US T-Mobile HD2 on AT&T? Yes or no?

I'm pretty sure the answer to this is implied or even obvious to some of you out there from the technical specs scattered around this website (and others) on the different flavors of HD2, but I'm unable to reach a conclusive conclusion on my own, so I'll simply plead ignorance and ask it outright:
If I buy a US T-Mobile and attempt to use it on the AT&T network with my 3G AT&T SIM card, which of the following will happen, to the best of your knowledge?:
It won't work at all.
It will work, but only for EDGE access.
It will work as a 3G phone just fine.

It will work on At&t, but GSM only, meaning only voice and edge. You will not be able to get 3G, no matter what rom or radio you flash.

Yep, the above is correct. It will work on Edge only. However, do note that the phone would have to be unlocked first. If you just switch the SIM cards it will not work

currently, it won't work at all.
No one has reported to unlock this beast successfully.

Thanks for the feedback. I'll stay away from this experiment then.

ive got mines unlock and im loving it despite the t-mo brand at the top other then that im loving it.im only egde but it really doesnt matter.

buy the telstra hd2, it will work on att 3G

I successfully unlocked my T-Mobile HD2 yesterday (to switch back to AT&T) after visiting the following site: htccode.com
It'll cost about 25 Euros to get unlocked... Also, the support person is pretty responsive.

In looking at the band frequencies for the HD2, it appears that you may be able to set it up for AT&T's flavor of 3G. Is this correct?

Yeah, the GSM(1900+850) in the band frequencies threw me off. I thought that was what AT&T used for 3G. Doesn't matter to me, I'm on T-Mobile anyway... and I keep my 3G off most of the time for battery conservation, lol.

HSPA?

Ok who's got the trick to make the phone report what radio frequencies it can do? I have a bunch of Android codes that make phones do certain things, but none of them work on the streak.
I am trying to find out what my device is capable of since there are too many threads out there that say it can and it can't... i.e. hspa....
anyone? Beuhler? Beuhler?

No idea on the codes mate, sorry.
But if you were asking if it does Hsdpa.. I can confirm it does.
Apologies if I misread ur question tho

have you a look in your system/build.prop
also do you have EMlist enabled? Engineering Mode?
try this one *#4636#*#* (*#INFO#*#*)
definetly does HSPA , mine is set at the highest settings as far as I know,
best I've seen so far was wabout 2.5Mbps download on ATT
havent checked wi-fi yet.

Ok that code worked, and in phone info section, I am currently set to GSM auto (PRL). You're on ATT... the question is about whether or not the device will do HSPA on Tmobile's network. Currently I only get EDGE.
FYI the correct code turned out to be *#*#4636#*#*

Hey Lord60,
Are you in US? If Yes, I would be also interested in getting Streak to work on TMo-US's HSPA network (offcourse if hardware supports it). I think (not 100% sure) EMlist has a option to see all UMTS supported by phone. May be way to even select/set them.
If you find any info, please share it and I will do the same.
I've been asking Dell, if their new unlocked version will work on TMo-US's 3G network. And no one seems to know it.
I already have Streak but like in your case, only works on EDGE.
Thanks!

Im pretty sure it supports the Tmobile 3G band,
I think there may be a thread somewhere, I will check later and report anything I find.

first comment says it works for him... I know it could be fake.
but Streak is QuadBand,
you may need EMList and manually input select the band.
Im 99% sure you can do Tmobile 3G

and from what else I find...
looks like the beta Tmobile versions supported 3G, and now only UK versions will support tmo 3G, and Dell "says" ATT locked versions dont have support for Tmo 3G.... I would say try an unlock code first, the radios should al be the same.. if you get tmo 2g, Im pretty sure they left the tmo 3g radio in there as well.

The Streak is quad band gsm. That's 2G speeds. TMo 3G speeds work on AWS 1700 band. There were only a handful of beta phones with those specs. If you're looking to flash a whole new Rom including the radio frequencies then I guess it's possible. There are some really talented people here. Dell already has FCC clearance for the AWS version but hasn't released it to the public yet, if ever.

