[Q] Can at&t Nexus One work on T-Mobile? - Nexus One Q&A, Help & Troubleshooting

I'm on at&t. I have an N1 that I bought full price, off-contract.
I've now purchased a Nexus S and planned on giving my Nexus 1 to my girlfriend who's on T-Mobile. I *thought* the phone was supposed to be unlocked but there's obviously lots of confusion about what "unlocked" means.
I've found that t-mobile N1's wont work on at&t 3g, but I've found nothing concerning the other way around.
Could someone give me a clue if this will work?

The phone will work fine, but only on EDGE speeds. There are two different phones because T-Mobile and AT&T use two different frequencies for their 3G networks.

Please read the FAQ, question 13.

Why would you think it could work one way and not the other? If it cant work on at&t because of hardware the same rules apply the other way around otherwise there one only be one model.

Thanks for the replies.
So is there a way I can get this at&t unit to work fully on t-mobile? It appears not. I feel mislead.

no, there is no way to get it to get 4g speeds
you need the tmo nexus 1
the att versions are somewhat rare btw...

Nexus One is not capable of "4G" speeds anyways, not matter what network / device model you use. It has a theoretical max download of 7.2Mbps and does not utilize a HSPA+ radio which is required to access Tmo / AT&T's "4G" network.

[Q] AT&T radio

I tried to get TMobile service for my Nexus one but it wouldn't pick up 3G. So I called Google tech support and they said my Nexus one is an AT&T only nexus one. What's up with that? I thought this was an unlocked phone able to handle any GSM carrier? Can I get it to work on TMobile?

maybe they meant AT&T 3G, it should pickup the EDGE network on Tmo or you are in a dead zone.

it will work on tmobiles edge service, but not on 3G. tmobile and att have different frequencies for their 3G signals. and yes, there are 2 kinds of nexus ones. one for tmobiles frequency, and one for atts frequency.
If I root the phone will I be able to use it on tmobile?
No, Tmobile runs 3G through 1700mhz band & ATT runs 3G through 850mhz & 1900mhz bands. Both carriers use 850/1900mhz bands for gprs & edge network. There is no way to change the frequencies your phone uses because its a hardware issue. This has been attempted many many times with the US always getting phones last.
This is something to determine when first buying the phone. Did t-mobile sell you the wrong version of the nexus?

There is a difference between "unlocked", meaning - any SIM can go in and the phone won't stop it from working, and "correct band for GSM/3G", which is in hardware - the phone has support for X different frequencies of GSM and Y different frequencies of UMTS (3G), and if the carrier you're trying to connect to doesn't work with any of those frequencies and works with some other ones - having a working SIM won't help you, since the phone won't find the working frequencies.
And this question was answered about 10000 times.

[Q] HSPA+ on T-Mobile

Hi, if I were to get an unlocked Galaxy Note GSM, would I have to do anything fancy to get HSPA+ (4G) to work on it?
Would it be as easy as to pop in my SIM card and go to work like on any T-Mobile device?
Please respond back soon because I am trying to buy one tonight off a guy on craigslist, I don't want to get ripped off!

I don't want LTE. I want T-Mobile HSPA+. Will it work by putting a sim card in it?
then you'll need to wait until T-Mobile repurposes their 1900MHz band for HSPA+. I don't know if they're doing it for the whole country, but it has started to happen in some areas already
But it is as simply as popping in my sim card?

Well it's just to make phone calls. It's okay if I don't have internet connectivity everywhere. I am going to be buying it off a guy on craigslist in a place where I normally get service... he's selling it to me for only $450. Kind of nervous that it's a fake/scam.

Sorry but don't count on anything more the edge on TMobile, unless you are really lucky and you are in a 1900 Mhz area. If you want TMobile buy an AT&T Note and you will have to do some hacking to get the radio working on TMobile.

