Hi guys, I would like to buy the S20 Ultra version in China from Samsung Store, to get the Snapdragon, but will be the Chinese ROM on it. Do you know if is possible to request to Samsung to have the Global ROM version? Or to install it at the moment of the purchase? Otherwise how can I solve this problem? Will be easy to do it by myself? Since is a expensive smartphone I don't want make any mistake..
Thanks for your help!!

Likely not. Hong Kong should get the SnapDragon. The Global model should be Exynos. Can't interchange the ROMs for it. Needs to be confirmed, but likely The snap dragon will behave better RF and battery wise. Maybe not a huge difference as with some older chipsets, but something to keep in mind. While Hong Kong may not get the OTA updates as frequently, you get a dual sim SnapDragon model.
hope this helps.

The Ultra international version is likely SM-G988F/DS, where the SnapDragon Hong Kong/Taipei version could be SM-G9880/DS.

The chinese versions typically have wireless bands that aren't supported in the US so I wouldn't use that. However, the Korean Version *will* use the snapdragons this year, and should be completely unlocked. Those should be fully compatible. I bought a Korean Note 8 because that was the only one which came in 256gb and the rare blue color and I've had no issues. It was Exynos, though. I'm hoping a lot of people in the developer community will buy this unlocked snapdragon version but I may not be so lucky. I might be forced to purchase the european "global" version.
Perfect!! Thanks, I will buy it in South Korea. Unfortunately they did it in only 2 colours this time...

Not sure which spec sheet you have seen. The SM-G9880 from Hong Kong should cover all the North American bands. AWS may be missing, I see it on some lists and not on others. I would be surprised if the Korean N version is better than a global F or Hong Kong’s 9880 version. I expect the 9880 to be similar to the U version but in dual sim format.

Yeah, I could be mistaken. My hope is just that with the Korean version also using snapdragon this year, people will be more open to buying that version over the International F. Development should be much easier and last longer with a snapdragon.

I hear you. I wish the Exynos was better, we’ll see what this new SoC will do, but the biggest hurdle as I understand it, it’s licensing and regulatory. I’m sure SAMSUNG would prefer to make a single version for the globe and just apply CSCs for customizing. To me, carrier and market demands are crazy. Single va dual sim, price, customizations, band support and features. If you put dual sim for everyone, a region will ask for a cheaper single sim. There’s no way around it, it’s insane.

Here’s the official band list from the Samsung China e-store. The 5G bands listed are more limited than what the Techwalls site says for GM-9880 (doesn’t support the US 5G bands listed there). The 5G bands listed are the same as the China Note 10+ 5G version, so it might be right. I was hoping it supported all the same US model 5G bands, but not sure now. If anyone has an actual G9880, sharing the real bands via an app would be great.

I think one of these apps will give you information of which 5G bands you are connected to. I thought there was an app where u could select different bands and force it, but maybe not or it has to be done manually. It looks like you are on T-mobile, so maybe you could try different areas/towers and different bands to test. On the Play store, there are also a few other 5G apps with maps of the different towers that can help you get close to test the high or low 5G bands. Thanks for your contribution. I’m really curious if both the high bands and low bands for T-mobile are supported on the 9880.

As for the moment on my 9880, i don't have 5G because "apparently" HongKong and Taiwan don't have 5G yet, thus it will be coming in a future firmware update. I tried to flash via ODIN the HK firmware but i got the BRI (Taiwan) CSC back again...

But so check this, I have my 9880 and my girls 9810, both rooted unlocked etc.
She's on ATT i'm on T-MO
Neither of us are getting carrier aggregation. a S8 on t-mo got 102mbps and i got 34mbps in the same spot.

Do you want the following information?
I live in Taiwan, the phone model is SM-G9800
Taiwan ’s current telecom operators have not yet provided 5G services
If you need to provide other information, I will try my best to assist you
same issue here... got TGY on my 9800, i live in Switzerland and should get 5g or even 5g+ but nothing... i guess it's a frequency issue.
Now my question is : can we change the frequencies of the 5g on the phone?
Would anyone know if the sm-g9880 snapdragon model the 256gb 5g would work in Australia ? I think we use band 78? I can't find any details anywhere.