Hey chrisrotolo, I bought Streak back in September w/o AT&T contract and got it unlocked by calling AT&T.
When I put my TMo sim card, it only works on EDGE/2G. It never worked on 3G.
I've seen a screen shot of EMList which shows you and may be lets you select UMTS bands, but in Mr. Steve's 1.5.1, EMList is not included i believe.
When Dell recently announced Unlocked Streak (back in November), there were rumors that it might work on TMo-US 3G network. So far no one seems to know for sure.
So guess we are out of luck, as of yet!
Thank you for the reply though!

Hey Streakr, I always thought that radio frequencies has to do with the hardware and not with ROM.
Now that you mentioned its controlled on the ROM side, I wonder how easy/difficult it is to support this on Mr. Steve's ROM.
May be Mr. Steve could answer it for us.
Thanks for the info though.

Yeah I am unable to get EMList on dJ_steve's 1.5.1, you could ask him to bake it in Im sure, but I can get some cell info stuff when selecting >shortcut>bettercut>all applications....
I would love to find a list of AT&T's (or T-Mobile's in your case) full list of USSD codes or MMI Codes ( eg.*1234# dialer codes), for network, service and diagnostic stuff. I am sure it would be very easy to screw something up with those codes as well.
maybe even some fastboot codes...
I found this link on gsmhosting, anyone know any more of these codes, you can enter from keypad on fastboot screen?
http://forum.gsmhosting.com/vbb/f606/dell-streak-secret-codes-p-1113827/
I dont know if you can access any of the mobile networs through settings and manually configure it through APN or manual network operator.
cheers!

From what I have been told the radio frequencies are set by the manufacturers. The hardware is capable of doing any of the operators frequencies but how each is set I'm not sure of. I have heard of people who have claimed to have changed a EU version phone to a US version phone including the carrier settings. This is way behold me.

any new updates on this?

[Q] Buying an Atrix 4G, difference?

Hi all,
Im thinking of buying this phone but from what i have read there isnt much difference between the Atrix and the Atrix 4g.
How will I be able to tell which is which? specs are almost the same.
Should add that I am buying used. Also, I am in the UK.
Look forward to your replies!

They are the same phone!
I'm also in the UK, really like my atrix, but coming from a modded android to a locked phone is a bit difficult...

your sure? i read somewhere that the first atrix has 5mp cam which has been upped to 8mp in the new version.
Maybe im mistaken.
Yes ive heard about Moto not playing nice with rooting!

It is the Atrix 4g and the Atrix 2. And the Atrix 4g has a 5 MP camera and the Atrix 2 has a 8 MP camera. The most noticeable thing I saw in the looks of the 2 phones was the Atrix 4g has the speaker on the back at the bottom and the Atrix 2 has the speaker on the front at the top.

yeah that's right... looking at the specs on motorola website, seems that's the only difference!

cool, now i know what to look out for!!!

atrix(4g) is not a locked phone, is it? If you follow the guide, you can unlock the bootloader and flash different ROMs on it.
Another difference between atrix(4g) and atrix 2 is the fingerprint scanner. atrix 2 doesn't have it.

Since you are in the UK you will probably want the "Motorola Atrix" since it has the 900MHz UMTS band needed for some UK carriers like Vodafone and O2.
The "Motorola Atrix 4G" is the title used for the Atrix line that is used in North America for carriers like AT&T and Bell.
Look at these two links and you will see that the main difference is the bands used for their 3G networks. AT&T and Bell use 850/1900 and Vodafone and O2 use 900/2100.
http://www.gsmarena.com/motorola_atrix-3709.php
http://www.gsmarena.com/motorola_atrix_4g-3708.php
I could be wrong but this is what I can gather from your question. Also, you might be able to use the "4G" branded one because it still uses the 2100MHz band (if unlocked) but you might experience reduced coverage (slower speeds).
The difference in cameras is between the Atrix(4G) and Atrix 2.
http://www.gsmarena.com/motorola_atrix_2-4199.php
Which also does not use the 900MHz band.
EDIT: I would also like to point out that they do all use the same "Quad-band GSM" but that is for the 2G(EDGE) network, and not 3G(UMTS/HSPA)

