[Q] Note 3 AT&T(unlocked) vs international

So I am planning on pre-ordering the N9005. My problem is that I travel frequently between the states and Europe. So I either get LTE here or in Europe.
I have always gotten the international versions for my other devices (S2,Note2,S3,note 10.1 3g). But since I spend most of the year in the states I wanted to get the AT&T LTE version.
However, I don't really want the AT&T firmwares, so I was wondering if I could flash an international firmware on the AT&T unlocked note 3? One of the reasons for this is I know that for instance you could not do tethering without rooting your phone (I am planning on rooting mine) on your AT&T handheld.
I know it's not a big deal, but I want my phone to have the international firmware of my choice, not AT&T's. Thank you

AT&T / T-Mobile compatibility
I would like to know the answer to this as well. Here are the two versions I am eyeing:
Samsung Galaxy Note 3 32GB LTE (AT&T) (Unlocked)
SKU SMGALNTEAUB
3G/4G bands 1900, 2100, 850
LTE Bands 1700, 1900, 2100, 700, 850
Samsung Galaxy Note 3 32GB LTE (N9005 - International) (Unlocked)
SKU SMGN9005UB
3G/4G bands 1900, 2100, 850, 900
LTE Bands 1800, 2100, 2600, 800, 850, 900
Was hoping one of the versions would work on both AT&T and T-Mobile....

Well, the international version won't work on either, you need the 1700/2100 (I.e. 1700) band for the international version to work on either networks, and that's missing from the international version. So I want to know the downsides of getting the att version.

Not trying to start an argument or anything but just wondering, are you positive about that? The international version has the 2100 band as well as the 850 band and I have read in multiple places, as well as hearing during the Samsung unveiling that it would work on AT&T LTE...
Maybe I'm just confused?

Since I am new here, I can't post any links still, but if you go to newegg dot com or to negrielectronics dot com you can see the specs for the international version, they are missing the 1700 band.

Like the other user said you need the 1700 band to get AT&T LTE frequency. The 850 band is for H+ at&t so yes the international version will only work on at&t H+.
What Samsung probably meant by " it will work on all networks" is that they will support all LTE networks if you buy the correct model for your network.

You should only get the AT&T variant if you prove that LTE is faster than HSPA+ in your area. Either use your current phone or use one at an AT&T store and turn off LTE. Run a speed test, turn LTE back on and run the test again, and compare.
It's possible to some international ROMs on carrier branded devices, but not all are compatible. At the VERY least, you'll have to manually configure the AT&T APN, you may also have to manually re-flash radios in order to connect to AT&T towers.
Some crafty devs have made an Aroma installer to do all this stuff while it loads their ROM:

Just know that you're in for a bit more tinkering if you plan on going this route. But there's no reason to go through all the trouble if there isn't LTE in your area or it currently runs poorly.

Im pretty sure by Unlocked they mean Sim Unlocked( u can use on other networks). There is no AT&T units that we know of to confirm whether its bootloader locked or not, but we are only assuming based on recent at&t attempts to lock down their devices.

You're probably right. I think the AT&T will be bootloader locked as well based on the S4 being locked down.

Actually, according to AT&T's website and to their phones' specs, you don't need the 700 band, just the 1700/2100 (I.e. 1700) band.
I believe only Sprint uses the 700 band for lte
Edit: I looked at the AT&T website again, I believe they plan on using the 700 band in the future, but they are not utilizing it now. I might be wrong, so don't take my word for it.

Actually FCC just approved AT&T's purchase of 700 Mhz spectrum so they will utilize the said band for LTE and Wimax possibly

May I ask why t-mobile's unlocked note 3 is not in your list? It appears it will work equally well on AT&T, and there's a much greater chnace of it having an unlocked bootloader. There aren't as many 4G frequencies, so maybe LTE when you're abroad won't always work, but if you want to flash ROMs then an unlocked bootloader is important!
I am in a similar situation to you, and I was planning to go with T-Mobile unlocked. Part of me wants to forget LTE and go with the Exynos, but I fear dev support will be limited.
Thanks for the thread and discussion OP and everyone, because I do not want to regret my choice!
On an unrelated note (no pun intended) - does anyone have experience with Negri electronics? It looks like AT&T will probably start shipping their Notes by October 1st, if not sooner. Do you think Negri will be in the same timeline?

If I get the t-Mobile version then i wouldn't have 4G nor 3G in Europe. Europe mostly operates on the 1900 band for 3G(or at least where I travel to), and T-Mobile's phones don't support this.