How are you able to get that? What app is that ?
My model is the sm-g9880 Taiwan firmware.
I tried to download the hongkong firmware but it didn't change the CSC for some reason. I did a full reset.
I thought maybe it's the firmware that's not approved for 5g yet because apparently Taiwan hasn't activated 5g yet.

Its called Quick Shortcut maker.
My G9880 was originally csc BRI but I have changed the csc to TGY using Samkey as 5G hasn't been activated on the BRI model yet but was activated on the last update for TGY.
I have the Samsung Factory Unlocked version of the S20+ (model SG-M986U1).* This means the phone is not carrier-specific, it works on all carriers (CDMA, GSM) and supports both millimeter wave (Verizon 5G Ultra Wide UW) AND lower frequency band 5G (usually called Sub 6).* The 5G UW super fast network is typically only available in highly populated areas (cities) because it that frequency signal doesn't travel very far and is easily blocked by buildings.* However you will notce the Verizon 5G coverage map shows 5G as being pretty widespread across the country.* Most of that is their Sub 6 5G Network which was launched in mid October 2020.* The 5G Sub 6 network, to my understanding, is using some of the same frequency bands as 4G so essentially it's really an amped up 4G signal using what is called Dynamic Signal Sharing (DSS)*(A lot of people don't understand all this.)*
I'm curious if there's anyone on the forums with a factory unlocked version of the S20 (typically the model number I think has a U at the end instead of VZW) can confirm if their phone shows a 5G icon when you are in sub 6 5G or does it show "LTE+"* I read somewhere the unlocked phones show LTE+ because technically that is what Sub 6 band 5G using DSS really is and 5G in that case is more of a marketing term.* Because different carriers use different terms for different networks, the factory unlocked phones can connect to all the different 5G networks but they can't accomodate all the different marketing terms.* I'd also be curious if when connected to the millimeter wave 5G in the cities if these factory unlocked phones show the "UW" designation which is bascially a Verizon marketing term, or if the phone just shows "5G".
There was also an article that talked about these phones needing a software update to use 5G and supposedly the updates were pushed out right after Verizon announced their Sub 6 5G network launch in mid October. But the author wasn't sure if the Factory Unlocked non-carrier specific models would receive the necessary update. Considering Verizon and Samsung just signed a 6.5 Billion Dollar agreement for SAMSUNG to further build out their 5G network, I would be very surprised if it were the case the factory unlocked models didn't get the update.
My S20+ model SG-M986U1 is showing Service Provider SW Ver. SAOMC_SM-G986U1_OYN-VZQ_QQ_0027 wondering if that's the 5G compatible version?
The other thing is a lot of people just swap SIM cards when they get a new phone. With 5G in most cases, if your SIM card was issued may months ago, you need to go into the carrier store and have them give you a new 5G compatible SIM card. I honestly can't remember if my phone was showing LTE or LTE+ before and after SIM card change. I tested the bandwidth after the change and in a strong signal area got 60mbit download but I didn't have a pre-SIM swap test in that area to compare to unfortunately.
Well I feel like I'm going in circles but now found a Reddit thread that confirms what I originally suspected.
The Factory Unlocked (model ending in U1) S20 phones apparently have not got the update from Samsung yet to allow sub 6 5G connection. But there is a hack in that you can change the carrier network code to ATT even though you are on Verizon and it enabled the N5 band which is what Verizon uses for their "Nationwide 5G" To do this you dial *#272*your IMEI number# Then select ATT and Install and change network code only. Phone will reboot and now you will see 5G UW symbol.
I tried the CSC change on my factory unlocked S20+. I ran three successive bandwidth tests on bandwidthplace.com before and after the change so 3 times on VZW and 3 times on ATT. As others have alluded to the LTE DSS Sub 6 Flavor of Verizon 5G is on average about the same speed as 4G LTE+. So I just turned it back to VZW and will wait for the update from Samsung. I'm surprised a month and a half later it still hasn't got the update to allow N5 band on Verizon.
I'm also wondering is the S20 always show 5G UW when connected to any 5G including sub 6 5G and not actual millimeter wave ultra wide 5G? Or is that just a side effect of "spoofing" the ATT carrier code when actually on a Verizon network IMEI?
Hello Jazee, this is my first response to anyone on xda, and I know that by now you probably have your answer I notice this is an old post. I have an unlocked Samsung s20 5g. And depending on where I am, it says 4g let, and when I'm closer to the city, or hold my leg right(I live in the country), my phone shows 5g. It's shown lte+ before. I think it depends on your carrier. Some I've noticed share 4 and 5g lte simultaneously depending on the current speed. As you mentioned earlier, 5g signal doesn't put up a big fight when it sees a tree or building. Anyways, that's my 2 bits worth, hope this helped. BTW, lte+, when I get that, it is pitiful. Nothing like either 4g lte or 5g lte.
Do you know if there are physical differences between the two or if it's just a firmware difference?

