Has anyone tried using one of the white unlocked Lumia 920 from Clove (I guess the ones from Expansys are the same) on an LTE network?
Specifically, do you have the "4G" option in the "highest connection speed" settings?
In my case, although I am using an LTE SIM with an LTE network on a supported band, I only have "2G" and "3G" options in the Highest Connection Speed settings. So normally it is only connecting over HSPA. Through playing around a lot with scanning LTE bands with the Field Test tool (##3282#), I can sometimes get the device to connect to LTE, after which it works perfectly on LTE until reboot. But it's not really a long-term solution.
The default firmware on my device is country variant "CV GB SW Variant ID 276 v03" which (apart from the version number) seems to be the same firmware as that sold by Orange / T-Mobile in the UK (i.e. for 3G networks).
I was thinking about trying to flash the EE firmware, but concerned this could create other issues (such as end up locking the phone to EE, or to certain LTE bands, or something...). Any thoughts appreciated.
You don't mention where you are, but that might help respondents.
As you may know, the LTE bands are different between the NA and Europe. The LTE Bands listed on the international version are 800/900/1800/2100/2600 while the NA(Rogers & AT&T) version has 700/850/1700/1900/2100.
Are you sure you are connecting to the LTE bands? Do you have an LTE SIM installed?

Have a look at this offivial Blog post from Nokia.
http://goo.gl/L2eiy
They basically saying that even-thought the new Lumias are LTE ready they will required a software update to turn LTE ON.
The information on that is very limited as Nokia didn't specify ANY details on how they will push this OTA.
What happens if you have an unlock device and use it in a different country of its origins? How they will push the update under what criteria?
Is the update is driven by the SIM ID? They will update the OS and turn ON LTE depending the SIM region or the device IMEI region?? Nobody knows...
Even worst there is a rumor that the latest Snapdragon S4 is supporting all 9 LTE bands at ONCE and the software just enable the appropriate ones, its programmable from the firmware. If this is true, then Nokia is committing a suicide here, they can simply program WP8 to recognize the SIM ID and turn ON/OFF LTE Bands depending the Network. Going with OTAs across different devices and regions will be a mess.

There are international versions that HAVE ALL 9 LTE bands enabled and also petaband 3G.
For example in Germany:
http://www.nokia.com/de-de/produkte/smartphones-und-handys/lumia920/technische-daten/ (expand where it says "Basisdaten")
or in Singapore:
http://www.nokia.com/sg-en/products/phone/lumia920/specifications/ (expand where it says "Hardware")
or also in Switzerland:
http://www.nokia.com/ch-de/produkte/smartphones-und-handys/lumia920/technische-daten/ (expand where it says "Basisdaten")
I think there might be a good chance that you can unlock those extra bands on international versions (RM-821) that have them disabled by flashing a different firmware version. However this is just me thinking out loud so please don't blame me if it doesn't work or if it breaks your phone!
However I would strong discourage you from flashing an RM-821 firmware to an RM-820 (North American version) as I know that sb around here almost broke his phone by doing so.
Hi all
Thanks for your replies so far.
Right now I am using the phone in Japan, where there are three carriers with Band 1 (2100 MHz) LTE networks. I only tried one carrier so far, and yes it is an LTE SIM. As mentioned, I can actually connect to LTE and have used it for several hours, it's just necessary to use an unreliable trick (with ##3282#) to get the phone to see the LTE network. This seems related to the fact there is no 4G option in my highest connection settings.
Thanks for the heads-up on the OTA updates, agreed it's not clear how this will work at all...
Regarding the LTE band support, personally (although it's just my intuition) I think the lists of 9 LTE supported bands on those regional Nokia websites are probably in error (it wouldn't be the first time). Normally the most reliable source in Nokia's website is Nokia Developers, which clearly shows five bands for global RM-821 (1, 3, 7, 8, 20) and four bands for AT&T RM-820 (2, 4, 5, 17).
While the Snapdragon baseband may be able to support all 9 bands, the most difficult part of the design is the RF - filters, amplifiers, etc. So I imagine different RF chains are used in the two variants to support these specific bands.
Again, if anyone has the unlocked RM-821 and tried with an LTE SIM, if you could confirm if the 4G setting is available in highest connection settings, it would be much appreciated.