I agree. FWIW, I remember reading a few month ago that AT&T released a semi-official statement (it may have been a tweet, or a response to an online article) that all of their android phones will ship with locked bootloaders from now on. Maybe if Samsung really pushed at&t to keep them unlocked, or at least offer a path to unlock (a la HTC's dev program), then it could happen... but I bet Samsung is happy the bootloader is locked; even though they ship the international model unlocked, I imagine they would prefer if it too was locked, but they don't have a convenient excuse outside of the US, where they can just blame AT&T. I LOVE samsung hardware, but looking at exynos documentation and other policies, they don't seem to welcome tinkering.

Darn... but maybe when LTE becomes more prevalent in europe, they'll use some of the same bands as the t-mo version?
I had an HTC One X on AT&T, and eventually a clever dev found a way to get root access and partially unlock the bootloader, but it was such a hassle. For developers, I'm doubt it seemed very hard, but for me, getting it unlocked, and then updating ROMs, flashing radios, boot images, older firmware, newer firmware, trying to find out what was causing a bootloop... It wasn't even worth the headache, I should have just kept it stock (and stock AT&T is pretty terrible when you've been using cyanogenmod for three years). I bought a Nexus 4 soon after, I never want to deal with all that nonsense again!
If only I could wait a couple of months to see what the developer/bootloader situation looks like, I'd probably get the AT&T version if a relatively safe and easy bootloader unlock exploit is found, but I'm too eager to wait, so unless someone miraculously finds an exploit by October 1st, I'm probably going international or t-mobile. It seems like international is the safest bet: 3G coverage everywhere and good support (unless exynos drives everyone away), but I live in DC and the LTE speeds are incredibly good. It's a tough choice!

Where can I buy an unlocked Note 3 N9005 that would work with AT&T?

I have a Note 2 that I bought from AT&T. I want to upgrade to the note 3 but I want the N9005 version because I believe that it will be able to use G4 LTE signal from AT&T. The only place that I can buy the unlocked N9005 version is at Negri Electronics. However it only sell the 16 gb version and I want the 32 gb version. Is there any other place in the U.S.A that sells the N9005 unlocked version?

I'd buy what you're looking for in a heartbeat - if it existed. So far it doesn't. At least not ln any of the N3's for the UK, EU, or Latin America that have been announced. The Korean S-800 SGS4 supports AT&T's bands so their N3 probably will also. But the Korean phones have funky TV h/w and a funky MMS system that's different than Western versions. Rogers' (Canada) version will be compatible with AT&T LTE and may be closer to "virgin" than AT&T's version. The challenge is warranty service both because you'd have to send it to Canada for repair (assuming Rogers' services a phone for a non-subscriber) and because Knox prevents resetting the warranty status if a non-standard ROM's been flashed. Speaking of which, you'd probably only be able to flash Rogers' ROMs via Odin unless their N3 was a "pure" i9505 capable of using international ROMs.
And as someone above mentioned there's some question as to what "unlocked" means with the N3 as there are now regional limitations on top of carrier's locking phones to their networks.
If I find a true international N3 that works on AT&T's LTE that's not regionally SIM locked I'll let you know. Until then I'm sticking with AT&T's version and hoping they haven't molested it too badly.

Thread cleaned.

You can't just say "N9005" and expect to get an answer. "N9005" refers to generic Snapdragon 800 LTE capable version of GN3, but each country and carrier in the world has different LTE bands enabled in that Snapdragon's SoC radio. Find your Rogers here: http://en.wikipedia.org/wiki/List_of_LTE_networks
It operates on bands 4 and 7 - none of the Euro countries' carriers work on band 4, as you can see from the list. AT&T USA, T-Mobile USA and Rogers CA should be LTE cross compatible in most coverage areas, but not all.
If you buy N9005 version with unlocked bootloader - later, when someone makes Odin compatible with GN3 you will be able to flash Roger's LTE modem firmware to your N9005, no matter which country it is from and what LTE bands it currently has enabled

]
Okay well I was looking to buy an unlocked N9005 from the UK. Since none of the euro countries work on band 4, what about band 7? Do both bands need to be working in order to get LTE? The problem with buying this in my country is that there wont be a 64gb option available.

Some carriers, which operate on dual band LTE use one band for upstream, and the other for downstream. If that is the case with Rogers you will have to have a phone with both bands enabled, to get LTE service from Rogers. However, even if that is not the case and both bands 4 and 7 are independent - Rogers has towers all over Canada, and in some regions those towers will operate on band 4, in other regions it will be band 7 and in some places towers will support both. By getting a phone that supports only band 7 you will greatly reduce your LTE coverage area. What percentage of Rogers' network uses what band - those details are publicly available, so you can either Google it or just call Rogers and ask. I would recommend against getting a phone, that supports only band 7, unless you plan on flashing Roger's modem to it later.

