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.

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

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).

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?
Had made the same thread in the S8+ forums when I had that phone, however I upgraded to the N8 and have made the same thread here since it helped a lot of people in the S8 forum.

Why starting this thread, while the OXM-info is already here:
https://forum.xda-developers.com/showpost.php?p=73879369&postcount=3
Your document could also be implemented in that message (you just had to ask!)...

The document I linked shows what each CSC actually stands for.
You can link it in the first post if you want.

This is brilliant. Thanks! Have been trying to find a complete, intelligible list for a few days now. Should have started at XDA of course ...
Small correction: XEH stands for Hungarian unlocked only, Vodafone, Telenor and T-Mobile all have their own CSC codes (VDH, PAN and TMH, respectively - PAN because Telenor used to be Pannon GSM Hungary).
Am i correct that in the US, the carrier variants and even the unlocked version are all identical hardware with the same bands supported and it's just the software is different?

Yes you are correct.
There's a carrier switching guide in the forums as well.

Yeah, I saw the carrier switching guide. I was just confused as someone mentioned that the hardware was all the same so the band support is the same except the carrier might have their own bloatware but the page below seems to indicate that the unlocked US and US Carriers is different when it came to band support. Can I get the Verizon version and have all the bands enabled or do I have to get the unlocked US version?

Thanks, just wanted to make sure that I get the right one so when I travel outside the U.S., it will support everything. Am I correct that the only difference might be some may have bootloaders that won't be unlocked while others might when it came to carrier variants?

Well actually, Samsung locked everyone out so it doesn't really matter which variant you have, both the N950U (carrier variants) and N950U1 (unlocked variants) have locked bootloaders.
All of them should work fine outside the US when roaming, wouldn't really recommend it if you live outside the US though.
Yeah, I meant I thought some bootloaders would become unlocked later, I just know the Verizon one never seems to get unlocked compared to T-Mobile for example even with other brands of phones. If I had a choice, I would get the 128GB model which is available outside the U.S. except I don't know if it supports all the U.S. bands. Just wished Samsung was like Apple when it came to band support like the unlocked SIM free which seems to have support for all bands except for Japan when it came to 4G LTE as without the proper support, it will roam but be in 3G for data instead of 4G. With that said, just looked at the chart you provided and it seems like the SM-N9500 would be ideal for the 128GB or 256GB internal storage except it is missing the following bands which is on the US models:
3G (UMTS/HSPA): 1700
4G (LTE): B13, B17, B18, B29, B30, B66, B252, B255
So it seems it is actually the US model that has more band support while the China model has more internal storage.

That is correct. Chinese variant and Korean variants have the most storage options while the rest of the world is left with 64GB only.

I'm interested in the S9+, but I live in the United States and I'm afraid the locked bootloader of G965U will leave me with a very expensive dinosaur in a few years when Samsung official updates cease. Mainly for that reason (also because I like to play around with custom ROMs and would like the option of 128GB internal storage), I'm considering purchasing either the G9650 or the G965F variants. I've read that the G9650 has little to no developer activity, and I like the terms/price offered by clove.co.uk/samsung-galaxy-s9-plus, so I would probably lean towards G965F.
What I'm having trouble determining is whether either G965F or G9650 will definitely work with all of my carrier's (AT&T) 3G and 4G bands. From forums.att.com/t5/Phone-Device-Upgrades/What-are-AT-amp-T-s-4G-LTE-bands/td-p/4067288 and gsmarena.com/samsung_galaxy_s9+-8967.php#g965f it seems like the 4G bands AT&T uses should theoretically be supported, but I would prefer anecdotal evidence to theory. Has anyone confirmed that G965F and/or G9650 work at full speed with AT&T's network (specifically 4G)?
Yep, it'll work. Canadians typically roam on AT&T while visiting 'murica because we no longer have a cdma carrier like Verizon/Sprint. I'm using G965F fine on Canadian networks.
But here's a site for you too.

What kind of download/upload speeds do you typically see? I'm a little concerned about the lack of B30 support as I'm in the NYC tri-state area and the network can be pretty congested.

I haven't noticed any speed issues, but I haven't been to your area so I can't really compare.
You can check out https://www.cellmapper.net/ and see what AT&T bands are most commonly deployed in your area(s) and make judgment call
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
developer.sony.com
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.

Does anyone have this variant running on verizon? If so how does it work?
You can always check the bands that model supports vs the bands for Verizon in the area you plan on using it. Both sets of information are available online. Cell mapper I believe is the app you see what bands and networks are in your area and GSMArena should have the bands listed for that model.
I have looked and 4g has all the bands 5g is missing the mmv ones but can't find anything on 3g for either one.

I looked it up and yeah the only models that support us 5g mmw is U/U1 models so no 5g and likely 3g isn't supported on models that are outside us is my guess.