Some suggested the only difference between atrix and atrix 4g is the firmware. But I don't know how true it is.
I have a Bell (canadian) atrix 4G, and I am currently in UK on O2. Is there any way to tell if I can use UMTS900 or not?
If there is a way to tell, and I manage to connect to UMTS900, then I will say there is no difference between atrix and atrix4G.

Right, an unlocked Bell/AT&T Atrix will work on almost all of the UK networks but it will be restricted to the 2100MHz band for 3G(HSPA) or quad-band GSM for 2G(EDGE).
You don't need to try "to tell" if your Bell Atrix is using the 900MHz band for 3G(UMTS/HSPA) because it cannot. It's in the specs, it just doesn't have the capability.
http://www.bell.ca/Mobility/Products/Motorola_Atrix_4G/Specifications.tab
Just to clarify, I'm not saying you can't use an unlocked AT&T/Bell Atrix in the UK, all I'm saying is it will not be able to use the 900MHz band for 3G. It will, however, be able to use it on EDGE/2G. I'm fairly certain it's a hardware thing.

People seems to be either pretty certain it is only a firmware difference, or pretty certain it is a hardware difference. But no one can confirm which one is correct...
I do agree, based on the spec from motorola, US/CA atrix doesn't support UMTS900.

Same result I've had. I've posted a question thread on the modems here.
http://forum.xda-developers.com/showthread.php?t=1442350
Its annoying me because if its just a software limitation, what is there to stop us from giving it 900mhz umts support? The "workaround" just needs discovering by a developer (I've been mooching around, but i'm not dev!)
O2 UK has UMTS on 900MHz now, and one local to me so I want to use it without replacing it for a UK atrix lol.
What we need is an international/uk user to be brave and strip their phone down and find out for us!
My gut feeling is its something in the kernel/drivers/boot loader provided for the AT&T Atrix. On samsungs there is a secret menu for turning bands on and off.. but none of those codes will work on the Atrix of course (even the generic test ones built into android don't work!)

If you know anywhere close to London where o2 has UMTS900 coverage, but no UMTS2100 coverage, then I will try it out.
If I can get 3G at that location, then my Bell Atrix with UK baseband works with UMTS900. If not, then it is more than likely to be hardware.

If you can come down to Solent Business Park/Whiteley you'll have it there on 900mhz. They were digging up the road a few weeks ago right by the mast (which is pretty much line of sight with my office), and I took my Nokia N900 (on GiffGaff as its a spare!) which supports UMTS 900 and it had full 3G signal (atrix had full 2g), which it could never get before. The nearest 2100mhz mast is like 2 miles away. The atrix will pick the 2100 mast up rarely down there, and when it does, it has 1 bar if that.
I tried a few different base bands while at work, none seem to provide positive results on my AT&T Atrix.

When it comes to the differences of the Atrix and the Atrix 4G, it is the 900MHz UMTS band. The Intl version has it but the AT&T/Bell version does not.
While the OP (@jman316) was looking for the differences between these two versions, you seem to be trying to figure out how to access that band on the AT&T version, which is not possible.
GSM and UMTS are not compatible. UMTS is an evolution of GSM but they are not the same. So, going back to your dilemma, you have stated in your other thread that you currently have an AT&T version. Based on that, you cannot use the 900MHz band on 3G/UMTS/HSPA. Only 2G/GSM/EDGE.

To reiterate, quad-band GSM is not the same thing as UMTS/HSPA The AT&T Atrix can only use the 900MHz band on EDGE/2G, not 3G/UMTS/HSPA.
I apologize if I seem derisive on the matter, I just feel that the facts are right there.

