I have the GT-I9305N, which apart from the standard 1800 and 2600 MHz bands available on all 3 phones has the 900 MHz band activated in place of the 800 MHz band available on the GT-I9305, whereas the GT-I9305T seemingly has only the 1800 and 2600 MHz bands.
So is the LTE chip in our 3 phones the same chip or are there different variants? And what is the point of the GT-I9305T if the only difference is it has one band fewer than the other two, I mean why not just sell the GT-I9305 in that case? Wouldn't that make more sense out of a manufacturing aspect? (fewer variances means fewer configurations and less work for a manufacturer, I hope this is obvious to people)
I mean unless the point is that the GT-I9305T should only be usable on carriers which have networks with the correct frequency bands supported, making re-sale less likely. That is literally the only possibility I consider likely. What are your thoughts?

Probably there is some legislation about low frequency bands in Australia, I don't know... But AFAIK i9305T was made for Telstra Australia, as i9305N was made for Sweden where Tele2 (COV) and Telenor (Voda) are working at the 900 and 2600 spectrum.

I haven't looked into it but don't really think there is much difference. I have the 9305T which from what I have seen appears to be a Telstra only model as I think both Optus and Vodafone in Australia sell the 9305 (I may be wrong but remember seeing Optus with 9305 not 9305T). I have not tried a 9305N rom but both 9305T and 9305 roms work fine on the 9305 only difference lately is signal strength. Status bar reads one bar less if using a 9305 modem. I am pretty sure the 9305T would have the 900 range active as Telstra use both the 850 and 900 range.
I do remember reading some time ago that Telstra are a bit more picky with testing the phone on making sure the software is more suited to their network and being Australia's largest telco provider I think may have sway over some manufacturers who are willing to make multiple varients to get what they want. Just my thoughts could be wrong

I'm not from Australia, so i cannot say much about your telco providers. But here in Brazil i only saw the GT-I9305T been selling by Claro (wich includes mine). As i could search, Claro works with the 850Mhz (3G) , 1800Mhz (GSM/GPRS/EDGE) and 2600 MHz (4G).
On Brazil - as the site from Claro says - 4G only works yet with the range 2,5GHz - 2,69GHz.
== Sorry the bad english ==
For those that buy a GT-I9305T with Telstra firmware and try and use it on another telco's network, calls and SMS will work but MMS and Data will not due to the CSC.
The solution is to download the stock Australian Firmware and use Odin to flash
For example
PDA: I9305TDVBMB1
CSC: I9305TTXSABMB2
The symptom is the missing H+ etc in the status bar next to the signal strength bars.
My phone is GT-I9305T, will it work the same if I flash the GT-I9305 rom along with RIL + modem from GT-I9305T?
I have a gt-i9305N
I think the N stands for Nordic, I live in Sweden and have Tele2
And I have only flashed the rom. No need to flash your radio if it already works fine.
Flashing CM rom won't touch your radio and rightfully so.

I used a i9305t with stock Telstra firmware on the Optus network for a little while before I rooted it and changed roms. Data worked fine...
Sent from my GT-I9305T using xda app-developers app
I know this thread is old but incase anyone else is wondering. Its the modem thats different, the 9305T runs on Australian frequencies and adds the 850 band which is Telstra NextG network.
Hope this helps.

Yes. just flashed the german 4.3 ROM on my I9305T - even the 4G data worked, but data speeds improved greatly when I flashed my carrier's current baseband/modem.
The hardware in the variants are the same, it is just a carrier/manufacturer agreement to limit non-carrier provided firmware.

I agree fully. I too have a GT-I9305T LTE from Telstra. I had the 4.1.2 firmware running. I too downloaded the latest Jelly Bean 4.3 for GT-I9305 from Germany (I9305XXUEMKC_I9305DBTEMJ4_DBT). I honestly had my concerns. Compatibility for the network being one of them. I did alot of research and decided to take the plunge. All done and I am more than happy with it. The dowload speed jumped from about 6mbps to 60 mbps. Not sure why but I dont really care its faster than broadband that I'm stck with at the mo. Anyway. GT-I9305 firm works fine in a GT-I9305T.

