Ya, any Android LTE phone even if broken/from a friend/family member, will work (can't be blacklisted though) and you will get all LTE frequencies. Even a GS3 or an old Skyrocket will do for an IMEI. As a side note, I saw some in this thread grabbed the IMEI from a demo unit and then called or had them change it in store. You could have them do an "experiment" by scanning the demo unit to show them that LTE comes back.
[AT&T Galaxy Note 3 General] mircury:
My understanding is that AT&T crippled the radio on their version. They actually removed frequencies from it. Look at the FCC report frequency list below for the N900A and compare that to the frequencies listed in the OP. I don't know if they are blocked in hardware or software this time. With the note 2 you were able to flash some NVM data to get the missing 1700 band back. I doubt it will be that easy on the Note 3.

Having said that Tmobile is refarming areas to 1900 which should give you at least hspa speeds. You must be in an area that is still 1700. My advice would be to sell it and get the T-mobile version.

sorry, yesterday was a reaaaallly long day, but yea i did get the message that a refund was issued from cellunlocker.net this morning. good people, their customer service was respectful and prompt (only on weekdays it seems though). i'm sure they work well for most situations but for some reason my device was one the ones they get trouble with.
[AT&T Galaxy Note 3 General] nxh145:
I 2nd that for this past weekend I waited over 48 hours with no unlock code from cellularunlock.net, they did refund me promptly.
[AT&T Galaxy Note 3 General] indecentspeech:
Here's what I did, it's REALLY easy. I had the same problem as you IE I had called AT&T and gave them the IMEI off my Tmobile Note 3, which wasn't recognized by them. The other problem I had was my main line was coming from an HSPA+ phone (the International Note 1) so I needed to get an LTE Sim card from AT&T. So what I did was I called AT&T and had them make a note on my account that I need a new Sim, then I was just able to walk into a store and get a new Sim without paying for it. After getting the Sim I got my friend's AT&T S3 and wrote down the IMEI. I replaced the last two digits of that IMEI and made up my own. I called AT&T and gave them the modified IMEI and they activated LTE almost immediately.

For a 2nd Tmobile Note 3

I tried UNLOCKFORCHEAP.com last night around 6pm, and its 2 pm now and still have not received an unlock code. That's about 20 hours. I really hope I get it today or I'll have root and use Chainfire's Regionaway App.

In regards to unlocking your phone, I rooted my phone and tried the chainfire app, and it worked! no need to go to Unlocker.com once you are rooted! just --Follow the forums directions exactly--.

But... Is it legal in the US to change the IMEI? for the little I have researched it seems it's iligal with up to 5 years in prison!:(

I wonder if there are any other alternatives...

I found this: http://forums.macrumors.com/showthread.php?t=1202892

So it seems to be legal in the U.S.

T-Mo, is, in fact, "better" than ATT in many respects. In metropolitan areas, LTE has been popping up quickly and the data speed is very good, often better than ATT. I continually maintain service and test all four major carriers and T-Mo, at least in the Los Angeles area, has vastly improved over ATT. The other important element is that T-Mo does not throttle the data speed while on call like ATT does. In other words, while you're on a call, the data rate for T-Mo is almost always faster than ATT.

T-Mo's one significant tragic flaw is that its rural/non-metropolitan-area coverage is very sparse, especially with respect to data. If you go to to outskirts a lot, drive desert highways, visit the wilderness, T-Mo's data will be the first to go. EDGE is unusable. Example: The Interstate freeway 5 that connects Los Angeles to San Francisco will see many many EDGE spots while ATT maintain at least 3G much of the time. Other examples: T-Mo has zero native coverage in Alaska. Also take a look at the middle of the country--Nebraska, Wyoming, etc.--"service partners".

In rural/outskirts coverage, T-Mo is the weakest among the major 4 carriers because Sprint can almost always roam off of Verizon and 1x is still better than EDGE. With PRL tweaks on Sprint, you can roam on Verizon's 3G. T-Mo, on the other hand, does not always roam off of ATT.

