the carriers and OEMs to prevent this sort of thing. While they can't tell what phone your using they are starting to be able to tell if its a smartphone or dumbphone.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
I finally found a non AT&T branded phone that has the 850MHz required AT&T 3G frequency! but i dont want that phone, any others?
http://pocketnow.com/hardware-1/how-to-get-an-htc-hd2-with-3g-on-att
Edit: I think i came to the conclusion that any unlocked phone will achieve AT&T 3G speeds if is has 850MHz, and i can get my "dumbphone internet" if the phone is "unbranded" or branded as a carrier other than AT&T.
HTC Sensation z710a (Unbranded) will work with AT&T 4G speeds! gonna try to get one and hope my $10/ month deal holds up... I figure im saving 12months x $20 = $240/ year without "smartphone internet" so i dont care how much i pay for the phone.
This may be stupid, but I can't find the answer in this forum.
I am drooling over the Titan, but am with T-mobile US and can't switch anytime soon.
If I buy a Titan 3rd party, can I use it for voice and data on T-mobile? Will I get full speed data?
Thanks.
You will get voice and data, but only 2G speeds. That goes for both the international version and att version.
Any info on some kind of quad band version that will work on both AT&T and T-Mobile?

Titan is quad band according the htc.com
HSPA+/WCDMA 850/1900/2100MHz and Quad-band GSM/GPRS/Edge 850/900/1800/1900MHz
Shouldn't this work then? ATT's specs also say 850/1900/2100 MHz for HSPA/UMTS. T-mobile's HSPA/UMTS is on 1700/2100 MHz (according to Wikipedia). For the 2100 band, it should work, right? I am unsure as I am a simpleton and just comparing numbers and assuming that is all that has to match.
I would guess this would require an unlock.
T-Mobile uses both 1700 and 2100 bands for their 3G/HSPA+.
This is why it will not work.
I know because it pains me to not be able to get this device on T-Mobile.

I tried, don't even think about it.
Go with AT&T GoPhone if you have Titan (Simfree), i am enjoying Unlimited All, (Call + Text + Web 4G ) with only $50 a month . Titan can get HSDPA+ (i think) on AT&T.
Im using the titan, unlocked on t-mobile and it does run on edge. honestly its not tooo terrible but edge sucks. and i cant get picture messages. idk i just might keep my hd7, sell this phone and wait for something better on t-mobile that i can actually use hahah but i love the giant screeen
Does this mean the Titan would get 3G or better on T-Mo US now?
http://www.phonearena.com/news/T-Mobiles-consolation-package-3-billion-7-year-3G-roaming-deal-128-AWS-markets_id24956
AT&T and T-Mobile UMTS Roaming Agreement
AT&T and T-Mobile agreed to roam on each other's UMTS bands for the next 7 years following the formal withdraw of AT&T's merger offer. As to when that becomes effective I do not know; I've yet to get an answer from either AT&T or T-Mobile on the subject and that's assuming they'll tell you; it takes an act of God to get through to AT&T's equivalent of T-Mobile's Tier 1,2 and 3 tech support. We have both AT&T and T-Mobile; and in the here and now, neither are compatible on each other's high speed bands; I have the Titan with AT&T and the Rhodium with T-Mobile; my Rhodium unlocked for use on AT&T and despite 3G in Columbus, GA and Auburn-Opelika, AL; I can only use Edge on AT&T. On my Titan it's either "E" or "4G", no 3G. What I have noticed is the Titan favors 4G and seeks those towers which is great if you're in the city, but rural; forget it. It's all Edge out here. It will hit the T-Mobile tower which is 4 bars in our Opelika location but immediately go to either no service or a 1 bar sometimes on 4G and others on Edge. We all know that "4G" isn't 4G and of course "Unlimited" isn't unlimited and politicians and marketing gurus think we're all stupid.
Ok guys I have an atrix 4g running on t-mobile. My question is why cant I get 4g/3g on this phone ? T-mobile runs on the 2100 band and the phone does support that band so why no 4g or 3g? common sense would tell me that if t-mo runs 4g on 2100 and the phone is capable of running on 2100 that it would work. have searched for a total of about 4 hours or so over the past couple days and cant find a straight answer only thing i can find is that att doesnt run on 2100 band yet the phone does. thanks in advance to anybody that can answer and taking the time to read.
are you getting H+ or H? (This is "3.5g") The Atrix 4g is not a true 4g phone.
Because the 2100 spectrum that you're using the phone on now is part of the quad-band gsm which is edge/2g. The difference lies in the bands used for 3g/4g, in which case AT&T only uses 850/1900 and tmobile only uses 1700/2100.
There is also a bunch of things that include HSPA, AWS, WCDMA, and so on and so on but I don't know enough about that to comment.
EDIT: Also, the only phones I know that can be used on both AT&T and Tmobile 3g/4g are "penta-band" phones like some European Nokia phones and the unlocked Galaxy Nexus that needs to be imported as well.