OK, I did a crap load of research on this earlier in the week because I'm in the process of buying a few I930x phones for the family via eBay.
My understanding is that the hardware is identical but the ROMs in use on each version may affect network operability.
The issue gets clouded because data you find here and there on the interwebs tends to have conflicting information about the phone's specs.
Regardless of what specs you read on GSMArena or elsewhere, the ROMS for phones that Telstra and Optus provide are customised for their requirements.
The hardware may be identical to the that described elsewhere on the web, but the software isn't necessarily so. ROMs for the i9305 and the i9305T are also customised by other network providers around the planet, and thus may differ from the vanilla "International" versions.
I'll restrict my reply to LTE (4G) here, as all variants of the i9300 and i9300T appear to be compatible with 850/900/2100 3G UMTS spectrums used by the three Australian networks.
Both Telstra and Optus currently operate 4G on the 1800 spectrum.
However, Optus operates additional 4G on the 2300 spectrum for its "4G Plus" customers - see Optus's notes at optus[dot]com[dot]au/network/mobile/4g
Telstra does not operate on the 2300 spectrum and has no requirement that its handsets operate there. Hence, I would be surprised if Telstra feels any desperate need to incorporate access to the 2300 spectrum in its ROM.
On the other hand, Telstra has "... also been using some 2100MHz spectrum to provide extra capacity on [their] 3G 850MHz network using the latest generation of network radio equipment known as Software Defined Radio. As the number of LTE devices that are capable of LTE2100 increases, [they] can simply change these cells from 3G to 4G-LTE via software. This will help [Telstra] manage 4G capacity until [they] get...new spectrum. See Telstra's notes at exchange[dot]telstra[dot]com[dot]au/2013/05/07/mobile-spectrum-auction-result/.
So, both the i9305 and the i9305T will work on the 1800 spectrum, but the i9305T may or may not work on the 2300 spectrum and the i9305 may or may not work (for 4G) on the 2100 spectrum.
Theoretically, the i9305T is also optimised for the specific band within the 1800 spectrum that it needs to operate on. However, in practice, the handsets are tolerant enough such that this is not an issue.
Handsets provided by Telstra and Optus will definitely work on the relevant spectrums their respective networks utilize. i9305 devices provided by third party providers require investigation on a case by case basis.
However, the situation is about to become more complex.
At last year's ACMA auction both Telstra and Optus bought additional bandwidth in the 700 and 2500 spectrums for expansion of their LTE networks. See Telstra's info here exchange[dot]telstra[dot]com[dot]au/2013/05/07/mobile-spectrum-auction-result/ (again) and ACMA's info here www [dot]acma[dot]gov[dot]au/Industry/Spectrum/Digital-Dividend-700MHz-and-25Gz-Auction/Reallocation/digital-dividend-auction-results.
In the Telstra link provided above, Telstra also says "Firstly we’re seeing new devices that support the LTE900 MHz band (another low frequency band) so we’ll use this in areas where coverage and capacity makes sense. We’ll also deliver Australia’s first LTE-Advanced network and devices using LTE900+1800" and "We’ve also been using some 2100MHz spectrum to provide extra capacity on our 3G 850MHz network using the latest generation of network radio equipment known as Software Defined Radio. As the number of LTE devices that are capable of LTE2100 increases, we can simply change these cells from 3G to 4G-LTE via software. This will help us manage 4G capacity until we get the new spectrum."
So, in the not-too-distant-future, Telstra 4G devices will operate on bands in the 700, 900, 1800, 2500, and possibly 2100 spectrums, whereas Optus 4G devices will operate on bands in the 700, 1800, 2300 and 2500 spectrums,
A summary is here mobilenetworkguide[dot]com[dot]au/australian_mobile_phone_frequencies.html"]here[/URL].
The big question then is how are customers going to get firmware upgrades so that there devices can take advantage of the spectrum changes.
It would be reasonable to assume that Telstra and Optus will provide updates for newer devices they have provided. However, neither will provide firmware updates for devices acquired from elsewhere. Optus ROMs won't take full advantage of Telstra's network, and Telstra ROMs won't take full advantage of Optus's network. Other ROMS may or may not provide access to all the relevant bands,
So, Telstra may provide updates for i9305T units it has provided, and Optus may provide updates for i9300 devices it has provided. In order to receive these updates you will need to be running the appropriate Telstra/Optus Australian ROM on your device.
Devices acquired from 3rd party providers, whether they are i9305T, i9305, or anything else, will probably be left out in the cold.
You could, of course, root your device and load a suitable ROM that way. I could do it, you may be able to do it, but 99.5% of people out there would not be able to do it. And I really couldn't be bothered to do it on multiple handsets.
So for peace of mind, given these imminent changes I'm sticking with Telstra branded i9305Ts. It just seems to be easier that way.
PS to mods. I saw the message "To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages, yada yada yada" However, I'm not spamming and the information I have linked to is on-topic, but it is obviously too voluminous to incorporate into the post. Hence I have taken the liberty of modifying the URLs of the links as a compromise, so that they are not hotlinks but people can still find the sources. I don't mean any disrespect. It's just that I went through this exact same process earlier this week, and found the source information to be really helpful