This not quite correct. A band, by definition includes both the up and downstream frequencies. Only one band is used at a time. Rogers happens to use band 4 and band 7. One is not reliant on the other. If you are in an area with band 7 coverage (most of Rogers LTE coverage has both) you will be able to use a N9005.

you're correct by claiming each band is self contained and and can carry both, upstream and downstream. However, each carrier owns only a small portion of the spectrum in the bands they operate on, and some carriers do practice using a single band for one way traffic only, in an effort to ease the network congestion and load balancing. I'm not saying it's Rogers - I have no information on that particular carrier, but some carriers do do that. I'm just saying for carriers, who use such practice, in order to get LTE service your phone's modem must have both bands enabled, otherwise it won't register with the network and you won't get LTE service at all.

The OP needs to take into consideration that If he buys from an online retailer an international unit, this unit will need to be activated in its intended region before he can use it in the states.

I've never heard of that. Seems like a problematic setup since the RF properties of bands can vary so much. Seems like you would get in a situation where you have up but not downstream or vice versa.
Yes, you would need a N9005 from Asia, not Europe as those are region locked.

that is a valuable information, which a lot of people, watching this thread could use, not just me. I don't think it will be considered as advertising. People in this thread are looking to buy international GN3, which will work on AT&T in US. If the phone is region locked then it won't work. Therefore, listing the countries, where there is no region lock would be very much relevant to this topic.

Nexus 5 LTE Band support

OK, so far we have some info on the D820 (via the FCC) and D821 (via the leaked service manual).
D820: LTE bands 2/4/5/17/25/26/41
D821: LTE B1, B3, B5, B7, B8, B20
D821 looks like a good match for European, African and most Asian LTE bands, and D820 looks like a match for American & South American LTE bands. China does not appear to be well covered by either model, so there may be a third model if the Nexus 5 is released there.
--------------------------------------
UK:
D820: No carriers
D821: EE (3, 7, 20) 3, (3, 20), O2 (20), Vodafone (7, 20)
US:
D820: Sprint (25, 26, 41), AT&T (2, 4, 5, 17), T-Mobile (4)
D821: No carriers
Philippines
D820: Smart Communication (5)
D821: Smart Communication (1, 3, 5)
--------------------------------------
Please post below with which model is supported by which carriers in your country, and I'll add it to the post.
--------------------------------------
Two models, two spec revisions (with inexplicably lost bands), or the same model with bands 'locked off' for different region (is there a regulatory precedent for this, e.g. WiFi channel 14)? My guess is that the hardware is the same and the bands are locked off somewhere in the firmware, but maybe someone familiar with the chipsets can chime in as to their capabilities?

Its possible that the bands are modem locked. ie with n4 lte band 4. We really won't be able to tell until we get our hands on one.

So officially now, no Verizon love at all.

Sprint supported. Hell yeah.

T-Mobile has just band 4 from the looks of it.

Sorry, I shouldn't say official. It hasn't been announced but the bands listed above do not include Verizon's LTE network. Apparently it supports band 4 wich Verizon is supposed to roll out in the future but everyone else is supported in the US. Even US Cellular just no Verizon from the looks of it.

Ugh thanks. F Verizon. Haha

So there is still a glimmer of hope haha, but knowing Verizon (angry Gnex owner here) and not carrying the Nexus 4, I would not be surprised if they don't support the N5.

I don't know why they just don't do like the Nexus 7 2013 and just put the Verizon bands in there. Verizon won't be happy but with N7 owners, they were able to activate a SIM in another device, then put it in the N7 for service. They just couldn't activate the SIM in the N7.
Verizon is a pain. My GNex is feeling the pain of Verizon but still overall a great device with tons of dev support.
I do remember there being some issues with the GNex release about signal strength and had a technical support nightmare. Plus the problem of Google releasing CDMA source code in AOSP. Not sure how Sprint does it.
Even if Verizon LTE isn't supported now, would it still work for voice service (3G speeds)?
There is mention of the Radio having an adjustable tuner. Perhaps it can tune in to Verizon LTE unofficially.
Verizon uses LTE 13 currently but plans on expanding to 4.

Having Verizon LTE support is still moot if the CDMA voice fall back isn't there. This after all a phone and Verizon doesn't have vo/lte. This makes the the situation with the new N7 different.

In my opinion D820 will also have "Band 3" support.
It's the most used band in the world. And it will be very stupid to sell a Nexus 7 2013 US edition with Band 3 support...and a Nexus 5 without it.
Since, the Nexus is a phone it's more required when travelling than an LTE tablet.
Also, people told me that the FFC doesn't need to approve that Band so we still have no info about this.

I've just dug in Google for a few minutes, and I can't find any info supporting this...the FCC seeks approval on all bands under its perview, to ensure there's no disruption to other frequencies. The fact its a 'world' band is immaterial for release in the US..it would still receive testing/verification.