I thought the same thing on PentaBand 3G and 9 Bands LTE, however in another discussion we verified (at least for the German model) that even thought the Nokia German website states PentaBand 3G and 9 Bands LTE, in the retail Box it only mentions QuadBand 3G (AWS missing) and PentaBand LTE.
With the Canadian model being PentaBand and Snapdragon's S4 Specs claiming that is fully supporting it, along with the programmable LTE, we really have no clue of whats really going on until Nokia, or anyone else clarify it...
I have a very bad feeling that the all 920s are PentaBand 3G and support all bands of LTE with programmable software but Nokia for some reason is locking specific bands on specific models/regions.
Hopefully in time we will clarify everything and hopefully its sooner rather than later..

Different frequency bands require different antenna design. It is probably very difficult to design an antenna that can satisfy all LTE bands even though the chipset can support it. So, instead, Nokia is probably going to selectively make different hardware with different antenna design to fit a specific region. Apple iPhone 5 uses the similar Qualcomm chipset and it only supports very limited LTE bands for international version.

For 3G PentaBand is now standard in almost all chips and since the Canadian variant comes with PentaBand on board and the fact that is standard on the S4 I really see no reason of why Nokia will order a custom version of the S4 to just physically take off the AWS. It doesn't make any sense, so if its missing, most likely is turn off in firmware.
For the LTE. Qualcomm introduced a revolutionary technology called Software Defined Radio or simply SDR and the Snapdragon S4 Plus MSM8960 chip which is inside the Lumia 920, supports that technology. With SDR the chipset support all LTE bands from a low to high frequency, it can work in everything between, of course not at the same time, the software programs what frequency the antenna should be set.
If the Lumia 920 and its S4 really have SDR technology, they it will make sense for Nokia to have the firmware deride what LTE to make available to the user, by reading the SIM region and not providing individual updated per region, or based on device product number.
This finally solves a major issue for the manufactures because they do not have to build customs chips for specific countries, the software simply programs it. If you Google it you can find a lot of info regarding SDR. Of course we are not in the engineering team of the Lumia 920 line and its obvious whatever we say here is based on theory and specs that are available to us.

If you understand radio technology at all, you should know the most important part that make all things work is the radio antenna, not the chipset. The chipset itself can't receive or transmit radio signal without a proper antenna. Try to disconnect your car radio antenna and see how many stations you can receive

We're going a bit off-topic from the thread here, but you're right - SDR defines the baseband, not the RF components.
If you look at Nokia's FCC filing for the RM-821, you can see it has two cellular antennas ("main" and "MIMO") for each of two bands ("HB" high-band and "LB" low-band). Presumably LB is used for bands below 1 GHz or so, while HB is used for bands above. So you can see it's not necessary to have different antennas for every band - bands 1 to 4 (including AWS) could also use the same antennas, for example.
However, each band needs its own RF filters to prevent interference from neighbouring channels, and also needs amplifiers that have flat gain over those bands. These RF components are usually band specific, relatively bulky and expensive, and there are some challenges to use several RF chains in parallel. To my understanding these are the limiting factors that explain why a given device tends to support maximum 4 or 5 LTE channels.

Is that a joke?? I am spending my time explaining what SDR is and I am getting that respond??
I am assuming that I am talking with a person that knows at least a modern chipset like the S4 package contains all the antennas for GSM/WCDMA/LTE a separate antenna for Bluetooth and Wifi, GPS (S4 also includes GLONASS), the CPU and the Adreno GPU.
All the above come in the same tinny chip that in the size of your nail. And all this is called the "chipset". Qualcomm does not use a separate antenna anymore its integrated to the chipset.

With respect, that's not right - the antennas and RF components are external to the chipset.
Go and get the SAR compliance test report for Nokia 920 from the FCC's website, and you can see diagrams showing the external antennas for cellular, WLAN/BT and GPS which are positioned in various places inside the phone's chassis (btw, the LB MIMO antenna is about 7 cm long!)
Or go and check out the iFixit teardown for iPhone 5 and you can see the same kind of thing...

That is correct. Many manufactures are placing antenna extensions and putting additional GPS censor in more practical areas.
The actual GSM/WCDMA/LTE modem WiFi, Bluetooth and GPS for Qualacom solutions are placed inside the chipset.

