Hi, I'm in California and I have an Motorola Atrix with AT&T and I just unlocked my phone because I'm about to switch to T-mobile...
However, my friend told me that AT&T and T-Mobile has different 4G networks. He said the AT&T Atrix can not use 3G or 4G speed on a T-Mobile network, It can only go up to Edge speed.... Is that true? Does anyone know about this?
Hope some people can help me here ...
Thank you

From everything I have read that is correct, but also know that it won't be much longer till you are back as an AT&T customer since they are acquiring T-Mobile.

Its true. While both AT&T and T-Mobile use HSPA+ for their "4G" speeds, they run on different bands. If you want 3G/4G, use a T-Mobile phone. Otherwise, enjoy EDGE. Opera Mini with images set to low will be a big help.
T-Mobile leases cellular space from AT&T which is why unlocked AT&T phones can use T-Mobile service. Not sure if it is the phone's software issue that is causing the 4G/3Gnot working. It's possible that T-mobile implemented their so called 4G first but it's still AT&T equipment.....I work for AT&T. Also 4G, is just higher speed 3G, 4G LTE won't be rolling out until next year.
Thank you for the quick reply... I need to get a T-Mobile phone then.

Yep, but sucks that they still charge minutes when I call a T-Mobile number. I'm switching it for my girlfriend, so I can get Unlimited mobile to mobile minutes... I might get a sensation when I switch to T-Mobile

Good job on the misinformation front.
And also not being helpful, I'm going to assume your in sales and don't actually know anything.
Now on to the OP's question.
T-Mobile uses the same type of technology as AT&T however they operate on different bands. As such most devices that are sold on AT&T will be able work on T-Mobile for phone and edge but don't get 3g or hspa+ due to the radio in the device only supporting some of the bands. Which is why as a general rule AT&T phones such as the iphone, will work on T-Mobile if unlocked but can't use 3g because it doesn't have the ability to operate in the correct MHZ range. Its the same going from T-Mobile to AT&T. My HD2 was awesome, other then the slow data. *Not that my atrix or inspire are much better.
There are exceptions to the rule though. You'll have to check to see which bands the Atrix is capable of using. I know some of the Samsung devices had all the GSM bands so they worked fine on all networks.
the answer is NO the atrix will not work on tmobile USA 3G or 4G network. there, done!

Problem is that if/when the AT&T/T-mobile merger goes through, AT&T will likely flip Tmobile's 3g towers to 4g. All tmobile 3G phones...sorry no more 3g unless you buy a new phone. yay....
linky
AT&T said Monday that it planned to convert T-Mobile's 3G towers to 4G service and move T-Mobile 3G subscribers to AT&T 3G phones.

They won't just flip a switch and everyone has to buy new phones. They will be phased out as people finish contracts and begin new ones. If they don't, they'll be buying T-Mobile customers all new phones or paying fatcat lawyers to defend them from all the lawsuits.

Agreed, sorry I used the term 'flip', never meant to say it would happen instantly . The article I linked stated the switch would take several years. That's not written in stone though, AT&T could move up the timeline if they are losing too many customers to Verizon and Sprint.
This is only an issue if you plan on keeping your tmobile 3g phone for YEARS, which is not likely for anyone that frequents xda .
I recently purchased an unlock galaxy s2 i9100. It is supposed to be GSM unlock with HSPA+ 21Mbps/HSUPA 5.76Mbps, EDGE/GPRS Class 12, Quad band GSM 850/900/1800/1900, Quad band UMTS 850/900/1900/2100 hardware capabilities. since I have gotten the phone i have not been able to connect to anything but edge. Tmobile assured me i had the correct APN setting. I would like to know if anyone know what I could to to enable the HSPA+ T mobile US uses UMTS 2100 to connect. I rooted and flashed the lite'ning rom.

Nope you won't get hspa speeds on Tmobile with the current international version. You have to wait for the Tmobile variant. International version gets
3g speeds only on att.

This is correct. However, it's only used for one way traffic (either uploading or downloading, i'm not sure which). UMTS 1700 is used for the other direction of traffic on T-Mobile. This means no 3G/4G without both frequencies.
Your 2 options:
1. Get a T-Mobile phone.
2. Switch to AT&T.

thanks for the quick and concise responses. I have a clarification: does this mean that I when Tmobile comes out with the variant my phone will be able to upgrade to Hspa via a rom or radio update or that if i want to keep this model i will have to wait to swap it out for the tmobile version

The I9100 will NEVER work on T-Mobile. The SGS2 that they are releasing has different HARDWARE. There will never be a way to make the phone you have now work on T-Mobile 3G.
As others have said you'll need a different phone in order to get it to work on T-Mobile USA's 3G/4G frequencies.
You'd need a penta-band phone in order for it to work on all of them. I think Intel is curently working on that or already did but that's all there is. You'd need both 1700/2100mhz in order to use it with 3G.
I don't get how people don't research before they buy!!

