I travel internationally a lot and want to get the version with the most LTE band support and the ability to root. In the USA I'm on T-Mobile.
SM-G965U1 (unlocked) or SM-G965U (T-Mobile)? Pros and cons to each?

Both models are the same. The TMO, Sprint, att and vzw models all have the same LTE bands as the unlocked Phones. The only difference is carrier can block bands on there firmware. So you would have to download the other carriers firmware to use the blocked bands.

Both should have the same LTE band support because internally they are the same hardware wise.
The G965U has all the carrier bloat, is network locked, configured for that carrier and will have what ever T-Mobile puts on it.
The G965U1 is network unlocked and doesn't have any of the carrier bloat on it, which makes this the most generically compatible with all the providers (it auto-configures for the provider when you put the sim card into it). This should include what ever bands are necessary for the device to work on the carrier. There maybe some features from some providers that may not work, as those would require the G965U variant from that provider.
As an example, my phone is originally a Sprint variant (G965U) but I had it network unlocked and flashed the G965U1 firmware on it. After inserting my AT&T sim card it autoconfigured for use on AT&T and set the applicable network bands to use. Some of the bands used on the phone now with the G965U1 firmware were never included with the sprint firmware
.
I have the following LTE bands 1, 2, 3, 4, 5, 7, 8, 12, 14, 18, 19, 20, 28, 29, 30, 38, 39, 40, 41, 46, 66 (band 66 is used on T-mobile if I recall correctly)
Originally the sprint firmware had: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 25, 26, 28, 38, 39, 40, 41
The G965U and G965U1 are not rootable as of yet. There has been no updates or information that says when or where it will be.
If you want to be able to root then you would need the Galaxy s9+ with the Exynos model or the G9650 model (that's the only snapdragon model you can root right now)

Errr, I'm confused.
You mean if I have, say, the Sprint version they can choose to have firmware that blocks ATT, TMO, and Verizon? If I was on Sprint and I wanted to use ATT, I would just flash the ATT firmware on my Sprint phone to use ATT bands?
And the unlocked phone has no blocked bands?

That's right att firmware were allow all att bands. No the unlocked model doesn't get anything blocked. I wish the S9 was like the S8 where it would download the firmware right when you put on the sim card

Not being rootable - is this because devs need to wait for Samsung to provide them something first in order to enable root on their phones?
For me, root has always been just about flashing a SuperSU zip in recovery. So I'm assuming that the bootloader is locked and there's no way to install a custom recovery to flash root?
The dev's need to find a way to install the root and then package/make it in such a way as to let anyone install it.
Samsung doesn't provide them way with a way to make that happen. At least I have never heard of that happening.
Hmm... is this normal or typical? Like when a new Samsung phone comes out it takes the community several months to figure out how to root? Or is there a possibility of the G965U1 *never* getting root, meaning some Samsungs get it but other versions never do?

It's normal, the thing with finding a root method is finding a useable exploit (hardware or software) or method to install what is needed to root the phone.
Given Samsung and knox I can not imagine this to be an easy task. So I wouldn't say it will never happen, but it might take a while before the developers have viable method. How long on the other hand is not known.. might be tomorrow, might be next year, might be 2 years. Just takes as long as it takes.

Gotcha. Hmm... In that case I think I might just get the Exynos version as the SnapDragon that's rootable doesn't have much development on it. Plus it seems to support most TMobile bands.
Unfortunately the Exynos version seems to have high power usage issues and people are waiting for a fix from Samsung. Hopefully this will get fixed?
Between G965F (single sim) and G965F/DS (dual sim) are there any differences? Both have the same band support and seemingly the same hardware specs otherwise... so why would anyone ever get the single sim version?

I would imagine it would be up to the individual and each person's need/want/desire/preference/etc... Myself it would boil down to cost and usefulness.
If the cost was the same as the single sim then I probably would. If the cost was higher then I would have to pass on the dual sim phone since I only use one provider (and not two).
FWIW, I've had to sold my G965F/DS and switch to G965U because of incompatibility with T-Mobile. I live in an area where I depend on VoLTE a lot, and the phone is just not usable.

