Global ROM in China? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &
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.

Hold on,
can you check the following please :
Settings -> Connections -> Mobile network and tell me if you can choose 5G on your SIM. Thanks
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.

I just did it regardless of it being supported.
I'm on TGY now and i have 5G and the caller id\ spam protection options, but still no carrier aggregation, one step closer,

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.

[Q] Asus Zenfone 2 ZE551ML MODEL ASUS_ZOOAD 3g
I need help, i want to buy a zenfone 2 from alegrecompra, but i dont know if the version Z00AD support 3G wcdma, i live in latin america. Does anyone has bought this version?
I made a similar question but nobody answered. I understand that if your buying it from a Chinese based site you will get the CN version. CN version definitely lacks many LTE bands support compared to TW or WW version, but apparently it supports the same WCDMA bands as the others, and, on top of that, it also supports TD-CDMA bands only useful in China, but never got any confitmation first hand, only real way to tell for sure would be if someone with that CN version confirms they get WCDMA coverage with a provider using the same bands as your company... It would be wiser to get the TW version instead but its harder to find an online store selling it apart from eBay sellers and also it should be a bit more expensive I guess...

@OP I suggest you buy the Zenfone 2 that you mentioned in your post. That is an America Version that can be used in Latin America as well. IMHO, do not buy the China or Taiwan Variants as those were specifically for Asian Continent. Good Luck.

Add LTE Band 3 to OP3?
Hi guys, so after a bit of research I found that you can add/enable bands on the OP1 as shown here http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031 and Here http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455 My question is can I add LTE band 3 to my OP3 A3000? Mine currently supports: North America model(A3000) FDD-LTE: Bands 1/2/4/5/7/12/17/30 The other models support: Europe / Asia model FDD-LTE: Bands 1/3/5/7/8/20 TDD-LTE: Bands 38/40 China model FDD-LTE : Bands 1/3/7 TDD-LTE: Bands 38/39/40/41 If anyone has done this or attempted to do this please let me know
Looking for the same information.
Also been searching for this. Found another thread which says hopefully in the next month or two it will be looked into. http://forum.xda-developers.com/oneplus-3/help/unlocking-lte-bands-t3425871

Any updates? I have a A3000 US model (Does not support LTE band 3) AND NOW I have just got a A3000 HK model (For my dad) (support's LTE band 3) and the "about phone" part is identical apart from the baseband version. Is there any way to tell them apart. And does this mean I can somehow unlock LTE band 3 on my US version of the OP3? If there was someway to backup the basband and restore it on on my US OP3 that would also be great!

Click to collapse It supports band 28 (700) but it doesn't pair with other bands for 4g plus like it normally should. Specifically band 1 and band 3 - they normally both pair with band 700 but they haven't been on this firmware.
Any update my 5g not working I only have 4g+ I have sm-g9880 and I. Using ooredoo kuwait
Im having this issue after the last update I dont know what samsung have. But i discoverd a fix if you want 5G u have To disable SIM 1 (Remove the sim or turn it off from the setting ) and use SIM 2 only then 5G will be back
were you able to get this to work? I want to order a G9860 Taiwan or hk model but won't if I can't use an sd card! Whatsapp and camera pics would rinse that internal storage straight away!
g9880 issue hello there, i have china version g9880 but i want to flash euro firmware, like g988b firmware, can i flash it? will the phone be able to boot up? what you suggest me to do, dual mesenger is showing only wechat, no whatsapp viber, any suggestion pllease

Hey there, today I tried using 5g in Germany (vodafone) on my g9880 with tgy csc. It worked only in sim2. Does anyone know when it will probably be fixed or know some kind of workaround? Thanks in advance !

Click to collapse so 5G on sim 1 was working before the update and they just broke it? I was just wondering if it ever worked on sim 1. If it did before,i guess there is hope they will fix it in the future.
Hi. Is this still an issue? I've just ordered a s20+ 5g (snapdragon).
Carrier Aggregation Combos
I'm trying to use an S20 (G981U1) outside of US, but can't seem to do CA for LTE band 3 1800MHz (B3+B3). I'm currently stuck with LTE on that band, it seems that this version isn't capable of CA_1C for band 3. Does anyone knows if this can be activated somehow? I've seen that for the S8+ was a method to add new combos , but I'm not sure this will work for S20 and I really don't want to mess with the EFS at this moment. Any heads up?

Samsung S20 5G (US) doesn't support 4G CA combos used in EU: https://cacombos.com/device?model=SM-G981U . And because Qualcomm version used in US, you can't flash EU-version firmware because in EU networks use Exynos.

S20+ 5G SM-G986B/DS cannot pick up 5G signal in China
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?

That's why i'm confused.

Click to collapse 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?

Click to collapse 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.