Excuse the noobish question, but to make sure I have this right - You need both 1700 and 2100 bands for the 3g or 4g to work at all, correct? Was looking into buying it once its released but that may be a deal breaker if no speedy internet.

Yes, you need both, or you will be stuck using EDGE if you are on T-Mobile US.
I want to know the same, if the intentional version will surely work on Tmobile.
Sent from my GT-P7510 using xda premium
I'd like to know about that as well
I think everyone here just wants to know when the hell it'll be coming out to our own carriers. I need a new phone but I'm not waiting until Fall for one.
Doesn't t-mobile uses the 1700/2100 for 3G and 2100 for 4G? so it would be EDGE and 4G.
So your implying that 4g will in fact work? I thought you needed both bands for 4g to work.
I'm in the Philadelphia area and really need to know if this will work or not.
If I can get 4g, ill be preordering the phone asap. If not.... I'm still undecided.
nope, im asking if thats the case. i need to ask the dude that know, since he is the manager at the t-mo store if thats rite. but t-mo one should be coming out in month or two.
What T-Mobile calls 4G is really their 3G HPSA network. They have not yet rolled out LTE. So for you to get the T-Mo 3G, you need the phone to support 1700/2100 band, which I am not sure the international SIII model does, but I'm almost certain it does not. Therefore, you will only get 2G (EDGE) speed, which is around 10-15kilobytes per second download, good enough for web browsing and loading Google Maps, it's about 3 times faster than 56k modem.
The T-Mobile-locked model will support the HPSA+ 42Mbps speed and AT&T version will have LTE of course. Now whether if when this phone get released for T-Mobile and somehow it will preemptively support their future LTE service (launch in 2013), then that would be interesting (which inherently the hardware does support LTE due to the Qualcomm S4 chip to be used in American models). What I predict they will do is like with the Galaxy Vibrant -> Galaxy S 4G, so first release the HSPA+ only version, then release a slightly modified version that support LTE.

If this doesn't confirm lack of 1700, nothing does.
So basically, count on the international version not being usable (besides EDGE) on T-mobile. You'll have to wait for them to up with their own version.

Dammit why does T-mobile use such obscure frequencies!
I want the 64gb version, will AT&T's HTC One work on T-Mobile's HSPA+ Network??? I get sick speeds on T-Mobile's HSPA+ Network, over 20mb down and 5mb up. After 6 oclock it gets faster. These are not just spiked speeds these are every day speeds all day. I hoping to hell that HTC somehow put T-Mobile's HSPA+ Network in AT&T's as well. Has anyone tried this yet.
Thanks, Vinny
I was told it won't but don't quote me on it I'm not 100 percent sure.

Please post your results, only issue the phone might have to be unlocked to work on the others Network, I think. Would love to get my hands on the 64gb version, pissed off T-Mobile just doesn't have it. May have to bite the bullet and buy the 32gb version but still hoping that AT&T's 64gb version is a go on T-Mobile's HSPA+ Network, I know the LTE will work OK it is just the HSPA+ Network that is in question.
Thanks
I just talked to the HTC tech support dept. today and they mentioned that although on their site, all the speeds are listed for the 64Gb developer edition, the phone will only work on 2G on T-Mobile's network! Yes, that was 2G, not 3G, not UMTS and of course not LTE. I just signed up with AT&T and I get nothing but dropped calls, disconnects, garbled voices, data drops or no data. That happens every day, quite a few times, at different hours of the day. I had wonderful luck with T-Mobile here in Orange County, CA before. I'm selling my HOX+ for an HTC One, but I'll stay with AT&T because of the penalty and the 2-year contract. It's not Europe here... Oh, well.

I can confirm. Att version will not work on Tmo HSPA+. It works on some bands (in some places), but not good enough to think about trying move one phone to the other carrier either way. The Tmo version works a little better on the Att network, but again doesn't support all the correct frequencies. I'm returning the Tmobile version and sticking with the Att one for the better network here in Austin.