I'm going to regret this if I'm wrong, but I doubt I am, and this reply is motivated only to 1): save the developer from having to field this continued line on this topic,
...and 2): to simply educate (and clarify) the concept the you appear to be having, as well as any other members also confused...
So, to that end, please allow me to interrupt and explain that the SM-G95U is a is a LOCKED bootloader, and as such, to this date of this post, remains unable to be unlocked for rooting on any level. That being said, it IS possible to use ODIN to swap or over-write the necessary software (which is by nature "carrier-specific", i.e., Sprint version, or T-Mobile version, etc., etc...) to open the bands that ARE already physically present on the phones, but which are not functioning, to start functioning. This WILL allow the SM-G960U & SMG965U to be brought from, say Sprint, (I'm using the Dev's example here, to keep my answer focused to the member's specific original question they asked, however, a Sprint to T-Mobile band compatibility/conversion is not all-inclusive or limited to this exact situation, the possibilities abound ad-ifinitum dependent upon a myriad of factors not properly within the scope of this forum) which only use, and therefore only ACTIVATE a sub-set of the bands present on the phone, over to T-Mobile, WITHOUT having root, (which, of course the SM-G965U & SM-G960U are, again, PRESENTLY incapable of being rooted due to the boot loader being locked by Samsung).
I hope my explanation answered your question correctly, and helps you with your understanding of what this variant (the SM-G965U & SM-960U) is and is not capable of as to rooting, and how that does not interfere with turning on the dormant frequencies a potential new carrier might require to deliver service should you opt to change the original carrier the phone was programmed for. It's a nice ability to have that option, and many thanks for the Devs who have taken the time and effort to map that process out down to the custom software they so generously shared above so we may experience their benefits without the cost of their time, efforts, or hard work.
*(The SM-G965U1 and SM-G960U1 is not limited by a locked bootloader, and therefore able to be rooted much easier as a result, which, IMO makes clear that the shameless tech companies could provide a secure platform sans bootlocking the end-user out, who dubiously "own" the device after paying upwards to a thousand dollars for it to be theirs ultimately)

So ya know the 960U and W Can be rooted with locked bootloader And U1 is the same exact model as U and W Just carrier unlocked The U1 Is limited by a locked bootloader just like the rest of the american devices And Is no more easier to root than the other 2 models
Half of what you have posted is completely incorrect and or Unresearched properly.
All three of the device W U and U1 can be cross flashed with any Us carriers firmware as well as each firmware is About 90% compatible to be used on the next once properly sim unlocked which is what is being said here. That also being said Most of these devices come OYN type CSC file allowing one to just insert a new sim once properly sim unlocked and the device will auto configure itself for the new carrier

I have an old M8 lying around that I fired up and had remembered I had rooted it and the bootloader is unlocked.. Is there a way to 'trick' this phone into thinking it's an AT&T branded phone? hboot, etc. and that will allow me to RUU something official from AT&T? I know this sounds really strange and probably stupid but.. I just can't sleep and need something to fill the time.. Can I do it?
Don't think so, radio hardware is different, not to mention the partition layout.

Absolutely not. At least not any way that is known; and your chance of failure is high (with a brick being the possible or even probable result).
As mentioned in the previous comment, the partitioning on the phones is different. If you try to run the RUU, you at best it will fail, at worst it will brick the device.
Most other M8 versions (that don't support CDMA) can be "converted" from one version to another (other exceptions being dual SIM and M8 Eye). But Verizon and Sprint are the oddballs here. Some experienced devs have been messing around with these variants from the start (to try to convert them) with no success.
Perfect! All I needed to hear! Ah well.. it was worth a shot! Just trying to get my account provisioned for LTE so I can get LTE on my unlocked devices.. I've been told, and read, that if I can get an AT&T branded LTE capable phone to just swap my SIM in it.. and let my account provision, then I'll have LTE on any device AT&T or not... Just trying to avoid a contract..

As long as the phone is SIM unlocked (Verizon version is) then you should just be able to put an AT&T SIM in, and enter the proper AT&T APN for service, as long as the phone supports the proper bands. Its irrelevant whether the phone is AT&T branded or not.
Now the underlined bit in the paragraph above is the main issue. The Verizon M8 only supports one of the four bands (Bands 2, 5, 4, and 17) used by AT&T for LTE (Verizon M8 supports Bands 3, 4, 7, and 13). So depending on what band is used in your area, you may or may not get LTE.
But GSM (2G) and HSPA (3G) should work just fine on AT&T.