4g / LTE
tomdjp said:
Has anyone tried using one of the white unlocked Lumia 920 from Clove (I guess the ones from Expansys are the same) on an LTE network?
Specifically, do you have the "4G" option in the "highest connection speed" settings?
In my case, although I am using an LTE SIM with an LTE network on a supported band, I only have "2G" and "3G" options in the Highest Connection Speed settings. So normally it is only connecting over HSPA. Through playing around a lot with scanning LTE bands with the Field Test tool (##3282#), I can sometimes get the device to connect to LTE, after which it works perfectly on LTE until reboot. But it's not really a long-term solution.
The default firmware on my device is country variant "CV GB SW Variant ID 276 v03" which (apart from the version number) seems to be the same firmware as that sold by Orange / T-Mobile in the UK (i.e. for 3G networks).
I was thinking about trying to flash the EE firmware, but concerned this could create other issues (such as end up locking the phone to EE, or to certain LTE bands, or something...). Any thoughts appreciated.

I go into into field test mode and it says 4g then asks what LTE Band. My phone shows 4G not LTE in top left... is it LTE or 3G+?
Does anyone know what the different bands stand for? (band 5 etc) under the field service menu?

Likely they are LTE bands (e.g. band 5 = 850 MHz), but as you probably noticed they don't completely match with the LTE band support of the device. Keep in mind this field test program was probably thrown together by Nokia's R&D guys for internal testing only (not for consumers), so could be a legacy of earlier testing, another device variant, or some other reason...
Anyway, it seems fine to keep this setting on Automatic.

Hi Doug, could you share what version of the Lumia 920 you have, and which firmware?
As mentioned in my mail above, there seems no problem to leave the 4G band on automatic, and the bands available to be selected don't seem relevant. (My device picks up Band 1 LTE networks even though band 1 is not in the list).
Regarding 4G vs LTE, my device (unlocked UK CV) shows 4G in the top left when it is connected to LTE. I assume this can be changed by Nokia depending on the operator's requirement (esp in the US where 4G means HSPA...). You can be sure you're on LTE by going back to the field test menu, selecting GSM option, then looking at "Radio Access Technology". If you're on LTE, it should say LTE there.

I've kept mine on all automatic and i have noticed it switch to 4G at times, but then when i go to use it, it'll flick back to 3G... I'll need to test this in CBD sometime this week.
I got my device from clove, but im in Australia on Telstra 4G network. They use 1800mhz.

Hi, yes better to test in CBD where there's strong LTE signal.
In your Settings => Mobile Network, do you have a "4G" option under "Highest connection speed", or is it 2G and 3G only?
Hi, despite the availability of the International 4g version of the X1 [7d-501L] in italy, that has all the LTE bands that I need, I bought the chinese 4g variant [7D-503L] in order to receive more and quicker updates.
Now, AFAIK the two versions are indentical in hardware, could a developer extract a modem from the international version and make it a flashable zip that we can put on our chinese 4g variants?
This way we could have the chinese 4g version with all the latest ROMs, but still enjoy FDD-LTE in Europe and rest of the world.
Sorry but it is not correct. The international version has a modem with only fdd frequencies, while the chinese version has fdd AND tdd. So, different modem.
You can search this area and you will find at least two others who have tried to do this, unsuccessfully!
I meant that the chinese version has a ton of TDD bands and only 2 FDD bands. Yes the modem is different, but I believe the difference is in software, not in actual hardware.
Hello you can flash 501l firmware on 503l device without any issue, for me. But I think hardware are not the same, 800mhz fdd LTE band is not present on 503l.

I don't need that. I bought 503L to have all the latest rom, it wouldn't make sense to flash an older firmware. Yes 800 mhz is not present on 503L but I *strongly* suspect that it is disabled by software.
I really think that 501L and 503L are the same, the only thing being that Huawei enables certain bands on one, and other bands on the other one.
Yes I understand and it would be great. But when I flash 501l, I should have 501l modem? Maybe it is a hardware switch?

I agree with you that hardware wise, all the different variations of the X1 are identical. Difference is software/firmware based. The difference is located in a partition that is usually not flashed by a ROM update. I successfully did this with my AT&T Samsung Note 2 and unlocked TMo AWS bands with the help of XDA instructions.
To assist you, I came across this website/blog that has instructions on how to unlock FDD bands on 503L. I have not tried it; I live in the US, even unlocking the FDD bands, I will not get LTE (main US LTE Bands are 2,4,17)

