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.

Has anyone found the network specs for this model?
I need the LTE and 5G band list.

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.

can you check the following please :

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.

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.
Hi,
As for 4g phones, 5G One can be used in Europe, and in details in Italy. For 4g Chinese phone missed band 20, what is for 5g?
Thanks
I am checking that for germany right now, i see some missing. More than i have expected.
Germany will use the old UMTS frequencies in Germany for 4G / 5G.
So i am missing for 4G b8, b20, b28, b32 and for 5G n1, n28.
10min search, may be missing some.
Italy
Italy using for 4G/5G (wikipedia)
b1,b3,b7,b8,b20,b32, n78, n258
K30 Provides (chinese Website translation)
n41, n78
b1,b3,b5,b7,b8,b34,b38,b39,b40,b41

Ciao, hai poi risolto? ANch'io l'ho comprato di recente.
It's fake that you can unlock the LTE missing bands: it's a hardware limitation.
I am using the K30 5G in Spain and it works pretty good, I almost see no difference with mobile data with my previous phone, the LG G4, and besides I am prepared to receive 5G signals in my city
If you guys finally decide to buy this phone, buy the K30 5G variants, as it also has some more 4G bands than the normal K30 4G variant.
In Spain we use B1, B3, B7, B8 and B20 4G bands, and picasso only misses the B20 band.
is there a variant that i can root and use on tmobile 5g?
Forget about trying to root Snapdragon versions.
@42o247 forget @roaduardo and his wrong answer.
if you want to root Snapdragon get SM-G9860 for S20+ works like a charm.

i tried that before i even posted but most of the results are for the sm-g9860u and from the how to root guide it seemed like all the variants ending with U were unable to unlock the bootloader or root. i figured i would ask if anyone had a personal opinion or knowledge before wasting more of my time searching. thanks for the response though your thoughts are sincerely appreciated.

These are T-mobile's 5G Bands.
Band n71 (600 MHz)
Band N260 (39 GHz)
Band N261 (28 GHz)
Band n41 (2.5 GHz)
These are the SM-G9880 and SM-G9860 5G Bands.
Bands Sub6
Band N41 (2.5 GHz)
Band N78 (3.5 GHz)
Band N79 (4.5 GHz)
Samsung S20 5G UW Bands
260, 261 mmWave
The device "should work" on Band N41. Also, keep in mind there are different variants of 5G Protocol. Low-Band, Mid-Band and Millimeter Wave. mmWave is the gold standard when speed is the only criteria.
mmWave high-band 5G: T-Mobile, AT&T and Verizon. About 10x faster than LTE with extremely low latency, which means you need to be standing really close to a tower or transmitter to get those speeds. Mid-band 5G: Sprint. About 6x faster than LTE, but with a smaller footprint than low-band. Low-band 5G: T-Mobile/AT&T. About 20 percent faster than 4G LTE.
If I were compelled to utilize 5G, which at this time I'm not, I would consider AT&T. They are the only Service Provider offering mmWave 5G on a Samsung 5G UW Device. Even though it has a Snapdragon SoC, I suspect the bootloader is locked like all of the US Carrier Devices.

yeah you should pass on Samsung in general and get a 8 Pro. But if your decision depends only on 5G I have to say it shouldn't be that important, because 5G isn't that relevant so far, and maybe for the coming 1-2 years. And I'm sure won't keep the device longer then that anyways...
Also 5G caused CORONA VIRUS!!! LOL just kidding,

Even device support n41 ( 2.5 GHz) that doesn't mean it work in T-Mobile/Sprint 5G-network because it require anchor band on 4G. But i don't know much about this Hong Kong variant because haven't got any log from it. If someone have, please share. Here is instruction to get modem log: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Please send log to: https://cacombos.com/contribute
I have some S20 variants supported bands and these combinations in my site: https://cacombos.com/search?key=S20 . I just need more data from these devices to complete listing.
But in USA i recommend buy device in US. Devices from overseas doesn't often support 4G and 5G carrier combinations used in US so you get less speed on network.