The T-Mo's corporate staff told me that the situation will be eased by re-provisioning the MetroPCS frequencies. I do not see how this will solve the problem because MetroPCS' presence is in fact in METRO areas, not rural..

This is why I cannot use T-Mo as my primary phone. ATT, with all its problems, still provide superior overall coverage if you venture out or travel a lot. In outskirts/rural/non-metro, ATT, Verizon, and Sprint all outperform T-Mo.

If T-Mo works well for your life style, great. If you travel a lot, do your research and make an informed decision. YMMV.

I wanted to avoid using Chainfire's App because it mods the modem. I used Unlockforcheap.com and got my unlock code in about 24 hours.

It's not illegal to change your IMEI. The carrier will be glad to do it for you.

What about Straight Talk?
[AT&T Galaxy Note 3 General] lamwong3:
Has anyone tested the reception for the t mobile note 3 on AT&T network? Is there a difference? Sorry if this question was asked before.
[AT&T Galaxy Note 3 General] indecentspeech:
I believe there is a difference in reception. I definitely see better reception with ATT-branded devices on ATT vs Tmobile-branded devices on ATT. I don't think it's an issue with the devices themselves though, I think it's something to do with the modem firmware. I think a firmware update/mod should do the trick. It's not a huge difference but definitely noticable. Ex: ATT-branded device getting -60 dmb and a Tmobile-branded device getting -70 dbm.
[AT&T Galaxy Note 3 General] snovvman:
Straight Talk is a Mobile Virtual Network operator (MVNO). As I understand it, a partnership between Tracfone and Walmart. MVNOs simply use another carrier's infrastructure and "resell" the mobile service. I believe Tracfone has, in the past, used all four of the major carriers (ATT, Sprint, TMo, Verizon). To determine coverage, I believe it is up to the device and which carrier it uses. My knowledge of Straight Talk is limited, and I do not know if the non-MVNO phones get priority. I would search for "straight talk, [device name], carrier" or something of the sort to determine the system it is using and go from there.

Google Play Store update issues?

My two Sprint phones (N3 & S4), ATT N3, and Verizon N3 all automatically updated Google Play Services (to v. 4.0.30) and Google Play Store (to v. 4.4.21) in the past couple of days.

My TMo N3 using an ATT SIM is stuck on Google Play Store 4.3.11 and it won't auto update. I know Google at times stagger the updates and I have not tried to clear data on the app, but I'm wondering if anyone else is seeing the same. If so, I'm wondering if it has anything to do with the hybrid setup. I have been playing with the build.prop ro.product.name, witching between international and T-Mo to see if made a difference, but it did not.

Thanks.
[AT&T Galaxy Note 3 General] snovvman:
PlayStore is up to 4.4.22 now. Instead of waiting for Google to push it, I just downloaded it from here:

does anyone have an extra android lte capable imei for att laying around? Sold my att note 2 and forgot to write down my imei and in the mean time i had activated a non lte phone, now i'm stuck without the lte package... :(

Or alternatively, can any of you pm me your att note 3 IMEI with the last two digits missing and i'll just make those up? I hear that works too. This won't affect anything i just need it so they can provision my data correctly.
[AT&T Galaxy Note 3 General] gubbilo144:
Hello can you tell me how yoi physically turned on the lte,thanks
[AT&T Galaxy Note 3 General] mircury:
No. AT&T has stated that their official policy is to not unlock the bootloader. This makes it very difficult to root the AT&T version. No way has been found yet. That is why the Tmobile version is attractive.
[AT&T Galaxy Note 3 General] flashcity90:
From Home screen menu setting. More networks. Mobile networks. And then network mode and you can select the lte/wcdma/gsm. When I set up att sim it automatically changed to just wcdma/gsm

Thanks. I added that to the guide.