Wcdma=utms=3g
Yes, WCDMA and AWS(1700), as far as I know, are both from UMTS and the differences in regards to 3G between AT&T and Tmobile lie in the spectrum use (850&1900 vs 1700&2100). And both AT&T and Tmobile use HSPA(+) based off their respected UMTS frequencies.
I just don't understand the "leap" in GSM technology that breaks the quad-band compatibility, that's all.

Also I've read 850 is att's main spectrum for large areas and 900 for T-Mobile. All higher spectrums are for smaller, rural areas.
If your looking for 3g maybe find a town or, buy a dual band amplifier? That's IF they have 2100 MHz band working where you are located.
Lower bands ie 850/900 are the download streams. 1700/1900/2100 are upload streams. If I'm not mistaken
Also a T-Mobile vibrant supports att, it also has our main band, 850mhz. Again which is the main large areas, like T-Mobile 900mhz. 1700-2100mhz for att/T-Mobile range is only as good as the towns that still has that band currently operating for hspa/3g data. I've seen alot of T-Mobile phones that have 850/1900/2100, and work on att. If they were 1600/1900/2100 did not for me.
You need that lower frequencies to ensure it to work. Then....
Also for regional based frequencies...
http://en.m.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
That link will let you know what that all really means.
I think you are mixing up gsm and umts.
GSM = 2G/Edge
UMTS (HSPA, HSPA+, HSDPA/HSUPA, WCDMA, AWS) = 3G
Have a look here. You will see they label "3G" as "UMTS" which is HSPA/WCDMA. A little more down you can see they label their data as "HSDPA", which is download, and "HSUPA" which is upload. Further delineating the speeds they label either one as UMTS for down and Edge as up, which to me tells me they use gsm for the upload and only use UMTS for download. Either way, there is not a T-mobile phone available that can be unlocked and used on AT&T's 3G, just 2G and vice versa. As I have previously mentioned, you will need a penta-band phone for that.

And don't get me wrong, I'm not trying to give anyone a hard time but it's misinformation to tell anyone that a T-mobile phone can work on AT&T 3G.
And I'll say it again, I'm not an expert so if anyone can better explain then I'm all ears (eyes).

I am just merely stating that I have a motorola defy on ATT, and it worked great for a long time with great speeds before I got a motorola atrix and infuse.
Im not saying that every tmobile phone will have working talk/text, or data for that matter. I have just posted an idea, or atleast what to look for when you are cruising for phones not labeled for your carrier.
I was getting my motorola defy with the att "grand fathered internet" for 10 dollars a month and it was about 160-420KB/s down, and 80-190KB/s up. but some phones are capable of this, others arent. I have a general idea, and have played with several different carrier cellphones and used them with att and att's 3g data.
Rogers HTC Dream (x2 of them)
Telus Milestone
Tmobile Defy
Rogers Atrix
ATT Atrix (x2 of them)
ATT Infuse
Rogers and Telus actually use the same 3G bands as AT&T so as long as those are unlocked they will work. And I'm not saying an unlocked T-mobile can't work on AT&T, because they can (they both use quad-band gsm) but you can not use an unlocked T-mobile phone an AT&T 3G. That's all I'm saying.
Now, they did make an European version of the Defy that uses the 850 3G band but not the T-mobile "branded" one.
I'm going to stick to my guns on this one because I don't want to give anyone the wrong idea about interchanging AT&T and T-mobile phones and expecting 3G service. I'm fairly certain about this and unless someone can prove otherwise that's how I will think.