Question, I'm trying to install the 4.3 ROM also, but so far haven't been able to find it available for download. Can you link to where you found it by any chance?
Edit: I was looking for this specific ROM, as others had tried and tested it. I have found other 4.3 ROM's for the I9305, but if anyone has a link to I9305XXUEMKC_I9305DBTEMJ4_DBT that would be nice
Currently I have the Note 2 with AT&T. I will be upgrading to the Note 3 when it comes out. However, I am not sure which version of the Note 3 to get. Should I get the International version or the AT&T version. I think the international version has the Samsung CPU and the AT&T version has the Snapdragon 800. Would the international version work with AT&T LTE cellular? Would the international version work with T-Mobile LTE cellular (just in case I want to switch)?
Which one would give better battery and faster speed/graphics?
Correct me if I'm wrong, but I'm pretty sure the international version will only run on AT&T 3G. I am in the camp that prefers the Snapdragon 800 to the revised Exynos 5, too. I'd opt for the AT&T version (Although personally I'm giving T-Mobile a shot this time around)
The N3 will be my first "carrier" phone on AT&T in two years. I'm not thrilled and depending on what it's like using it I may sell it on eBay and get a HSPA Octa. Here's my thinking:
Pros
I've been fine with HSPA+ on my previous phones and use to pay $10 a month for unlimited data through the "non-smartphone" loophole that applied to phone's AT&T didn't recognize. That party's over. So now I'm paying for LTE and not able to use it. So with AT&T's N3 I'll finally get what I'm paying for and even get LTE-A when they start to roll it out; supposedly this year.
The international N3's are insanely expensive. Negri and NewEgg have the Octa's at $779 and up. On Next it's $35 a month, I have no contract commitment beyond the phone's payoff, and I can sell it on eBay if I want something new.
Service and repair. Whether through Asurion or SquareTrade getting a carrier phone repaired/replaced is easy compared to jumping through hoops to get an international version (non-warranted and non-supported by Samsung in the U.S.) repaired.
Cons
God knows what AT&T's done with the s/w. We know there will be tons of their specific bloatware. That doesn't concern me because it can be disabled and with 32GB of NAND the space it takes up isn't a big deal. My big concern is their modifying, neutering, or completely removing some of Samsung's stock apps and features. I can't root my phones because I connect to secure networks so I'm pretty much stuck with what comes out of the box. I'm scared at what's coming out of AT&T's box.
I loved being able to use any multi-CSC ROM on Samfirmware or Samsung-Updates to keep my unrooted phone always current. I've probably had a dozen updates on my N7100. Now I'll be dependent on AT&T. That alone could end up pushing me to an international Octa N3. Also, to support the new features of Knox, Samsung's seriously altered and locked down the bootloader. So who knows what impact that'll have even on international N3's when it comes to updates via Odin. I used to root my phone when I wanted to do someting to it (EG: Google Wallet) and then unroot afterward and run Triangle Away. That ship sailed mid-year and with the Knox enhancements isn't coming back.
AT&T's modified radio may be crappy and I travel a lot internationally. Also I'm guessing on Next the device can't be unlocked until it's paid off. The only reason this is acceptable in my case is I'm getting a 3G (Octa) Note 10.1 2014 which has a dialer and I can use it in situations I need to pop in another carrier's SIM and/or the AT&T radio isn't working well.
Dev support is going to be limited on the AT&T N3's compared to the international versions. It'll probably still be strong but not as simple, timely, and robust. It doesn't apply to my un-rooted situation but something for people to consider.
The moment I find a S-800 international device that's quad-band GSM/UMTS and supports AT&T's LTE bands I'll buy it and sell my AT&T version. So far the EU and Latin American versions of the N3 don't support AT&T's LTE bands. The UK N3's LTE bands haven't been announced yet but I don't have high hopes. There's a chance a Canadian carrier will leave their version of the N3 unmolested and with the same model number as the international version and that it would support AT&T's LTE bands. That would allow it to be flashed like a non-carrier Samsung phone via Odin (with the possible exception mentioned above) and still get LTE on AT&T. Same thing for Claro in Puerto Rico. I'm not sure about the flash part but even an unmolested Canadian or Pueto Rican N3 with AT&T's LTE bands might end up being better than whatever AT&T does to their version.
All just my opinion of course.
I'm leaning towards either international or T.mobile or Canadian version. The att s4 can't be bootloader unlocked and new update patched the root. I'd hate to not have options on such a power device that I could potentially last for a couple years.
I had the note 1,note2,and now using the galaxy mega until the note 3 hits the shelf.I'm up in the air as well in deciding whether to keep my at&t note 3 or sell it and go international.I'd rather keep the at&t note 3,but who knows if were going to be up ****s creek with no root,are how long or ever going to get root method.I guess I can deal with no roms,but no root forget it
I thought that the international N3 (9005) with the SnapDragon 800 would be compatible with AT&T's LTE bands, no? Wasn't this mentioned during the presentation last week about the N3 supporting global LTE bands? Couldn't one just buy/import an international 9005 which was released in a country whose LTE bands match that of AT&T? Would this work?
I guess we'll know soon, but my own need would be for a variant which supports my home UK 4G network (EE most likely) plus USA AT&T LTE for when I'm in the states. Preferably bought in the UK for my UK carrier because of the discounts.
I thought the release event said they were going to support all bands in one device, but I've no idea if that's actually going to be true of the version you get at your local phone shop.

