Trade T-Mobile N1 for AT&T N1?

I bought a used N1 on eBay. I totally wasn't even thinking about the fact that there are different models of the phone for different carriers. Turns out I have the T-Mobile N1, but I have AT&T service currently.
I assume that there is no kind of mod/firmware to get it to use AT&T 3G, and that it's the hardware that limits me to T-Mo? Probably more than some custom firmware or something could fix?
That kind of sucks, if so. I doubt anyone would have an AT&T model, looking for a T-Mo model, eh?
Thanks for any help, if it's even possible..

Have you looked at the seller's return policy?

No returns accepted, as stated on the item page.
I can live with it (in remorse)..
The seller didn't mention what model it was at all, either.
I don't suppose Verizon uses the same bands as T-Mo?

No, they don't. T-Mobile and Verizon use totally different radio technologies.
Go onto the Marketplace forum on XDA, and trade/sell it through there.

Put your sim card in it

Post it for sale locally on craigslist to finance a unit with the AT&T radio.

Also if you have trouble locating the AT&T compatible N1, you may also consider the Telus version of HTC Desire. Largely the same hardware, AT&T bands, but no Euro 2100 band.
Possible bonus: AT&T does not know the IMEI of Telus Androids, and might not force you to a higher cost smart phone data plan.

Thanks for your input, guys.
I'll try first to sell it locally via Craigslist.

I really think that it will be much more difficult
since they discontinued the Nexus One, and provided it through the developers only,
it has always been the T-Mobile version which is quite disappointing....
the AT&T version seem to just disappear from manufacturing all together
point I am trying to make is that it the AT&T version should be much rarer and possibly worth more on the market since there are less quantities of it
it sucks my friend I feel for you...

How is the T-Mobile N1 different from AT&T model?
Sent from my Nexus One using XDA App

Different radio frequencies and limited availability. Otherwise identical.

I've done the exact opposite...got myself an ATT N1 while on tmobile...hahaha

hahah. I've since sold my T-Mo N1 on eBay and bought an AT&T N1 from Craigslist.. got a sweet deal, too!

wait wait a sec
If you Unlock the S off on the nexus one Tmobile. You can use a At&t sm card with out a problem. I UnloCked the S off ON the mytouch 4g AND IT works on At&t s network. HMMMM. Wondering if it works.

Yes, it will function on the network. The issue is that the radio hardware is built for specific frequencies, which differ between the T-Mobile and AT&T models.
You can use one phone on the other's network just fine as a phone, but you will be limited to 2G data speeds, as AT&T uses 850/1900MHz for their 3G data and T-Mobile uses 900 1700/2100MHz.

Umm, nobody uses 900 MHz for cellular in North America... that spectrum is not allocated for that purpose here.

You're right, my apologies. The fact of the matter (that the hardware is incompatible between the AT&T and T-Mobile networks) remains intact though.
Correct 3G data frequency information, as best I can make it out:
AT&T uses 850MHz and 1900MHz.
T-Mobile uses 1700MHz and 2100MHz.
900MHz and 2100MHz are used primarily in Europe; a phone made for European markets will have a better chance of being fully compatible with T-Mobile's network in the states based on sharing the 2100MHz band.

Closer but still not quite
Read up on the AWS band. European phones will not get T-Mobile 3G at all without 1700.
But in the specific case of the Nexus One, models sold in Europe do have AWS.

I just got the mytouch 4g and i wanted to sell my nexus one. But i wanted to double check and see if i can sell it to someone on the at&t network. I currently have tmobile. I thought the S-Off was to completely unlock the phone. So u can switch between carriers. Didnt know the frequency would be different. thank guyz. Damn u HTC.

What kind of shape is your T-Mobile N1 in?
I'm actually in the process of switching to T-Mobile, and I have an ATT model that I would potentially be interested in trading, but it's definitely not mint.

[Q] S4 SGH-I337 or SGH-I337m? AT&T or Rogers?

Sorry moderators, put this in the wrong section last time! Feel free to delete previous post!
I spend 50% of my time in the US and 50% of my time in Canada and have a contract with both AT&T and with Rogers.
I am going to buy the S4 soon. Should I get the SGH-I337 variant with AT&T or the SGH-I337m variant with Rogers?
In about 14 months, I will be back in Canada (on Rogers) permanently. So far, I am leaning towards the AT&T variant due to greater rom availability, but I am worried about whether the S4 will work on Rogers 3G bands and LTE network.
The reason I am worried is that I am currently using an unlocked Sprint BB Tour 9630 Quadband on Rogers with specs:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 2100
CDMA/EVDO Rev A 800/1900
And the Roger's EDGE network barely functions on that phone (many disconnects).
I am a little unfamiliar with network bands, but can you let me know if the phone's 3G radio and LTE radio are identical across Rogers and AT&T?
I read somewhere that Rogers S4 uses 2600 MHz LTE Band and AT&T uses 700 MHz LTE. Is this true? Or does this phone have both LTE bands built in?
Thank you!