Hi. I have a galaxy s8+ which I am thinking of selling to get this phone - mainly because of treble support and the s8+ is too big! I was going to get the 6gb/128gb version which is great value on ali express. I know the Chinese version doesn't have band 20 but that doesn't matter on EE in the UK.
However I wanted to check whether there are other issues with not getting the European version of the honor 9? Does the Chinese version support the new aosp treble based Rom the devs have built? The thread seems vague on this issue. Other there any other issues with the Chinese version?
Appreciate your help.
As far as i'm aware, you can actually re brand the Chinese variant to EU.
Not sure if the version of android on it has Google Play services, or an English language selection, but language packs can be downloaded.
BUT! you will get the OS updates before us lot with EU versions.... who are still stuck on B182, China have got B360 which is oreo.
Either way, its a good buy, destroys the s8 in benchmarks, and just the right size to not be too small or too big in the hand.
There 3 differents STF Chinese honor 9:
AL00
AL10
TL10
I've got an AL00 rebranded to L09 and it's working great, like an European model but without LTE BANDS 7(2600) & 20(800).
Thanks for the responses. I thought the Chinese variants of the honor 9 were the same as Xiaomi - only missing band 20? I'm on EE which doesn't need band 20 but I believe does need 2600mhz (band 7). Any ideas? Thanks
https://m.gsmarena.com/compare.php3?idPhone1=8704&idPhone2=8704#europe,al00
You could change phone version on this link, I think LTE BANDS are corrects but there is errors on size and colors.
Thanks. EE state that most of their 4g coverage is with band 3 so should be Ok! Thanks for the responses guys.
I wouldn't expect huawei to use a different LTE chip in each phone, that would require 2 different versions of the kirin 960, which wouldn't be in the interests of the development cost of the phone.
I'd assume its an OS limitation, since AL10/100 firmwares will run on L09 models after rebranding, and vice-versa.

I'd like it to be true.
Do baseband is inside Kirin 960 cpu chip or in another chip?
The way I see it they ship differents variations with differents nand & ram sizes, so maybe they could switch others things without adding tremendous producing cost.
Or they are the same but phoned still keep their original LTE bands over the publicly available rebranding guides.
I have spent days trying to figure out if I can purchase myself a 1910 or 1913 version of OP 7T Pro, flash it with the 1917 "Global" ROM and have it work with ALL bands in Canada.
According to the OP 7T Pro specs page, there's 2 bands missing: 30 & 71. All the rest are there, and 71 is not terribly important here yet, it will be implemented in the future and is mainly useful for USA roaming on T-mobile.
Now I am aware that there a T-mobile 5G version, I have no interest in this, there is barely any 5G coverage in Canada and in the particular area I live in there is in-fact zero coverage and not expected for quite some time. Also the T-mobile version has it's own separate OS which is seemingly distributed by T-mobile and not OP.
When I check Wikipedia article on OnePlus 7T Pro it lists 3 versions of 7T Pro:
HD1910 (China)
HD1911 (India)
HD1913 (EU) - there's no mention of any HD1917, and the 5G T-mobile version is HD1925.
All previous OnePlus phones including the 7T Standard which uses the same wireless chipset supports the proper bands so I'm sure its something that just needs to be enabled in the ROM configuration.
I'm not sure if there's a method that you can pull up all of the currently enabled bands on your particular phone with an app or a command or checking some file with root?
Does anyone happen to know the full list of bands that are enabled in the HD1917 version of the software (and if so, can you post the command and maybe a screenshot of your enabled bands??)
The other question I have is:
As I understand there is absolutely zero hardware differences between HD1910, HD1911 & HD1913.
Is it purely which version of the ROM that was installed for the region of it's intended market?
Then, on top of that - might there be IMEI issues? IMEI's are usually assigned per region? And do those define what bands are enabled in anyway?
Does it affect anything else such as WiFI regional settings if I have, say, a China HD1910 edition?
And lastly, is HD1917 ROM also flashable on a McLaren edition? Would you lose McLaren "bonuses"?
Thanks guys, hope one of you can shed a bit of light on these for me.

I have spent days trying to figure out if I can purchase myself a 1910 or 1913 version of OP 7T Pro, flash it with the 1917 "Global" ROM and have it work with ALL bands in Canada.
According to the OP 7T Pro specs page, there's 2 bands missing: 30 & 71. All the rest are there, and 71 is not terribly important here yet, it will be implemented in the future and is mainly useful for USA roaming on T-mobile.
Now I am aware that there a T-mobile 5G version, I have no interest in this, there is barely any 5G coverage in Canada and in the particular area I live in there is in-fact zero coverage and not expected for quite some time. Also the T-mobile version has it's own separate OS which is seemingly distributed by T-mobile and not OP.
When I check Wikipedia article on OnePlus 7T Pro it lists 3 versions of 7T Pro:
HD1910 (China)
HD1911 (India)
HD1913 (EU) - there's no mention of any HD1917, and the 5G T-mobile version is HD1925.