That's the odd part.. My main phone is the S6 Edge from Verizon.. it's on the AT&T network and I assume my APN is correct.. But it's not picking up LTE and I am almost certain the S6 Edge from Verizon will pick up the correct band for AT&T LTE .. But it's only using the H+ speed.. What's even more strange?? When I throw my SIM into the M8? I get LTE on AT&T and verify with 30+mpbs speeds.. I have no idea what's going on...

Yeah, that is strange. According to the specs for the S6 Edge here, the Verizon version supports the same LTE bands as the VZN M8, and actually some additional bands (2 and 5) that also happen to be bands used by AT&T.
One thing I can think of, is that the VZN M8 in actuality supports some bands that are not advertised/explicit in the specs. It wouldn't be unheard of, as members here have reported some versions of the non-CDMA M8 as supporting some bands not indicated in the specs. And that band happens to be what AT&T is using in your market region. In this case, that band would seem to be Band 17 (the only band that AT&T is known to use, that isn't listed on the S6 Edge specs).
Or the other possibility, is there is just some issue with the S6 that is preventing connection to LTE (but on the same supported band that the M8 has).

As I've already mentioned, its not really necessary to have an AT&T branded device. I suspect the reason you've seen people say this, is that AT&T branding means by definition the phone has all the bands used by AT&T for LTE; since obviously the phone is intended for use on AT&T's network. Since AT&T uses a number of bands (4) and LTE bands being used worldwide has become very un-standardized, its somewhat difficult to find a non-AT&T phone that has all the bands. But they do exist, such as the US unlocked M8, Dev Edition M8, and Nexus devices. Also, I've seen folks used other non-ATT branded phones, which may not have all 4 LTE bands used by AT&T, but the one(s) needed in the particular user's region. Not ideal, but sufficient for some folks.
Another reason why some may say the phone needs to be AT&T branded, is that AT&T tech support won't provide you any support if you have a non-ATT phone. But honestly, I've used non-branded devices (and plenty of folks here have), and this is very rarely an issue. The folks here on XDA will usually provide you better support, anyway!
Of course, your ATT account needs to be provisioned for LTE in order to have that service. Its a simple matter, and doesn't cost anything (just need a smartphone data plan).

Absolutely NO.
What I mentioned above (Post #3) for the Verizon variant, also applies to Sprint (both versions support CDMA - the fact you don't use it is irrelevant). If you try to convert to another version won't work, and will probably result in a brick.
Also, even if you didn't have a CDMA version M8, you typically can't convert using an OTA, it has to be an RUU.

Absolutely NOT. As already thoroughly discussed on this thread, if you attempt to install another version's radio on the Verizon version, it won't work, and you may radio brick the phone (permanent damage possible).
Different radios, different partition layout.
Don't even try it. Experienced devs have tried to "convert" by various methods and mods, and failed.
But there may be other ways (besides flashing another version's radio) to enable the band(s) you want, read on:

You can take a look at the following method, as it claims to enable Band 20: http://forum.xda-developers.com/verizon-htc-one-m8/general/lte-band-7-2600mhz-finally-guide-t2992523
Read the thread, and proceed at your own discretion. I'm not knowledgeable with changing NV values (it doesn't work on "GSM" M8 variants, so does not apply to me). I simply know this thread exists.

All,
I want to knw if it is possible to unlock all the LTE bands for ATT use?
I did somehting similar with my wifes Verizon S7, when her company moved to ATT. (Flashed the ATT Firmware to the phone and all LTE bands worked)
Is this possible now? Can I FLASH a primairly GSM based firmeware to my XT1635-01?
Thanks!

I am only guessing, but based on what I know about the Moto x, and all moto phones seem to follow the same rules now days, but the bands were what they advertised only. There was no way to add any other ones.
I get that... I think the same radio is in the "Verizon" version as the "Retail Unlocked" version...
Just a matter of Firmware activating the additional bands..