After a quick search, I believe both phones should have identical network capabilities.
So you should be able to get LTE and 4G access on either of the networks using either of the phone variants.
The 'M' after the model number is definitely a Canadian carrier thing and it makes no difference. I have a Galaxy S2 from Virgin/Bell which was sold in Canada as GT-i9100M but it was identical to the international GT-i9100. So much so, that I was able to flash the ROM for the international GT-i9100 on my phone without any modifications or complications.
Hope it helps! Or a more senior member can chime in and correct me!

i would recommend going with the rogers i337m. the only reason that there is more roms for at&t version is that there is a stronger demand for them. but any roms meant for i337 will also work on i337m.

Why would you choose the Rogers version?

if you were thinking about getting the s4 soon i would go with att variant like you said because of the rom availability, but if you were going to wait, let say a few weeks to a month i would just get the i337m because samsung will probably push another update to ruin djrbliss work to unlock the bootloader. just keep checking back to see if any update gets pushed through and youll be good

Hmmmmm. Thank you all! I may just end up getting the 32gb model from AT&T, since I know the AT&T model has the same radio bands built in for 3G and LTE. I'll just hope for an unlocked bootloader!

AT&T has a locked bootloader, but you can get it in 32GB. However there are works underway to get around the locks.
Rogers has an unlocked bootloader but only comes in 16GB. Unfortunately there are no ways that I know of to get around the lack of internal space and JB does not let you install apps on external SDcards.

Perfect. I'm going to trade my Blackberry Q10 for the AT&T S4 32gb.
Thanks!

Which model to buy for full freedom

I am on ATT but I am tired of ATT BS and locked bootloaders and ROM work arounds. I want to be able to use international ROMs. Plus I want to have my ATT LTE.
I want freedom to have me device my way and with any carrier sim. With this said money is not the issue. So what do I buy. If I am reading things right the answer is a T-Mobile Version and then cancel the contract and put my ATT SIM in the Note 3.
Can anyone confirm or advise?

Want your cake (international version) and eat it too (non-international LTE) AND complain because getting both requires a bit of work? LOL
No carrier is going to let you have full freedom w/o you going behind their back (i.e. unlocking bootloaders and custom ROMs)

The T-Mobile appears to have an unlocked Bootloader and unlocked if paid in full. So that sounds like a clean unit to me. That I am free to load Intonational ROM's etc...

If you don't mind 32GB only of internal storage, which effectively translates into ~24GB of user available space - T-Mobile GN3 is your best bet. Pay in full, to get it unlocked and put your AT&T sim into it. Then you will have unlocked bootloader, no carrier network lock, no regional lock and it will work with AT&T LTE. You will be able to use international roms as well, as long as they're not for the octa-core version. You will also be able to flash AT&T modem to it, if you wish.

I just got the T-Mobile Note 3 from Negri (unlocked) It is $689 with no tax here in CA

I want to order a Note 3 from Negri to use it with AIO. I would like to have the unlocked bootloader but I'm worry about something I read in another thread here (Note 3 Carrier Selection):
"The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals."
What if ATT is using 1700 in my area for LTE? I will have the unlocked bootloader and no LTE? Where can I find what frequencies ATT is using in what areas? I made some searches without luck.
Any help will be appreciated.

Some search without luck? You've got to be kidding me! I have personally posted AT&T's LTE frequencies in at least 3 threads in Note 3 forums. It takes about 2 seconds to google a wiki page with LTE frequencies by carrier worldwide...FYI AT&T operates it's LTE network on both bands 4 and 17 in most areas. However, I don't understand why do you think there is a problem with AT&T & T-Mo using the same frequency in a certain area. There are 2 absolutely independent carriers, each with their own towers and your phone will get service from a carrier, based on whatever SIM you put in. What difference do these overlapping frequencies make to you?

I did find information about the frequencies used by each carrier. What I was looking for is what frequency is used in a given area, say near my house. Maybe that is not the right question since I'm new to all this problem.
In another thread (Note 3 Carrier Selection) people is recommending to buy the TMobile version over the ATT version even if you want to use it with ATT (AIO). Because the bootloader in TMo may be unlocked. But then cheols46 posted this:
The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals.
I have 2 HTC One from each carrier and while AT&T version will pick up LTE at my house with the AT&T sim card in it, while T-mobile version only picks up HSPA+ with the AT&T sim card. It really depends on the tower frequency you use in your area.

I want to know if that will happen to me if I buy the TMo version to use it with AIO.
Thanks in advance for any help you may provide.