I'm very aware of the differences in the technology. I don't know where your comparison of GSM/UMTS and the links relevant here. Its a quad band gsm and quad band UTMS/WCDMA/3G phone with one band disabled be it through a hardware modification to the chip or by software.
What we are trying to drill down to is this:
1. Is it the same cellular modem chip used in both AT&T/Bell and the international versions?
If yes then,
2. Why is it not possible to enable the disabled band?
Has anyone really done any research into either of these? No. If had a spare pool of money I'd buy a UK phone, and strip it down, and prove once and for all what difference there is, and we could then say, oh so the chips are different models so that explains that or go, oh its the same chip/part number, lets hack the software a bit.

Also Atrix 2 uses normal tft lcd instead of pentile as in original atrix.

We are not on about the Atrix 2, we are on about Atrix 4G (US) vs Atrix (UK/EU/World)

I have done a lot of research into the matter and from what I have gathered the chips/modules responsible for the compatible frequencies can be tailored to specs according to the customer's (AT&T) requests. Which, from my understanding, would be a hardware issue. So, even if they have the same chip, it wouldn't matter, since AT&T can have it custom made to just use the frequencies they approve. Which actually sounds a lot like something AT&T would do, given their track record.
I also found this thread where others are pretty certain it is not possible:

What LTE bands does Sprint HTC 10 have?

I can't find any definitive answers on this. All I know is the minimum is 25, 26 and 41 but it'd be nice to know the full list. I travel internationally and without other LTE bands like band 7, it makes it tough to use it anywhere outside the US.
EDIT: Someone answered this question in another thread but it would be good to get screenshots to verify this.

LTE Bands: 2 / 4 / 5 / 7 / 12 / 13 / 25 / 26 / 41
I've heard that the FCC filings show that the Sprint variant is not capable (tested or approved) for GSM or WCDMA, which is kind of disappointing since I travel a lot in Canada. Any confirmation on this?

This list of bands is a little better than both the Sprint variants of the LG G5 and Samsung Galaxy S7. If this phone can be unlocked, you at least have a way to go abroad and use LTE connections in much of Europe and elsewhere. Band 7 is the most common band in the world from what I understand.
I'm curious about this comment about GSM and WCDMA. Hopefully someone can verify this one way or another.

If you plan to travel outside the US during most of this time, your best options are to sell your HTC 10 and get one of the few unlocked flagship phones on Sprint's networks, assuming you want to stay with Sprint.
Here are your options:
Google Pixel
Samsung Galaxy S7 SM-930U
Samsung Galaxy S7 SM-935U
Nexus 6P or 5X
Motorola X Pure Edition
Apple iPhone
Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Thanks for the response. The thing is I'm not on Sprint and have no desire to be. I won't be in the states long. I bought the phone thinking that like most, it could be unlocked and used as needed wherever I travel to. I knew it wasn't unlocked but figured I could do it myself. Well, I've tried a number of times, and keep having an issue with the radio. Can you explain what you mean by bands being crippled? What I'm trying to find out now is whether it's possible for me to get this HTC10 completely unlocked. I think I've done everything right but maybe not. I'm kinda desperate at this point. I love this phone. And if I have to I'll return it and grab another that can be unlocked but I just have a hard time believing that the phone can't be unlocked. It's a strange concept for me. Any help or info would be appreciated.

First, go go Google and look up what LTE bands are.
Crippled LTE bands = the hardware inside the phone will not allow certain LTE bands to work unless physically altered. It doesn't matter which ROM you install, you will not unlock all the LTE bands without physical alteration. https://www.quora.com/Does-installing-different-rom-change-LTE-band-frequency
So no, HTC 10 will never be completely unlocked. Look at the list above and buy one of those phones if you want a completely unlocked phone.