Upon further research, I have found this article, where under certain circumstances, you can use an unlocked AT&T iPhone with T-mobile 3G:
http://www.gsmarena.com/tmobile_usa_running_1900mhz_3g_in_some_areas_iphones_invited-news-3537.php
Now, this shows that an AT&T phone can maybe use T-mobile 3G but not the other way around. Again, I'm always up for learning something new but I need references/proof.
Well I do get att 3g on the defy and vibrant. I am currently getting about 300ish KB/s on them and 600+KB/s on my attic, I'm just going with the facts. Those facts are that certain T-Mobile phones will work with Att, provided they have 850mhz band. That allows you in most towns (near me) to get 3g
False.
300KB/s is Edge speed, which is only 2G.
http://en.wikipedia.org/wiki/2G
http://www.phonescoop.com/glossary/term.php?gid=107
That's why you get faster speeds on the Atrix because it actually uses 3G.
Again, both AT&T and T-mobile use quad-band GSM. Which is why you can unlock a T-mobile phone and use it on AT&T, and vice versa, but it is only 2G/Edge and NOT 3G.
http://www.phonescoop.com/glossary/term.php?gid=139
http://www.phonescoop.com/glossary/term.php?gid=3
Furthermore, here are the wiki pages for AT&T and T-mobile which both inlcude frequency charts outlining the technology (2G or 3G) each one uses:
http://en.wikipedia.org/wiki/AT&T_Wireless
http://en.wikipedia.org/wiki/T-Mobile_USA
Here are the charts:
AT&T:
Frequency Protocol Class
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
T-mobile:
Frequency Band Protocol
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G (formerly 3G[34])
1900 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G
I check for facts and references, I'm only saying what I find in research.
Again, when unlocked, a T-mobile phone can use AT&T 2G/Edge, not 3G

I just purchased an AT&T branded Titan for use on T Mobile here in the USA. I didn't do my research properly and I just assumed I would get at least 3G. It seems not. However all is not lost if I can just unlock it and use it on my trips back to Scotland.
If I unlock the AT&T Titan will I have any issues just popping a UK SIM in there? Does it run better on some providers?
Thanks