A great resource and good to know, thanks! I agree with your suggestion to purchase the device from your Service Provider, that will pretty much guarantee you'll have all Carrier Aggregation utilities and 5G Connectivity Protocols in place. Unfortunately, users want a phone which has everything, no bloatware, unlocked bootloader, universal connectivity, full carrier aggregation and the best SoC. With all the variants from Samsung and varied Service Provider metrics that's not realistic.
I have a few questions you may be qualified to answer. Does the first letter of a band being capitalized or not have significance? Example n71 or N71? Does this represent MHz versus GHz? Secondly, in the example above, both the device and AT&T have a number of matching 4G Bands. Would this indicate the device will be able to anchor to the carrier? Lastly, let's assume a device and the carrier have multiple matching bands. Who or what determines which band will be paired in a specific connection, will the carrier determine this based on location or traffic volume, does the user have the ability switch to a specific bandwidth?

A great resource and good to know, thanks! I agree with your suggestion to purchase the device from your Service Provider, that will pretty much guarantee you'll have all Carrier Aggregation utilities and 5G Connectivity Protocols in place. Unfortunately, users want a phone which has everything, no bloatware, unlocked bootloader, universal connectivity, full carrier aggregation and the best SoC. With all the variants from Samsung and varied Service Provider metrics that's not realistic.

n71 and N71 is same band 600 MHz 5G NR. But in cacombos.com you see different characters like C what means contiguous intra-band CA. Example 3C.
On cacombos.com you can see example combination 2A4-66A4A_n71A2A what means 2-66_71 CA combination. Band 66 is anchor band for n71 5G.
Samsung technical expert on chat said yes,
the modem the phone has seems to indicate it does (unless samsung disable something on the S20 5G specifically to limit it to Sub6 bands only),
https://www.samsung.com/semiconductor/minisite/exynos/products/modemrf/exynos-modem-5123/
this webite seems to say no (no mmWave bands listed),
https://www.devicespecifications.com/en/model/f3e652f5
to add to my confusion the verison S20 5G originally didn't support mmWave until they released the S20 5G UW
I'm in the UK on EE. I just would like to know if the phone can or can't receive mmWave if it was transmitted to it?

I think you're out of luck if you didn't purchase the 5G UW. There is no modem technology currently available that can leverage 5G signals in the sub-6 GHz spectrum and 5G signals in the mmWave spectrum at the same time. You can only get one or the other.

Not so, Verizon released 5G mmWave for the S20, Plus and Ultra devices on June 4th. They're labeled as S20 5G UW Models, other carriers to follow. A couple of drawbacks for the S20 Base Model, you're limited to 8GB of RAM and no MicroSD.

Not sure if anyone experienced this. I bought my S20+ 5G in Sweden (SM-G986B/DS). Recently I'm traveling in China and I noticed that, even there's 5G coverage and i have a sim card which support 5G and i have turned the 5G switch on. I still cannot get 5G signal on my mobile.
I did some search and my carrier is using N78 and SM-G986B/DS supports N1 (2100), N3 (1800), N5 (850), N7 (2600), N8 (900), N28 (700) N40 (2300), N77 (3700), N78 (3500)....So there should not be a problem for my mobile to pick up the signal.
However, a S20+ China/HK version (supports 5G bands N41(2500),N78(3500),N79(4500)) can pick up the 5G signal with same sim card.
So i start suspecting actually there's a lock which preventing my mobile to pick up 5G signal. I read some report that some China version of 5G mobile, such as 1+8 china version or Xiaomi 10, also cannot pick up 5g signal in Europe, even they share the same band...
And that's really getting annoying... Is there a lock? It's a hardware lock or software lock?
In Samsung phone there is Carrier Policy limit bands, features etc per carrier like other devices. I have instruction how you could check supported bands, carrier aggregation and 5G support connected-network with Samsung devices: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices . Without modem log hard to say.
S20+ China/HK-version: https://cacombos.com/device?model=SM-G9860 works at least in China Mobile 5G-network.
Based on your observation of the carrier bands, I'd say the mobile providers in China are using using either N41(2500) or N79(4500) for 5G. Checking the list of bands used by country on Wiki, China Mobile is using n41 (and maybe n79 as well), China Telecom is using N78 and China Unicom is also using N78.
Which mobile company are you using?

It's China Unicom and it's N78. According to the Samsung website, N78 is supported by SM-G986B as well. That's why i'm confused.

Thanks, will try to have a look. and it sounds like even the mobile supports the bands but it's still cannot pick up the signal because the carrier is limited?

This could be possible situation. If you like to get modem log from your device there can see if it support 5G in used network. That is only way. Here is instruction: https://mt-tech.fi/en/how-to-get-4g...tions-from-your-android-phone/#Exynos_devices .