Radio's don't unlock bands as far as I know. The phone usually has the bands or it doesn't. Some phones may have some bands that aren't active, and can be "unlocked", but I'm not sure Moto does this.
But radios, that can be flashed, don't affect which bands are available. Neither does which carriers firmware you flash. If you even can without having severe issues. (again, talking moto here. Other manufacturers can be different) Afaik
My question remains, when carrier unlocking an s9 or s9+, is there any way to make it available on different network types like say if the phone started out using a carrier that uses CDMA, is their any way to flash it to utilize t-mobile's frequency bands?
I unlocked two galaxy s9+'s that were on xfinity, which uses verizon towers. The two phones did unlock, but only for carriers utilizing CDMA. I was hoping they would be able to be used on t-mobile after unlocking, but they can't. Only messaging and data works using a t-mobile SIM card. Verizon works fine. SO my question still remains, is there a way to make it work?
I used itekimei .com to have the phones unlocked, as I found they were suggested here on XDA. And they weren't really able to answer my question either. They said it should work with t-mobile, but the conversation ended with "t-mobile is having problems with unlocked phones." This is super frustrating trying to get an answer.
Edit: I found this forum https://forum.xda-developers.com/galaxy-s9-plus/help/sim-unlocking-sprint-samsung-galaxy-s9-t3783571 which debates whether it will work or not. Also this one specifically about Xfinity https://forum.xda-developers.com/galaxy-s9-plus/help/xfinity-mobile-unlock-service-t3796349. But mine didn't work. I don't think U.S. S9's are cross compatible from CDMA to GSM. I have been searching and searching and can't find a way.
Yes, the US unit hardware is cross compatible. Heck, Verizon itself isn't all CDMA. They are phasing out CDMA soon and most of their network is LTE.
I have a US unlocked S9+ and can use any carrier in the US. You could too, all you need to do is flash the US Unlocked firmware to the device using Odin.
Your problem may be the Xfinity firmware restricting certain bands is all. Or possibly the device isn't really unlocked.

Hey guys when i go to Sony website and look up bootloader unlock instructions. it says the US variant is locked by verizon.
this is the version i have. Does that mean i cannot unlock bootloader? do i need to return my phone and the global version? The guides posted on here don't seem to mention the model number as if it matters.
Unlock Bootloader - Open Devices - Sony Developer World

Unless anything has changed, it is generally known that Verizon phones have a locked bootloader for customer security and in Verizon's interest.

Yea I am a first time sony buyer. the phone i have is actually the 5 IV which we don't have a forum for yet.
I usually am buying older phones with established guides and hacks to unlock on here. So i simply missed this since i didn't see it plastered everywhere on the front page of the some other sony forums. my bad.
I am not surprised. just ordered the wrong one thinking it didn't matter for the sony brand.
returning mine now. and ordering the 72.

It's the same reason I returned US version and bought international version ct72 . So make sure about bands supports for 71 it has 66 which is TMobile and band 41 which i get some good speed depending on the location I'm in.
same here I wanted to root and Use Repainter app and change fonts and I did have the CT62, but I return it back to Sony and bought the CT72, sad that sony doesn`t allow the bootloader to be unlocked on the CT62.

Right i thought they allowed bootloader unlocked on any Xperia really sucks that they didn't allowed it on US specially if I'm paying 1600+ on it lol

my exact thoughts, 1600.00, no thanks, buy the CT72 and save some money, only thing is you don`t get the USA warranty when you buy the Non-US version, and some missing 5G band`s and the missing MMWave bands
As @2015Ducatimulti mentioned, there is something missing there between the two version.
There is Hardware differences between CT72 and CT62. The US version supports has mmW support and also more bands that are available in the US such as band 2, 66, and 71 used by TMO in addition to mmW 260 and 261.
if your carrier does not have use of these bands and mmW frequencies, then the CT72 should still work as long as you flash the US version ROM. otherwise, you will have coverage issues due and high call drops due to the limited US band support

Flashing US ROM on ct72 will give you signal issues. So far i haven't found a way to get signal working on it.
That might make sense since the RF hardware is different between them and hence the software might not work as expected
FWIW, I just got the Xperia 1 IV, CT-72, using it on AT&T (primary subscriber, no MVNO). Just using the stock ROM, didn't flash any other ROMS.
So far I appear to have 5G as well as VoLTE. No VoWIFI, but I don't care about that anyway.
I'll use it for another week or so to see if AT&T decides to shutdown service for a non whitelisted device, but so far so good. And it was $840 new, vs $1600 for the USA version, so a HUGE cost difference
I by the way did first have to do the trick where you disable dual-sim and only use the primary SIM slot.