I am a bit disappointed by the two models, would have preferred a single model that supports all the bands listed (don't know if that is technically possible yet). I travel a lot to the UK and it would have been nice to have LTE while there.

According to the leaked Service Manual, page 6 indicates DCS1800 (Band 3) is supported.

Mmm but the leaked manual is not only for D821?

I don't know how to make it any clearer..but this relies on a leaked manual.

The contest wasn't that the D821 would not support band 3 (as you say, the manual clearly states it), but that the D820 would (the FCC filing made no mention of band 3 being among the supported LTE bands).
The FCC website is inaccessible for the moment due to American governmental sillyness, so it's not possible to see if the D820's details have been updated.

Good catch! Didn't see that...but for the 820, we presently have:

will European z3c work fully on AT&T or should I wait for US version?

I see that the Sony mobile US site has the z3c listed as coming soon. Is it best to just wait for that to come out or will the European version fully support all of the AT&T bands? I'd hate to import a phone and not get the best reception/internet.
I know it was suggested in another thread that it would work with AT&T but then there was some confusion in another thread about the phone possibly missing 1 or 2 bands. Any help from an expert would be greatly appreciated.

I know Sony's white papers have been wrong in the past (Z1 Compact with glass back, grrrr ) but the one for the Z3 Compact D5803 has 4G bands Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20.
I've had a hunt around for AT&T's 4G bands but this seems a but trickier as it seems dependent on region, going by wikipedia it looks like the main bands are 2, 4 and 17 which are all supported by the European version per the above. It probably doesn't help that I'm not from the US and I don't have enough posts to add the URLs, sorry.

I feel like I remember reading back in the day that some companies used bands of the same frequency that weren't cross compatible. It's always made me nervous about buying non US phones. However my info could be wrong.

When I was in the states, I got a AT&T sim card. My phone definitely says that it has the lte bands. Still, it only displayed h+ while I was there. I did not bother to go back to the store and check because the speed was very good anyway. So maybe it's because the bands are different or it was working on 4g but just not displaying it, I don't know.

AT&T must provision your sim for LTE otherwise you'll only receive 3G even if the phone is capable of 4G. Usually they do this based on the IMEI of your device and if it's a non AT&T phone then it won't appear in their database as LTE capable. There are ways for them to manually configure the sim for LTE by contacting support.
The UK model D5803 definitely supports AT&Ts LTE on bands 2, 4, and 17.

Does AT&T have more bands than 2,4,17?

I found when googling AT&T LTE bands that they apparently have also started to use band 5 (850mhz) but that's still supported by the Z3 compact. This was both on AT&T's forums and howardforums but I'm not sure if AT&T need to do something else to enable LTE support on that particular device. I think my own network (3 UK) has to do this as it took a few months for my unlocked Moto X to pick up their 4G network.

From AT&T: https://www.att.com/shop/wireless/byop.html
Refer to the manufacturer's website to verify your unlocked device works with a SIM card on an AT&T GSM network frequency:
• 3G UMTS network 850/1900MHz bands
• 4G LTE network AWS / 700 / 850 / 1900MHz bands

AWS (1700/2100MHz) is band 4 (Blocks A, B, C, D, E)
700MHz is band 17 (blocks B, C)
850MHz is band 5
1900MHz is band 2
The overwhelming majority of AT&T LTE is on band 17. Bands 2 and 4 are used for additional capacity in some markets and/or some rural/smaller market coverage. I'm not sure they've rolled anything out on band 5 yet, but even so the Z3c has that covered.

OK,
thank you very much for the additional research. It seemed like that was the case but I don't trust my own opinion since I haven't done any real looking into this type of stuff in like 4 years.

To answer your original question, as far as we know there is no US model of the Z3c, only the EU D5803 and Asia D5833. If Sony sells it unlocked in the US it will probably be the D5803.

In preparation, hopefully I'll have it in a week.

Subscribing since I'm very interested in this phone and my service provider is AT&T

Works great. I live in both NY and San Francisco, and I get LTE everywhere on AT&T.
I imported the D5803 (EU) model through Expansys.

Yes. Just make sure to get the d5803 model.

TMobile Note 5on AT&T?

My Tmobile Note 4 runs on AT&T unlocked. Will I have similar luck with a Tmobile Note 5 on AT&T if I can get it unlocked? One thread points to a missing Band 17 on the Tmobile device, but I don't have a definitive answer. Looking for the benefit of rootable and unlocked bootloader.

what exactly is Band 17 used for though? 2G, 3G, LTE, Talk/Text?
is your N4 missing Band17 as well?
why not pick up an unlocked intrnational version?

It is missing band 17, which is AT&T's low band.
Otherwise, it works great on AT&T.

I pulled up an LTE band tester and I am using band 17 at my house on my N4. I take it that means the TMob version is out.

That's right, the TMO Note 5 left out Band 17.
