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.

I saw a couple of tech points in the other threads. I myself have purchased the Att variant and planning to set it up with T Mobile but as I said, someone pointed out that they have different cellular banding or something to that effect. This person went on to say even if we were to get the ATT Gear S version on T Mobile that speeds would probably only be 2G.
From the articles that I've read on the Gear S specs I haven't come across anything saying that Samsung has designed specific versions for each U.S. carrier.
I do not have the answer at this time whether or not full cross compatibility is built into the device or not. Purely going by what has been announced, again I do not think it has been modified to keep us from doing carrier jumps.
I will update when Tmobile gets their networks up and running for the Gear S. If anyone can clear this up with for sure information, please do so. Feel free to speculate but if you're not certain please say so. Thanks.
If I can't get full functionality on the TMobile network with my ATT purchased and unlocked Gear S, I guess I'll have to return it and pony up the extra $50 that TMobile charges and fully join that club. Guys it may not be worth the hassle. I'll have an update soon on how all this works out, however I'd like to welcome feedback on the issue.

Im doing the same thing tomorrow.
You can go to Samsung.com to check out the official spec. There are 5 different carrier variants but only three listed so far: AT&T (SM-R750A), Verizon (SM-R750V) and Sprint (SM-R750P). The missing two are T-Mobile (SM-R750T) and US Cellular.
Each listed different supported network (CMDA vs GSM) and bands.
It has the Snapdragon 400 which supports a HUGE number of bands and supports a global mode for both CDMA and GSM.
https://www.qualcomm.com/products/snapdragon/processors/400
https://www.qualcomm.com/products/snapdragon/wearables/samsung-gear-s
Someone will figure out a way to get the device to work with them back and forth ... it may be through a rom or a command line. But if you aren't a tinkerer you'll probably want to go with the version of the watch for your preferred carrier.
Update: I did a search through the FCC and didn't see one with T-Mobile specific bands (1700/2100). Bad news though is that there definitely are two variants for CDMA AND GSM. Argh. I stand brutally corrected!
Is the US version of the Z5 compact separate hardware? Or is it the e5823 with custom software for the US that has full Tmo support?

What do you mean by "full Tmo support?" Do you mean VoLTE and WiFi calling? Unless it's a T-Mobile branded phone it will probably not support those things. I've had several unlocked Android phones on T-Mo and they did not have those features (including my Z3 Compact and Z5 Compact). The only one that comes close is the iPhone which does have WiFi calling on T-Mobile when using the unlocked version (because, I assume, they have no branding anyway).
We must have made our threads very close. I was asking the same thing. On one hand, the US version doesn't have the fingerprint scanner but may have better radios for the US carriers.. On the other hand if the international version has the same radios, it's also cheaper. Not sure what to do as I don't seem to have a clear answer.

This is not accurate. Nexus 5x, 6p, HTC One A9 all have proper T-Mo support including Band 12, VoLTE, HD Voice and WiFi Calling and are unlocked/unbranded. Pretty sure Moto X does too.

OK. I had a Nexus 5X and I don't remember support for WiFi calling, but I only had it for two days. My Sony devices don't support it.
I guess the correct answer is it depends on the device.

According to Amazon site for Z5 Compact "Fingerprint sensor is not supported." (see last line of specs under "From the Manufacturer.") Read: It's there, but without software support.
This leads me to believe that hardware is identical to E5803 or E5823 and only fingerprint sensor software/drivers are not included in US customization.
That makes more sense than Sony building a completely different model for the US market that they would have to support with different parts, etc.
Also means that someone with a US variant should try flashing a non-US customization and see if the sensor 'awakens.'

Yes, that probably would work. You can get it more easily buying one from Clove UK with the sensor software already functional.
Granted you'd have to return it to Clove for warranty support but I wonder how a US distributor would handle warranty support on a phone with a different customization. I suppose you could put the US version back on it for support.
Looks like the bands are better for US carriers including the infamous band 12 for Tmobile. Think I'll go this route since I'm on Tmobile

I'm using an Asian model and get a band 12 signal on T-Mobile according to LTE Discovery
I ordered mine from amazon, and am using on T-Mobile, it does have fingerprint sensor. Pretty sure there is one model that supports pretty much every band there is. US model is the same except the fingerprint sensor as I read in the news, not sure how I can tell mine is US model as it is not indicated anywhere.
Ever since I got out of my contract and started using prepaid I never bought a single phone from a carrier. ****ty logos, apps and sometimes software, and apparently now different hardware? No thanks..