That guy is getting only HSPA with AT&T SIM card because his APN for AT&T LTE is not configured correctly on the T-Mo phone. He probably didnt change the APN settings, or maybe T-Mo stock firmware doesnt even have those settings, since the network didnt support LTE when that phone was bought?
If your phone is configured correctly, and you use AT&T SIM you should get LTE service.

Will you advice to buy the sim unlocked TMo version instead of the ATT version, because of the unlocked bootloader and the support for TMo bands (again this is just something I read)? I'm planning to use it with AIO but after spending all that money it will be good to know that I could use it with TMo if I wanted.

If i were you I'd wait a week or two, until other people do it, and you can find enough feedback on how well things work. The question, you should be asking yourself is not a choice between T-Mo vs AT&T version, but T-Mo vs international LTE version with unlocked bootloader, because getting AT&T one with locked bootloader will severely cripple what you can do with your phone. Keep in mind if you have any LTE version with unlocked bootloader you should be able to flash AT&T modem onto it, once it becomes available, regardless of what LTE bands it currently supports.

I'm sort of forced to get an AT&T version (have unlimited data) but considering taking chance that someone will figure out N3 bootloader unlock for future versions of AT&T roms. Is that wise?

LTE N7, 700mhz, and T-Mobile

Will TMO be bound by the same restrictions re 700mhz as Verizon? My Verizon sold N7 works just fine with my TMO unlimited phone sim (have tried it many times); I'm not sure whether that's related to the above or that T-Mobile just doesn't see it as a tablet. My AT&T Note 8 does not work but that also doesn't have that band.

I don't really understand the question. T-Mobile 700mhz LTE may may not be deployed in your area yet. I know Nyc and its neighbors wont get it until beginning of next year.

[Q] So confused with all the variants

Hi, I've been a S4 user and a very intrigued reader on this website. XDA has taught me many great things about my Sprint S4. I'm now ready to make the leap to the Note 4 and I'm so confused with all of the different models available.
Here's what I want the phone to do:
- I live in the US, and I would like to set up the phone on the Straight Talk or AT&T network and I obviously want to take advantage of the fastest speeds Straight Talk/AT&T offers.
- I am traveling to England in the Summer for a month and I would like the phone to work on one of their networks. (I would like to have 4G, but if 3G is the only compatible band than that's fine, as long as I'm getting some sort of data).
- I travel to Canada on a monthly basis and I would like my Note 4 to be able to run on the Rogers Network and utilize the fast speeds Rogers offers.
Basically, which Note 4 model will satisfy my needs? I just want to take advantage of the fastest bands available in these places. I've been leaning towards the N910H because my understanding is that it is compatible with all of my above requirements. Is this true? If not, which model should I be look at?
Thank you!

I can't say for certain about Rogers Canada, but the US T-mobile variant- SM-910T- is what I have, and you should look into it. Maybe someone with Rogers can chime in about that.
It's 100% compatible with AT&T's fastest LTE bands and most 4G GSM bands used in Europe. It has an unlocked bootloader for easy rooting/ROM-flashing. There is an awesome XDA section devoted to it with some great ROMs and other tweaks. Of course, the major benefit is that if you stroll into a T-mobile store any buy one, it will have a warranty and service options if something were to possibly be wrong with it. Now, you'll need to get the phone SIM-unlocked either through T-mobile directly or an online sim-unlocking service (~ $20-30)
If you wanna spend less in the States, the 910T sells on craigslist, swappa, ebay, etc in pretty large numbers and it's very easy to obtain one in mint condition for a lot less than retail. Obviously, make sure that the device has a good IMEI through swappa.com before buying it used.
I find that lots of people buy the Note 4 and decide to sell it after a while- either they prefer something smaller, or an iPhone, or any number of other reasons like wanting extra cash, but there's tons of em on craigslist here in Chicago.
I bought a Sprint Note 4 in perfect condition from a guy for $350 the other week. Not saying you will necessarily have that type of luck, but just something to ponder.

i use 910U on rogers and AT&T gophone. also used it in the UK, most of europe and asia. this is an exynos taiwan variant with LTE. may not give you the fastest speeds everywhere but its awesome.

In the UK we get the Snapdragon 910F, but the 910H looks good according to the bands I've seen online (I don't know if they're correct mind!)
In the UK different networks use different bands (900, 1800, 2100, etc) for 3G; with some of the bands being shared amongst companies these days. Ideally you want a device that supports 900Mhz UTMS, and the 910H supports the band. The 900Mhz band has better indoor coverage than the higher frequencies as well.
Again 4G is on different bands depending on your provider, but the networks share most of the spectrum at the moment to reduce costs. I believe 4G is on 800, 1800, and 2600Mhz

IDK about LTE, but phones for China/HK will work on our 3G networks. I've tried a few 3G iphone knockoffs and had no issues.