Bell is essentially att in Canada right?. I'm using a 1910 on att should work with bell
After rethinking my whole initial post I suppose I'm really only looking for 2 things here. Those being:
1. Can you simply flash HD1917 onto HD1910 (or 1913) model without any issues at all?
2. Does anyone have a list of bands that are enabled in HD1917 version?
I don't mean from Wikipedia or even from OnePlus website but rather an enabled band list directly off the phone itself with a HD1917 ROM installed.
Unfortunately I haven't been able to figure out how to get such a list without using untrusted apps that want access to root.
Does anyone have a clue how to get this list? Maybe it can be read in a system file somewhere?

If any of you are daring enough to try, I came across a root tool, referenced from here:
https://android.stackexchange.com/questions/78974/how-can-i-find-out-which-bands-my-phone-supports
Actual APK download is here:
https://t.me/ru_fieldtest_modemcaps/748
Telegram is required to download the APK, here are instructions pages (translate to English if you don't speak Russian)
https://telegra.ph/ru-fieldtest-modemcaps-intro-03-26
https://telegra.ph/ru-fieldtest-modemcaps-faq-03-26
Anyway, if you have root and grant this access, it will report all bands that your current phone build supports.
I'm really looking specifically for HD1917 builds, we already know what the other builds support purely from OnePlus specs page & Wikipedia. I mainly wish to know if this "Global" version of this ROM adds any extra bands for North America.
Really appreciate anyone who does this for me. Thanks!
I'm back again! I believe I discovered a way to list supported/enabled bands without root now as well if anyone would like to try and report back (please include your specific actual model number as well, HD1910, 1911, 1913 or whatever you have).
Simply install this app (which only requires a single permission, install shortcuts):
https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher
- Once that's installed, load it up and scroll way down to "RFToolkit".
- Click it to expand it, then long press/hold on "Band[][]" (the two squares are some Asian letters).
- Hit "Create shortcut". It will add it to your home screen.
- Then from your home Screen simply launch Band[][] and it should list enabled & disabled bands on your OS.
If nothing is checked you can try "Reset to default" and it should check all the normally enabled ones.
Sometimes you also have to launch the app a few times for it to properly list bands (at least I have had to). Closing all background apps sometimes helps with this it seems.

As to toolhas4degrees, sorry for not responding to you earlier.
Here are the Canadian bands that should be supported:
Bell ---- 2/4/5/7/12/17/29/30/40/66
Rogers -- 2/4/5/7/12/17/66
Telus --- 2/4/5/7/12/17/29/30/40/66
Freedom - 4/66/71
I don't believe any edition of the 7T Pro supports 30 on any firmware version (but the chipset does support it if we can find a way to enable it, with that said, 30 is barely used and may even be entirely discontinued so it's not a big deal) - interestingly though, the 7 Pro also doesn't support 40, yet the 6T supports both :-/
As to AT&T, here's the list of U.S. carrier bands:
AT&T ----- 2/4/5/12/17/29/66
T-Mobile - 2/4/5/12/46/48/66/71
Verizon -- 2/4/5/13/46/48/66
So yes, you are right, AT&T & Bell/Telus use very similar, pretty much identical bands.

Well if you use bell or Telus the 1910 would work fine. IDK about 5g bs etc, bc it is so minimal it won't be prevalent for 3 to 5 years
Hey,
I'm not sure if to create a new post for this. but:
I'm a bit confused I have OnePlus 7t Pro Mclaren Edition - but it states it is HD1913 and not HD1925.
We just got 5G in my country and I think that HD1913 doesn't support it in a hardware level.
Any ideas?

I am from Quebec, city and I have the Chinese version HD1910 for a few months already and everything is really functional, no difference with the other that I had the HD1913, I am on the Telus network and no loss or drop in signal.

When I was looking for my 7t pro on eBay. I'm pretty sure I saw a 4G model of the McLaren that wasn't T-Mobile branded. Maybe check GSMArena or something like that for the specs of that model number. I think I just googled the 7t pro model number list.
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?

This is the thread you probably want to have a look at. This method also worked for the s21's.
How to Enable All Bands Through Service Menu on US/CA S22 series (including Sub-6 and mmWave)
What is this? This is a guide on how to enable all LTE and 5G bands on the US or Canadian S22 series phones by going through the service menu. This guide is mostly based on this S20U guide by mellojosh, but has been adapted for the S22U phone...

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.

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.