I'm not sure I fully understand. Yes, I know that different chips have different bands that they work with. So, what you're saying is the Sprint HTC10 variant uses either a different chip or has some sort of other hardware configuration that is incompatible with GSM and the wider LTE bands and that no matter what I do with this phone I'll never have a truly unlocked phone? That's what I have understood, so my best option is to send it back. Ok, I get that. But I have read across tons of forums and threads of people who unlocked their Sprint 10s and are able to use them on other non-cdma carriers. So, how does that work? Are all the Sprint 10s the same or are some more limited than others? Are you essentially saying that i would have to get an unlocked/dev edition of the htc10 to be able to use GSM in other countries?
Sorry if i'm asking stupid questions here, I'm just trying to fully understand this. Thanks again for helping me out on this.

If anyone reading this knows better, please feel free to correct me.
This is my understanding of LTE bands and CDMA/GSM radios.
Phones like HTC 10, which are locked, include hardware that are built for specific usages. Prior to HTC 10, HTC phones built for Sprint's CDMA radio were specifically built to lock out GSM radio signals and most other LTE bands using the hardware. This means you'd have to open the physical device and modify the wiring inside the phone in order to allow other signals to work.
As of HTC 10, the locks are supposedly now just software based but I haven't seen proof of that. What this essentially means is that you should be able to unlock the bootloader and flash new Roms that could allow the GSM radio to work universally. However, lots of people are having issues with it. Here's one story of someone who was mostly successful but still had issues:
https://forum.xda-developers.com/showpost.php?p=68960210&postcount=47
Read through the thread above and you'll see a lot of people having issues trying to fully unlock the radios and LTE bands for this phone.
If you ultimately don't want to be on Sprint anyway, I think you really should consider getting something already unlocked that can universally work anywhere. And lots of interesting non-Sprint compatible phones like OnePlus 3t (among the others on the lists I provided) are already unlocked and have a lot of good capabilities and would work great anywhere. The Pixel is one of the best devices out there and the camera is amazing from what most people say.
So I think your options are limited and I'd highly suggest you consider getting a Pixel or something else already unlocked.

They are software based. I have unlocked AT&T bands on my Sprint variant, 2 actually , and they worked perfectly fine. I would show you proof but I am back on T-Mobile which the Sprint HTC 10 already has LTE support for by default.

See my other reply.

ZE552KL not connecting to LTE band 17.

Various websites confirm its compatible with LTE band 17. My other phone connects to it while in my house, but the Zenfone will mostly connect to HSPA+, or sometimes LTE band 2. I cannot get it to stay connected to LTE unless I get into town or on the highway. (Actually as I'm typing, it switched to LTE band 2, but in awhile it will go back to HSPA)
If I root is there any way to unlock band 17? I'm in the US and my carrier runs off AT&T towers. I got this phone specifically because band 17 reaches far off places much better but I am unable to use it.
Edit: I just realized the model number in the Android settings is "asus_Z012DA" and that apparently is not a US variant. I didn't know about the different variants at all. Am I out of luck?

Hi!
Your correct model for band 17 should be Z012DC, the same used in Brazil.

For the time being yes you are. There is a way to unlock LTE bands on Qualcomm devices, but it seems ASUS has a fail safe built into kernel preventing it at the moment. If there is ever a custom rom developed for your phone then it maybe possible to unlock band 17. Until then no. I have been trying on my Zenfone 3 Ultra. Got as far as entering in the values for the bands I want and when I reboot it resets them to default. You can read up on it here:
https://forum.xda-developers.com/zenfone-3/help/help-putting-phone-usb-diag-mode-t3571627
Me and another user have been working on it. Maybe it might work for your phone. Always a chance.

Yeah I realize that now. Even though I'm stuck with my phone, I still can't find the z012dc for sale anywhere. Practically no seller online lists which variant it is. In fact, after a few hours of research, I never even knew there was specifically variants.

Whoa thanks man. I'll keep checking back and maybe I'll try it myself. Seems you guys are close.
I must say though, this isn't a complete deal breaker, though I am stuck with this phone anyway. The Hspa network is actually FASTER than LTE band 17 in my house. I'm just afraid if I travel somewhere and only band 17 is available I might run into some trouble. But then again, 3g or Hspa might still be able to connect.