Don't expect the entire US to get 1900Mhz 3G on tmobile, since the radio spectrum is subdivided differently depending on the cities.
Mostly the west coast and pennsylvania so far

So there's no such hack for the international note? I don't understand how an internationally unlocked phone doesn't support USA GSM highspeed. My T-Mobile G1 supports HSPA+.
Does AT&T 4G work with the international Note? I have it now and I'm only getting 2G. It's god awfully slow.
If you want to buy Note N7000 you will get EDGE on Tmobile.

I'm on the Left Coast, maybe should l see if 1900Mhz is in my area.
To be honest, I'm actually happy with me my broadband sim on AT&T. I just had the LTE code added to my account and I got a little boost in speed on HSPA+. I'm seeing 8Mbps down and the speed seems more stable then before. It does seem to be ramping up to max speed a little slower and I have a firm upload cap at about 1Mbps, before I occasionally would hit 1.5 Mbps. HSPA+ does seem to do Skype and Google Voice pretty well, I've been managing to use a a data sim as a phone quite successfully.

The international Note gets HSPA+ on the AT&T no problem. I'm currently enjoying my H+ icon with my Red Pocket sim card.
The International and American Notes have entirely different hardware inside. The American Note has a pentaband radio that can be reflashed for either AT&T or T-Mobile frequencies. The International note does not.

Wrong. The International Note has a pentaband radio. It's the same modem as the Galaxy Nexus GSM.
It just so happens that the AT&T Note shares the almost the same hardware with the T-Mobile S2 which makes it easier in terms of getting the modem from the T-Mobile S2 to work on the AT&T Note. This is why how they got the hack working on the AT&T Note.
This DOES NOT WORK on the Int Galaxy Note as we are running an Exynos/Infineon chip/baseband.
Okay. Instead of arguing with each other about who can spout-off the N7000's and i717's specs most accurately, why don't we just give the OP a simple, comprehensive answer?
Okay. To answer your question, the N7000 (International Note) will work perfectly fine on T-Mobile US. Phone calls, SMS messages, and data will all work perfectly. The issue, however, is not with the services you can get, but the quality of the services you can get. Even though the N7000 is an "international" GSM device, T-Mobile uses irregular frequencies for it's HSPA+ network. Specifically, instead of supporting HSPA+ on a single frequency, T-Mobile's HSPA+ service is divided between 1700MHz and 2100MHz in what is referred to as 1700/2100 AWS (Advanced Wireless Spectrum). Because AWS is a rare and unusual implementation of HSPA+, almost no "international" phone models support it. In most cases, only phones meant specifically for North America support it. What this means, simply, is that the N7000 will never be capable of using T-Mobile's HSPA+ network (unless you have the rare privelege of being in a 1900MHz HSPA+ area).
Now, just because the N7000 won't let you use T-Mobile's AWS HSPA+, it doesn't mean you can't have your cake and eat it too. Granted, it is a small concession, but the i717 is a "more than adequate" smartphone and will (with some minor modification) make neat work of connecting to T-Mobile's AWS HSPA+ network. Preliminary speed tests even suggest that the i717 is faster on T-Mobile's HSPA+ network than the N7000 is on AT&T's HSPA+ network. So, if you're willing to sacrifice the added speed and power the Exynos SoC offers, you could gain T-Mobile 3G compatibility and NFC to boot just by opting for the i717; which, I might add, is only $649.99 off-contract at AT&T.
If I can help clarify any confusion or answer any questions, please feel free to ask. I know there are a lot of people out there who feel very strongly about which version of the Note is superior. However, it's my opinion that when you come across someone who's undecided, you should simply give them the facts and allow them to make their own decision. Passionately mixing facts with opinion only serves to further confuse things.

I don't know the carrier standards very well. After I unlock it, will it work on AT&T and will I get full speed data?
Thanks in advance,

Looks like the T-Mobile version does not have LTE, so that will not work.
UTMS [3G] HSPA(+) [3.5G] should work as the T-mobile version has the same bands as the AT&T version.