XQ-CT72 No go on Cricket. Data works fine but no calls.
Does anyone have an authoritative link or source for the different S23 ultra regional model variants and their respective bandwidth frequencies such as for 4g and 5g?
Can't find this information for any including the USA variant eg which specific frequencies of 4g and 5g does the USA model support?
The chipset and x70 modem makes it possible for this phone to truly be a global phone but.....
asking the same as well, cant find these details.
Here's hoping that the band unlock methods for the s22's and s21's also work on the s23's.

I'm sure it will be the same to unlock the bands, no one will really know until they have one in hand.
Can you elaborate on these band unlock methods?
And could they unlock mmwave for example on the international variants so that 5g could work in US? And unlock international bands on US version so it could work everywhere else?

Interesting....
So basically you could enter the service menu and turn on all the extra bands?
In that case wouldn't the US version be the best one to have since it would have mmwave hardware baked in too? It should then work everywhere.
Though it sounds like you'll lose the function on os updates and resets?

OS updates from Samsung are never fast. Doing so once every 2 to 3 months isn't so bad for the extra band support.
Samsung's modem software works well for the US and Canada because the hardware is the same and only the modem software separates the bands based on carrier/region. Due to the wide spread of mess across North America, US and Canadian models are always a good choice for potential band support. In some cases though, mixed ROM's can also bridge the support. In the S9 days, you could.jeep.the base.for.your region but flash the carrier side of the firmware to unlock band 71 on some overseas models. I don't know if this is still possible today but with all devices being very similar. I am hoping the hardware, including dual-SIM pins on the main board, will be there to enable through a firmware change or mod.
Do we know if the international dual sim variant has the same USA hardware based on s22/21/20?
Does it have mmwave baked in but just disabled by software?
I am still not clear what 5G bands are supported on the SM-S918BZKPEUB, nor if unlocking the bands through the service menu works. @UK S23, your deliveries are in place already, has anyone tried?
It seems as though the bands might only be disabled in software? If so, then it should be possible to enable whatever band you need. The only exception would be if a hardware component is needed or missing then it wouldn't be possible which likely wouldn't be the case for your 3g, 4g and 5g standard range. Maybe only 5g mmwave which is essentially only in US anyway.
If that's the case it sounds like US variant might be the best to get for global coverage barring lack of dual sim (though it does have physical+esim).

Samsung's band support is mostly software, at least when it comes to 4G and 5G. I have never bothered to change 2G and 3G bands because there is no use for them unless you are in a very rural area or roaming. This is why it is so easy to convert the North American models and why in the days of the S9+, you could get band 71 on international models with dual-SIM.

Correct me if I'm wrong but you can't get mmwave bands on the international dual sim models right?

I'm not sure when it comes to mmWave. You can enable it on the W for Canada even though the cell coverage and technologies used up there are probably never going to deploy it. Overseas, I have no idea.

I've read that the US and CA models are basically identical so that might explain it. It's also possible I suppose that in s23 since it uses x70 modem, which has native support built in, that all model variants might be able to do it but for software. Though we won't know for sure till someone from different region goes into their service menu and checks.
mmWave requires a specific antenna to function. This antenna used to cost like $50 but I'd be surprised if it's gone down much beyond $30 so manufacturers will still leave it out if it's not necessary.

Thanks and that probably means it likely won't be in other region variants.
Personally, I'd just make a single phone that is globally universal and can be used everywhere. The massive scale should drop the component pricing considerably. Carrier exclusives and market restrictions if any needed in software only. But that's just me lol.

Yes, you would think they would do this, but Samsung has always customized difference models for different regions so it must not be that straightforward. I believe that regulatory bodies would require them to test and submit all the documentation for that extra antenna, for example. It also wouldn't surprise me if the mmWave equipment is outright banned in some regions either for whatever reason.

No. There are 5 different models of iPhone 14 Pro Max, for example, and each will have different band configurations.
That said, the NA models have the most complete bands of any device released so far this year and it was released last year with an older modem. They even have support for Dish Network's n70, a band exclusive to them worldwide, something Samsung didn't even choose to support on their NA variant this year despite having a contract with Dish for radio equipment supporting that band.
I actually think the NA iPhone 14 Pro models support every commercially available band worldwide but I don't really keep up on bands not used in the US.