I've beeing researching for hours, and accordung to multiple sites, like this one the international N9005 version will support LTE 2100/1800/850/1600/800MHz (Bands 1,3,5,7,20). This does not include AT&T, whose LTE network operates on bands 4 (1700Mhz) and 17 (700Mhz). I hope these frequencies vary by region, like many sites mention, but I have my doubts we'll get lucky to see international N9005 with LTE bands 4 or 17.
Here is a list of countries, which has partial LTE band overlapping with AT&T. None of these support both, bands 4 and 17, which is what AT&T uses:
Argentina - 4
Colombia - 4
Ecuador - 4
Paraguay - 4
Peru - 4
Uruguay - 4
Canada - 4
Puerto Rico - 17
Since Note 3 has LTE radio, capable of supporting up to 6 bands, the only hope is that one of these carriers will pick up a version, where the other missing band is tossed in without any real purpose behind it, just to keep things interesting. For example, AT&T branded GN3 needs only these 2 LTE bands, and yet the device is LTE penta band.
Also, keep in mind we dont even know what band will AT&T use next year, when LTE-A goes live. I believe AT&T owns spectrum in 1900Mhz and 2100Mhz areas, and in the process of acquiring more.
EDIT: I'd like to clarify my statement about GN3 radio supporting 6 LTE bands. What I meant is some carriers will offer a version, which has up to 6 LTE bands enabled simultaneously. The actual hardware capability of Qualcomm's RF360 Front End solution is universal 2G/3G/4G support - the radio is capable of operating on *all* LTE frequencies.
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.