The AT&T model seems to lack the 1700 band T-Mobile uses, although all the rest of the frequency are present, and will most likely to work with T-Mobile's upcoming LTE network. If in your area, T-Mobile uses the 1700Mhz frequency, you will have a problem.

I'm going to buy the AT&T model since it has LTE (and is $100 cheaper). It's just a dev phone so it's not the end of the world if I don't get 3G. I'll post here how it goes.

Barry,
You probably bought your phone by now. For whatever it's worth, I just checked with HTC about Developer Edition of the "One" and although it lists all the frequencies in the spec sheet, they said it will only get 2G speeds on the T-Mobile network. Yes, that is 2G. Not 3G, not UMTS either, and of course no LTE. You might be better off with the AT&T version then. On the other hand, I just signed up with AT&T 4 months ago and have nothing but disconnects, dropped calls, garbled speech or no data whatsoever in my area. I have an HTC One X+. To me, it looks like they totally did an awesome job in marketing, when I was getting excellent reception and none of the above problems with T-Mobile. Again, it could be the area or AT&T's network.
I hope that helps.
Take care,
MW

That's what I thought I read elsewhere
what he said above. TMO versions can pick up 3G AWS since most of their network is on that band. ATT doesnt use that band only 1900 for 3G, but since TMO has only started refarming old 2G 1900mhz signal to 3G signal only certain places will recieve 3G signal for TMO on the ATT HTC one.
So far i havent heard of anyone breaking into the radio portions and adjusting the bands. i think people are still a bit sketchy on whether that will work or not. its a pretty big gamble.
your best option is maybe find someone who has the TMO version and wants an international version. and trade?
I have the AT&T One. T-Mobile was sold out and I wanted it the day it was released so I just bought the AT&T One at Best Buy. I have AT&T LTE but I was wanting to use T-Mobile because I have unlimited on that line. I never get 3G though, only HSPA which is weird, or maybe not idk

[Q] AT&T nokia 920 on T-mobile

So without thinking I bought a Nokia Lumia 920 for AT&T off of Ebay.
Now after doing some research I see I may not be able to get 3G/4G.
So I have two things to ask, would flashing another rom on my device help? (I really don't think it will but i'm going to ask to be safe)
Or is there anyway to get 3G/4G working without having to buy a new phone -_-
T-Mobile obtained a bunch of bandwidth that AT&T was going to use, after the failed acquisition attempt. They've used that to roll out network coverage for AT&T's phones, as part of their plan to encourage people to switch. It's not as *extensive* of coverage as T-Mobile's native bands, but it's not terrible. You probably can't get LTE, but you can get 3G and HSPA+ (what TMoUS often calls 4G, especially before they had their own LTE).
I know I get 4G and LTE on T-Mobile using an AT&T 920, but I think LTE only works in certain refarmed areas that use the right frequency. HSPA+ (4G) and 3G appear every once in while and work as well.

sweet thanks for the info.
Yeah, old iPhones used AT&T's frequencies for 3G and T-Mobile uses different frequencies, so you couldn't use 3G. That's not much of a problem anymore, though; even phones that don't support T-Mobile's main bands can use their re-farmed AT&T bandwidth.

T-Mobile refers to it as refarming; that is assuming you have coverage and that's a big if for many of us who are rural and you live in a town big enough to have it then if you're using an AT&T device subsidy unlocked or locked then you will be able to access HSPA+ and I'm not kidding when I say it's fast, faster than both AT&T and Verizon Wireless in Auburn-Opelika, AL and Columbus, GA where I hail from. HSPA+ is not a LTE or 4G technology so it will run on both AT&T and T-Mobile's 1900 band...if AT&T it's HSPA+ everywhere and where T-Mobile has refarmed 1900; it's 3G or 3.5G there too. Otherwise, it's 2G and I can safely tell you it sucks once you've enjoyed HSPA+ and worse T-Mobile has next to no coverage in many places outside most big cities and that's the wrap with T-Mobile.