nope, no VoLTE on mines.
I have tried other forums and I am getting conflicting information.
I am looking for an Android smartphone that is capable of dual SIMs. I know that Apple iPhones can
do this, but I want an Android.
Some places I have read that the software on some smartphones designated for the United States
market have that feature disabled.
Anyway, my ideal smartphone would be:
Dual SIM (one physical and one e-SIM is acceptable)
Will work on AT&T and Verizon Wireless MVNO (like Total Wireless)
Has 5G bands for both AT&T and Verizon.
Will do wifi calling and texting, natively, on AT&T.
I think a Google Pixel 6 would do this. What I can't determine, yet, is if I should just buy the
unlocked Google Pixel 6 or the AT&T version. The unlocked version is $599 and the AT&T version
costs $739. What do I get for the additional $140?
pixel 6 is not dual sim, atleast not one the unlock version...
The $740 model has mmWave support. The base version does not. If you want to use Verizon and AT&T's fastest 5G, you want that antenna. Just beware that 5G is in extremely limited areas currently and mostly only works outdoors too because it doesn't have much building penetration capability. I personally would save the $140 since Verizon and AT&T are in the process of rolling out C-band 5G which IS supported by the modem and has much better range and building penetration.

Slight tangent, but do you know if there's a way to check which version I have? I got mine as a refurb off Amazon, but it's unclear whether I got the GB7N6 or G9S9B (to my understanding the G9S9B has mmWave?) - and I swear I saw "G9S9B" in some device-info app but I can't find it again.
Edit: Oop, solved my own question. Termux getprop ro.boot.hardware.sku -> G9S9B. Neato. ...Don't know how that happened because I thought the G9S9B only came from AT&T and Verizon and I got it pre-unlocked, but I'm not complaining.

most of the things should work
I did look on this specs first, after I got it seems like there is something additional. There is one spot I get a super connection but 90% of the time weak or no Service at all.

Asia version without mentioning it
go to settings and all the way down you should see your model number. Considering that USA specific is not out yet you most likely have asian one which is XQ-CT72. EU one is CT54.
But those should work on t-mobile network, most of the bands are there. And those are low bands, so longer range.
It runs at limited feature support. Sony disables VoWIfi for US models and many other features including Bluetooth features such as Bluetooth meta data.
Sony blames T-Mobile for limited feature set. you will need to root your phone to hack up the build to enable VoWifi and other features.
This feud between Sony and T-Mobile has been going on for the past 10 years and Sony still playing ignorant to US market.
if you don't care about such limited feature set, Xperia 1 IV should still work on TMO
I just got my phone yesterday and realized the same thing happened to me, I didn't have service where I used to but I managed to get it working by: going to settings, then network and internet, then Sims, scroll down to access point names. And two options should pop up, I changed mine to T-mobile US LTE.. And restart, which worked for me.

Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file

I have been using the XQ-CT72 here in michigan on GoogleFi, which is basically t-mobile, in my town where I live, I get 5G without doing anything to the phone, but with that said, I work 20 miles out in rural area and apparently from my research tmobile use band 71 for 5G in rural areas, I can get LTE+ but no 5g at work, my Pixel 6 pro can get 5g but its like 1 to 2 bars that`s it, but with my sony I get full bars of better signal on LTE+ with my Sony, since the Sony is missing the n71 band for 5G, but I`m fine with what I get, since at work I` m on wifi anyways, I`m happy with my purchase, I originally had the US model on pre-order and the release date was pushed back to Sept. 22-23, so I cancelled my pre-order and bought a new one on ebay for 1069.00 compared to sony wanted 1599.00 for US mode
EDIT: I ended up send it back to seller, the 5g icon was not really 5g, if you're in the USA I would wait and buy the USA version, which I pre-ordered from Sony website, expected ship date is 22-23
moving to GoogleFI is the best option to use this phone in the USA. it will utilize Tmobile USA and have all feature enables.

Only way to know for sure it to just buy it and try it for your usecases. Just buy it somewhere with a good return policy. I bought mine on Ebay with a 30-day return policy and so far it works fine on AT&T. Just make sure you do the trick where you disable dual-sim. (Google the details, it's somewhere here on XDA or on Reddit).
I bought my USA variant phone a week ago, and everything on T-Mobile works with the exception of Wi-Fi calling. The only alternative we have is to stop using T-Mobile and switch over to Google fi which does support Wi-Fi calling. Other than that my phone is flying super smooth and with fast performance like I've never believed compared to my old LG v30 Plus. I'm definitely impressed with this phone.

From a technical point of view, the phone should work on all carriers in the USA without issues, (with the exception of the Sony/T-Mobile Wi-Fi Calling issue that forces those who want Wi-Fi calling to switch to Google Fi, Mint Mobile, and other MVNOs).
Whatever service is in the area should work. Verizon will provision your phone to work with it's network. CDMA based carriers are supported per Sony's phone settings, so I would just go for it.
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).

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.

Yeah.
Are iphones globally all exactly the same now?

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.