mmWave requires a dedicated antenna, in place of that there is just a useless piece of plastic in the Sub-6 only versions (just watch a couple teardown videos, they'll notice/explain that).

That's exactly what I was looking for, thanks!
Any ideea if there is a software difference between GLUOG and G8VOU ?
Looking to get G8VOU to use with Bell Canada.
I travel across borser a lot.
I currently have a Note 20 Ultra 5G "U1" version, from US and Bell Canada won't recognize the TAC and cannot get 5G in Canada or register with ATT or Verizon since no IMS registration allowed by Bell Canada because of the XAA CSC. So basically can't use it with Canadian Carriers. No options to flash it with a "W" firmware either. Thank you Samsung.
Looking to leave Samsung and get a Pixel 6 pro but wanted the G8VOU for 260 261 band.
Any thoughts, will the G8VOU will work with Canadian carriers ?

There are no software differences, both variants run the same firmware.
You're gonna be between a rock and a hard place though.
The rock is that you can use the G8V0U on Bell however you might only get 3G.
I checked the IMEI for a Pixel 6 and it said it would be Sub-6 compatible. I checked the IMEI for a Pixel XL and it said it would be LTE compatible. However, when checking with an IMEI for a G8V0U it only said HSPA compatible, nothing about LTE or Sub-6.
No guarantees about LTE support, which by extension means no guarantees about IMS, even if Bell doesn't have whitelists.
The hard place is that if you were to instead get a GLU0G for Sub-6 and IMS support in Canada you'd be on the reverse end of the stick in the US as both AT&T and Verizon operate whitelists.
AT&T only allows the G8V0U for IMS, and because AT&T is an IMS only network now there is no way to use the GLU0G.
Verizon is still running their CDMA network but it doesn't matter because their entire network is whitelisted and they don't allow the GLU0G.
Your best bet if you want a Pixel is to get a Pixel 6 GB7N6 which can be bought unlocked from the Google Store and will work on all networks in the US and Canada although it only has Sub-6 and not mmWave.

For which hardware?
GLU0G roaming in the US should be supported according to Bell with LTE/VoLTE/Sub-6.
G8V0U roaming in the US will not work because you need IMS, and Bell doesn't provide that with the G8V0U.

Ok, that is what I was afraid of. I appreciate your reply. I guess no matter if it's Samsung or Google, it has to be a Canadian version in order to avoid all the hassle I am putting up with now.
I am in US now, using Note 20 5G U1, and can only register on Tmobile for voice and get only 3G. ATT will let me register but only getting LTE data and text but cannot place or recieve calls.
Verizon, lets me register for a few seconds then kicks me out.
I was looking for an answer about what device to buy and I was hoping Google's story was going to be different but from what you've described, I see no difference between them.
Bell support was "0" since not a device that they sold.
So I guess I'll have to chose between S22 W and GLU0G.

iPhones have different variants for countries that haven't certified mmWave or have other frequency restrictions but Apple mandates that carriers support all variants that have basic support for their frequencies.
USA variant iPhones have mmWave that can't be used in Canada. 100% band support on Bell and might miss a single band on others but still work completely fine in Canada.
Canada/Japan variant iPhones don't have mmWave, will 100% work in Canada, have all bands for AT&T and Verizon, except the 11/12 miss a single band on T-Mobile but will still have service.
Both variants will roam in any combination, but a USA variant won't gain mmWave when roaming in the US as Bell doesn't have mmWave roaming contracts with carriers.