So, after selling the HOX+, I got 6 HTC One's thinking it might have been the phone. All 6 of them had the same network issues. So, it's AT&T in my area that has all those problems. I have confirmed with 2 of my friends and my wife and we all have similar problems. Does AT&T work in more than 5 US cities? Wow - nothing but problems. In any event, the HTC One's had crack problems and the On/Off button was very recessed and half of it was inoperable so I returned all of them!!!
I only have problems with att during and immediately after wicked storms.

I have the unlocked version sitting on my desk right now.
The only difference seems to be that the radios are not the same?
But I've been reading that the radio might be flashable so it can accept Tmobile frequencies.
One question though, can ROMs from the unlocked version be used on the Tmobile version? Thanks

From what I have read, the T-Mobile H1 can flash any ROM.
The radio flashing is an open question. So far attempts to get the AWS working on the dev / unlocked models have not worked. HTC says they have different radio hardware, but at this point it is anyone's guess if we will ever get AWS working on dev.
If you use the unlocked / dev on TMO, you will get 21 Mb on the 1900 refarmed band, and eventually LTE if you live in an area that has it. Right now there are maybe three areas with LTE.
If you got the 32 Gb unlocked, in my opinion it has no advantage over the T-Mobile model. The Dev edition has 64 gb of storage.

The tmobile version flashed to the unlocked ROM should retain AWS on HSPA+, correct? That's the route I will probably be taking. The additional LTE bands are inconsequential for me - mainly south america and Philippines.

I don't think anyone has tried that yet. I suspect AWS wouldn't work without some modification because the ROM would not support AWS. But I don't think it would hurt anything either.

Yes, flashing ROMs doesn't affect frequency compatibility. All GSM One variants have the same hardware and ROMs/kernels are cross-compatible (international HSPA-only, and EMEA/AT&T/T-moblie LTE). ROMs don't include radio software, and so far at least, radio software hasn't affected available frequency bands.

If flashing ROMs (not radios) to/from intl, US, EMEA models don't affect supported bands, I don't see why it would affect tmobile -> unlocked. Advantages would be no tmobile bloat, no hacks to please the tmobile overloads, etc.

It sounds like you're disagreeing with me or something, but yes, flashing an international ROM on tmo One is great because it gets rid of bloat, can edit APNs to enable tethering, and always based on latest firmware rather than waiting for tmo to push an update. Only downside I know of is no wifi calling. I'm running TrickDroid on mine and it works great.

Sorry, that was more directed at stevedebi's comment. Wifi calling can be replaced with SIP calling so that should be fine.
Warranty problems?
One potential issue with getting the T-Mobile version could have to do with the warranty. U.S. carriers seem squeamish about people modding their phones and threaten to void the warranty for unlocking bootloaders, rooting, etc. That said, I don't have specific info at hand that HTC unlocked phones are much more lenient but seems worth looking into.

Well, most of the new T-Mobile plans come with unlimited hotspot and WiFi calling. I'm not planning to unlock mine. My One is performing fine on the stock ROM, and TMO will update the software (eventually).
As noted above, I'm not sure that T-Mobile looks kindly on having TAMPERED show up on a phone. They might well deny a warranty claim.

Switching from H to 3G is just what the radio does; it's how the interface is supposed to work. The T-Mobile version works exactly the same way--and you can see this if you flash an international ROM on your tmo One--but tmo assumes Americans are idiots who a. don't know what HSPA+ is, and b. get confused if the radio idles at "3G" when they expect to have "4G" coverage. So stock tmo ROM just shows 4G all the time, but it is just themed connection icons really. Seems like they're right to do this, which is a bit sad.
Of course, that doesn't mean that you would be getting the same speeds with the dev edition, since even in refarmed areas, you could well get better UMTS coverage over AWS than PCS.

Not to mention that in many cases you get EDGE on 1900 even in refarmed markets.
yeah I was thinking of getting the DE because its 64gb but then I realize that with wifi everywhere, I can just upload pictures or videos to you box account, then delete them to make room, and keep installing apps I want and delete those you dont.
After dealing with 16gb in a Gnexus, you learn how to manage to space

You are right if you go to phone settings-about- network you could see UMTS and HSPS+ it swicthes between UMTS 3g and 4g HSPS+ and my 4g icon stays the same, this also happen to my old HTC one 64gb developer edition but it never showed the 4g icon like T-Mobile HTC one all it showed was 3g and H icons this happens in a 1900mhz refarm area. Look at T-Mobile HTC One as example thank god it has 1700mhz built-in that's why I got ridoff my developer Edition

The tmobile version flashed to the unlocked ROM should retain AWS on HSPA+, correct? That's the route I will probably be taking. The additional LTE bands are inconsequential for me - mainly south america and Philippines.