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.

Do you have a link for a source, where you got that information from? Or better yet - list of countries/markets, where GN3 will not be region locked?

Email me or hit me me up through my site. We're a retailer/wholesaler, not sure if I'm allowed to post about that since it would be "advertising".

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.

N9005 from HK or Singapore (perhaps others too) will work.
The South American N9000 are region locked to South American, North American, carribean etc. SIM cards (western hemisphere).

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
Click to expand...
Click to collapse
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.
I noticed on the specifications list that the international LTE version has some of the same LTE bands as the Verizon LTE version. Would the international LTE version of the S2 be at all usable on Verizon's network?
Which variant? I don't remember seeing any international variants with LTE B13 support. In any case, there is no CDMA in the international variants and I strongly doubt you could use them on Verizon.
Is B13 the one Verizon uses in the U.S.? I was just looking at the one on amazon listed as "international LTE". I didn't realize there were multiple versions of that. I also got the impression from reading around here that Verizon's LTE was more or less the same as everyone else's because CDMA just isn't capable of the modern band width requirements. That was a long time ago though and I may have misunderstood.

Yes, B13 is Verizon's main LTE band in the US.
You say main as if there are others. Does Verizon use other bands too? At all?
In certain areas Verizon also supplements coverage with bands 2 and/or 4. Eventually they are also expected to deploy on band 5.
Thank-you for repeatedly taking the time to answer my questions. I appreciate it.
I live around the Baltimore area so I imagine they might have need to supplement with the additional bands around here. The international Tab S2 being sold on Amazon does support bands 2, 4, and 5. No 13 though. So assuming Verizon has deployed band(s) 2, 4, or 5 in the area the question remains: Would the international Tab S2 receive LTE service? Someone must have tried it by now.
Have any other "international" samsung devices been able to receive Verizon service in the US?

What you are trying to do is just a bad idea unfortunately. Even if you could activate it (which I doubt you could in the first place), the supplemental bands are high frequency bands and you may well run into situations where you won't have any coverage at all because you couldn't pick up band 13 (which is a low frequency band that penetrates into buildings much better than bands 2 or 4).
Why not just buy the Verizon model?
That is very helpful and insightful info. Thank-you.
For my purposes the tablet will be used mostly for entertainment purposes. I have a galaxy S4 (mdk bootloader) phone for serious communication needs. I was just thinking that there may be a performance advantage if I could swap the sim card from my S4 into the tablet and get internet (where available on bands 2, 4, 5) directly from LTE rather then from the wifi hotspot on the S4. I figured it may not work all the time but if it did some of the time it would justify buying the device with capability, all else being equal.
I would absolutely buy the verizon model if it wasn't boot-loader locked. It sounds like noone has been able to hack a ssmsung/verizon device for the last few generations so I'm not holding my breath.
(The info you've been giving will also be handy when it comes time to replace my & wife's S4 phones which will probably be in the next year.)
Oh, ok, I see, your issue is with the bootloader. Yeah, that's a problem.
I am also using an S4 on a CDMA carrier (Sprint). Planning on getting a Nexus 5X soon. It's nice in that unlike Samsung and their plethora of variants of the same device for each country, there is just one Nexus model for all carriers in the US, and it's also unlocked right out of the box.