Hey no problem!
[AT&T Galaxy Note 3 General] bob_beringer:
Just got the Note 3 [SM-N900T] from Tmobile, they locked the bootloader on it, along with the ATT version that I bought as well [SM-N900A], both are locked. The policy with Tmobile says that they won't unlock the SIM for the first 40 days after you purchase the Note 3, the sales reps said that we could probably pay other folks to help us unlock in prior to TMobile stepping in.

The international version of the Note 3 [SM-N900], that I bought from onthegosolutions, was really easy to root, was sim unlocked and bootloader unlocked as well (only complaint is not having the high bandwidth from LTE here in the states).

Did a side by side on the TMobile LTE network, the speedtest results were started off at less than 1mb up/down, last test ran at 10mb down and 5mb up, while the international version typically runs 4 - 6mb down on ATT, the N900A's LTE seems to be running about 10mb right now as well, so you aren't missing much in performance, when compared to the hassle of dealing with a locked bootloader and the lack of root, etc...

Hope this helps...

Where did you purchase the N900T from? negri?

Has anyone purchased a N900T from a TMobile retail store and had an unlocked bootloader?
[AT&T Galaxy Note 3 General] wdkingery:
It's not clear if you know SIM-unlocked and BOOTLOADER-unlocked are two different things..?
[AT&T Galaxy Note 3 General] GigDroid:
I am very confused by this. All N900T's from TMobile retail locations are bootloader locked now?! This doesn't make any sense. I understand sim locking but I thought the 900T had an unlocked bootloader, unlike the AT&T 900A which is a locked bootloader, hence the entire purpose of this thread.

---------- Post added at 06:00 PM ---------- Previous post was at 05:42 PM ----------

What I really want to know is: Can I buy a 900T from a TMobile brick and mortar store full retail (should have unlocked bootloader), use cellunlocker.net to unlock the SIM myself, put my current S4 sim card in, update the APN and network settings all myself and be golden? Working LTE and all on AT&T?
[AT&T Galaxy Note 3 General] flashcity90:
I purchased my phone from the local tmobile store and have since then gotten it sim unlocked on att. Im pretty sure i could root it if i wanted to just dont have a reason to do so yet. I DO NOT believe the bob guy really knows what he is talking about. As when you buy the phone from tmobile the sim is locked yes, but they have never locked bootloaders on any of there phones. and for them to start doiing that now makes absolutely no sense what so everrr. plus no1 has stated that it is locked besides him and lots of people picked this phone up today and have rooted it and installed twrp recovery which you cant do if it is bootloader locked.

I will go root my phone and install twrp to hopefully debunk this asinine myth!
[AT&T Galaxy Note 3 General] GigDroid:
ok so, you purchased a 900T from a TMobile retail store, it was sim locked but unlocked bootloader. you then sim unlocked it yourself using cellunlocker.net? I've never used that website before. How does it work?
[AT&T Galaxy Note 3 General] flashcity90:
correct.... I just chose my model number phone then network entered in imei paid via paypal and then recieved the unlock code with instructions 11 mins later in an email.
[AT&T Galaxy Note 3 General] wdkingery:
How much was tmo note 3 from brick and mortar?
[AT&T Galaxy Note 3 General] flashcity90:
Walking out full price with one month of service and 50 dollar deposit 800. you can then cancel service for free and you get deductible back in 2 months time.

i paid full price because if you do the math getting it with an upgrade on att and then paying 90 bucks a month for 2 years plus 300 for phone they make an extra 400 dollars off of you. if you buy full price and then get the same equiv att prepaid plan 2gb lte unlim min/txt for 60 a month you save 400 dollars over 2 years or save 200 dollars over one year

this thread has other people confirming unlocked bootloader http://xdaforums.com/showthread.php?t=2465918&page=8
[AT&T Galaxy Note 3 General] GigDroid:
do you HAVE to get a month of service? I called a local store and they said they'd sell me the phone full retail even though im not a customer but they won't unlock it. if cellunlocker.net works then that's fine. I guess the only downside to going this route over negri is warranty claims? warranty claims would have to be done directly through samsung?
[AT&T Galaxy Note 3 General] les_garten:
Can't you get just a $10 sim card from Negri?