You will need to check with the Carrier that you are going to use the Titan over there... and see which bands of HSDPA that they support. The UK Version of Titan seem to be supported 850/900/1900/2100 , but i don't think the AT&T version support 900 band tho. You will have to recheck.
Good Luck.
And yes, you need to get the SIM-Unlock code based on the IMEI of the phone and then you can insert any sim in and the phone will use it just fine as long as the carrier able to provide network for it.
Looks like you will only be able to use it on GPRS
UMTS/HSPA/HSPA+ tri-band (2100/1900/850 MHz) and quad band GSM/GPRS/EDGE (850/900/1800/1900 MHz) and LTE BC4/BC17
Thanks for the replies. It makes no difference to me what network I use .
I'm having a hard time understanding the differences.
If I look at this page it lists what my phone supports..
http://www.gsmarena.com/htc_titan-4027.php
Looking at this it seems my specs match up with most major UK providers
http://en.wikipedia.org/wiki/List_of_mobile_network_operators_of_Europe#United_Kingdom
Therefore shouldn't it work?
If it is limited to GPRS what are the limitations?
Thanks
Yep in theory it should, Just double checked and I posted specs for Titan2 oops
At&t Titan ie: Frequencies HSPA+/WCDMA 850/1900/2100 MHz and Quad-band GSM/GPRS/Edge 850/900/1900 MHz, Its missing 1800mhz for UK which basically means you cannot use T-mobile or Orange, But Vodafone or O2 or anything running 900mhz should be fine.
The 2G band list says "quad-band" but then only lists 3 bands. I'll bet that's a typo and that all 4 bands are supported.
I've used my unlocked AT&T Titan with local SIMs in numerous countries on 2100MHz 3G... works great.
I have at&t Titan from US in London with O2. Sometimes it woks fine on 3G sometimes doesn't work at all. I forced it to use only 2G and then it works fine.To force the phone Enter code ##3282# Then go to the Three blue dots on the right corner go to settings and in network type choose 2G or 3G depending on what you want.
Received my Titan 2 today from Across the pond, It's at&t branded but unlocked, It is working fine and shows 4G lol, I know it is just a 3G connection but no problems using it on O2, Had to manually input APN settings in cellular and that was it
Well that smile didn't last long, Can't send pic messages, Any ideas?
Hi AndyFZ1S have you tried the connection setup application from htc? Thats what i usedwhen i moved here and it worked fine. Still my 3g connection is poor or inexistant is most areas, i believe at&t phones are missing one band.
Sent from my Titan using XDA Windows Phone 7 App
^@andres22, Thanks & yes have tried connection set-up but it says the carrier is not in the database etc, 3G works fine I just cannot send or receive picture messages, There is no option to manually put in the settings either so am kind of stuck really,
Uhmmm funny that my setup apolication has O2 settings and yours not. Sorry man. I cant think of anything else.
Sent from my Titan using XDA Windows Phone 7 App
No problem, It may well be you have a different database on your at&t Titan compared to the at&t Titan2, Never mind, Hopefully there will be a way to sort it.
I'm having similar issue with Titan 2 using on T-Mobile US. MMS is the only issue. T-Mobile does carry Nokia 710 and HTC Radar. I wonder if there is a way to get settings from those phones.
Sent from my HP Touchpad using xda premium
The only way I can think of doing it is by flashing either a Stock Titan2 ROM (if it exists) or a custom one, That way Connection set-up would have most of the carriers in its database and not just at&t, But that won't be possible without HSPL or any ROMs, Maybe HTC could do something their end to update connection set-up etc?
I know the Jetstream was designed to be run on AT&T and Rogers, but I am curious if it is possible to flash a radio to enable usage of T-Mobile's HSPA network, much like the Samsung Galaxy Note has been enabled to, as seen here.
Can any of the amazing Devs out there shed some light on this?

jdavis08, Simple answer is yes. It is a standard 2G / 3G / LTE (AT&T / AWS band) phone. So you can use it on ANY 2G / 3G / LTE network with a SIM. But you may need to break the SIM Lock on any handset.
Just wanted to clarify. The Jetstream is 2G/3G/LTE /capable, 2G (GSM): 850/900/1800/1900MHz, 3G (UMTS/HSPA): 850/1900/2100, and LTE: 700mhz & AWS-1700/2100.
Currently, T-Mobile only uses the AWS for their HSPA+ network, not LTE (from what I understand, AWS will be transitioned for LTE and 1900mhz refarmed for 3G/4G early 2013) - and if I'm not mistaken, the HSPA+ is only supported by the "3G" band of this device, not the "LTE"
So - to make a long story short. I am a T-Mobile subscriber with various "4G" phones from T-Mobile. Their 4G only works if the phone has a radio with AWS for HSPA as T-Mobile (unlike AT&T) does not use the 1900mhz for their HSPA (yet). I own this tablet.. It has been SIM unlocked and it simply does not get anything above EDGE... and I live near and visit major cities in Washington State, Seattle/Bellevue/Tacoma, which definitely have TMo's 4G coverage.
I know I should just cool my jets until TMo rolls out the network upgrades, as I have no interest in joining AT&T. I was just curious if there was some way to "trick" the phone to use the AWS frequencies for HSPA, like the Galaxy Note has been made to do as the radio specs are identical.
I know that the Note was enabled to do this by flashing another radio. Support is minimal for the Jetstream these days... so I was just reaching out.
Thanks guys