[AT&T Galaxy Note 3 General] GigDroid:
I can't just use the sim from my AT&T S4?

It appears to be software related. Somehow, Tmo lifted the restriction on the throttling. I am using the Tmo Note 3 on Straight Talk, and the speed is the same on a call (give or take) as it is with no active call. pop my sim in my INT S4 and my ATT note 3 and its throttled.
[AT&T Galaxy Note 3 General] bigern79:
Just an FYI, I used www.unlockforcheap.com and got great results. I've used them 3 times now (twice for the N900T) and it is the least expensive I've found.

I can confirm that these instructions work and I am getting LTE speeds in Seattle with my AT&T sim. I'm not able to download pictures via MMS for some reason. Double checked my settings and they all look correct. Any other AT&T users having MMS issues?
[AT&T Galaxy Note 3 General] mircury:
I would delete the APN and add it again. Make sure there are no spaces or periods that aren't supposed to be there. Are you completely stock? And have you tried from multiple different phones?

As usual, my mistake (even after checking APN settings 4 times). Turns out I used "Proxy" instead of "MMS Proxy" for the MMS Proxy settings. Nothing to see here, move along please :o

Thanks again guys, really excited to use this beast!
[AT&T Galaxy Note 3 General] mircury:
So I assume you've tried sending mms messages to your Note 3 from multiple different phones and deleted and re-entered the apn right? Do you still have the ATT phone you are coming from? What phone is it and does mms work on that?

Please attach screen shots of your APN settings on your Note 3 so we can have a look.
[AT&T Galaxy Note 3 General] mrfisch13:
i just used the same settings on an unlocked LG G2 (T-Mobile w/ ATT SIM) and it worked 100% fine, Tossed the ATT SIM back in the unlocked 3 and still not working. I triple checked all the settings and still no results. *The Note 3 works fine with a T-Mobile sim sending MMS*

The actual name of the apn doesn't make a difference. The admin flag most likely does nothing. I don't think anything on our phones uses that data type, unlike mms which is obvious what uses it and fota which is over the air updates which we don't want.

if we use a tmobile note 3 unlock it and use it on att.. when we wanna flash roms we then goto the tmobile thread for them right?
[AT&T Galaxy Note 3 General] mircury:
Yes. The roms in the dev section will be much newer than any ota TMobile provides probably by months. The devs in the Tmobile dev forum can modify international roms sent out by Samsung bypassing the carrier validation and red tape. For instance, Stainless by miscom.
[AT&T Galaxy Note 3 General] MattMJB0188:
Random question, but if I already flashed CWM and a custom rom on my N900T, does that mean my warranty is completely shot? TriangleAway sayd my counter is 0 and binary reads custom. If so, I am still eligible to return my device, as I bought it directly from T-Mobile and have 20 days.

Samsung use to be the best, but now that they've turned into Apple, I don' think I will buy their phones anymore. If I want a locked down phone, I'll just buy and iPhone.

I'd tell Samsung that if they made the damn headphone volume louder, I'd have no reason to flash a custom rom!!!!

So you had an AT&T branded smartphone IMEI listed on your account and were getting good LTE speeds, now they changed the IMEI and you only get H+? Is that correct? Go on eBay and search for any AT&T android device and see if the seller takes a picture of the IMEI #. Write it down and give that to AT&T.

As far as I know, they shouldn't care as long as you are using a smartphone data plan. They don't mind if customers bring their own equipment.

I bought a T-Mobile Note 3 off of Craigslist, and the guy who sold it to me even got the unlock code from T-Mobile. I popped in my AT&T SIM (from my HTC One X), did the SIM unlock, set up my APN, and I was connected at LTE speed. I thought I was good to go, but after about 30 minutes, I lost my mobile network connection and couldn't get it back unless I rebooted. I have tried multiple tweaks to my APN, but the story remains the same: When I reboot the phone, I get anywhere from 5 to 30 minutes of connectivity, then I lose mobile data.

Any ideas?
