Hello, I have a strange issue with my device SM-G9880. I could not get 5g to work on sim1. It works only on sim2 slot. The option is available on sim 1 but does not connect to 5g. Any thoughts would be appreciated.

Kuwait, ooredoo. Im not sure if its relevant since it works on sim 2 already. But it is strange honestly.
Can confirm the same here with the sm-g9880 Hong Kong model. I have a Telstra Aussie Sim that supports band 78 5g. Will only work in second Sim tray. Very strange. I'm guessing this is some kind of bug?

It is a bug, and hopefully can be fixed by a software update

Just to let people know though. Once on the Hong Kong CSC , it doesn't support band 28 aggregation so won't do 4g plus . Another strange thing considering band 28 (700) works by itself.
Here are the bands support as confirmed by samsung Hong Kong

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?

No CA with Band 20 and Band 3. Only Band 3 and Band 7 paired sometimes.

Try changing CSC to 'TGY' or 'BRI'?
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 !

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).
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?

You might be able to flash that countries firmware to the phone.
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.

Hi everyone,
I got a S20 Ultra (Korean version) as it was one of the few with Snapdragon to work on UK bands but I am struggling to trick the phone to show me content in english on native apps (Samsung Daily, Weather, Members app...).
Don't get me wrong, the initial content is in english but once you try and get more info, about the weather for example, it takes me to a korean website. Members is in Korean all around and daily has Korean cards inside.
Which I think is normal due to the Korean CSC.
I changed the CSC from SKT to KOO but it only removed the network branding and default carrier apps.
Is there a way to bypass the CSC or install an English CSC from UK for example?
did you find how to change it ?
Also have the same issue. I am in Australia. I was thinking about installing australian firmware?
I have an SM-G9860, which is the Hong Kong S20+, and live in Romania. Anyway, I'm pretty much in the same boat as you, having the TGY csc instead of ROM or ORO. Samsung Weather sends me to samsung internet to accuweather.com, which is just what my old exynos s10+ would do, and samsung daily seems about normal, with only the spotify recommendations card showing something in chinese. On the other hand, Samsung Members, which had been acting like I was living in Hong Kong (showing me the offers from there and so on), has, since a few days ago, started showing me content from Romania. Upon randomly launching it last week, it gave me a message as such: "App might reset due to regional settings change" or something like that. My csc is still TGY and samsung pay for instance still is the hk variant. Other than that everything is pretty normal.
Thats why I was asking if its possible to dowbload firmware for the Australian version of the S20 Ultra which is not snapdragon (the reason I bought Korean version because it is snapdragon). Will things still function as normal if I put on Australian firmware that is designed for a korean phone? Sammobile has the firmware for all countries spec phones.

No. Quite simply put: You can only flash Firmware intended for that specific handset.
For example: I own the SM-G9880, which is the (snapdragon 865) Asian version of the S20 Ultra 5G.
I can only flash three firmwares: TGY (Hongkong), BRI (Taiwan) and CHC (China "open"). NO other firmware. Certainly not, say, the EU Firmware, which is for another CPU entirely (Exynos 990)

Thanks Roman. For example I cant use Samsung Pay because it says 'cards must be from Korea'. And a few other things of that nature.
Firmware of a US s20 Ultra running Snapdragon chipset wouldn't work either?

The same way I can't use it because I'd need a card from Hong Kong, but I just use GPay instead, works like a charm. Nope, nothing, I'm afraid. You can only flash the Firmware intended for that specific model number. I am in a slightly different conundrum - I got the SM-G9880, and I'm using it in Europe. While LTE and 5G bands are similar, they aren't identical. LTE, it's barely noticeable, since 1,3,7 and multiple others are supported, 1,3 and 7 work in 4x4 MIMO and the most important Carrier Aggregation Combos like 7-3-3-1 (12) work too. Only thing I don't have is CA with Band 20 (only supported in single mode) and on the LTE side that's basically it - I even have 28-7-3-1. However, 5G wise, different story. Only Bands I got for the EU are N1 and N78, which luckily is exactly what my carrier uses, but there might be N3 and N28 down the road like in other EU countries so it'd be nice to have that...

Hi, i'm about to buy online an S20FE 5g (preferably an 8GB), and i was wondering about the differences between different versions; i don't know what should i buy to use in Europe.
I could not find a comprehensive list, so i thought i could just post what i know; the more info you can share, the most complete the list will be.
SM-G781B (International)
SM-G781U (USA)
operator locked, should not buy for Europe
SM-G781U1 (USA Unlocked)
not a real dual sim (as stated here)
SM-G781W (Canada)
SM-G7810 (China, Hong Kong)
for this version there's a 8/128 model (is it good to use in Europe? they seems to come at a cheap price)
SM-G781N (Korea)
SM-G781V (Verizon)
Also, the /DS stands for "dual-sim hybrid tray" i suppose, based on this evidence
Based on this, frequencies support should be the same for models SM-G781B (International), SM-G781N (Korea), SM-G781U (USA), SM-G781V (Verizon):
GSM frequencies
850 900 1800 1900
Standard UMTS
850 900 1900 2100
Standard LTE
FDD LTE: 2600, 2100, 1900, 1800, 1700, 900, 850, 800, 700
TDD LTE: 2600, 2500, 2300, 1900
Standard 5G
FDD 5G: 1900, 1700, 850, 600
TDD 5G: 2500
The one listed on Bestbuy is SM-G781UZBMXAA. Can I use that outside of US, in Asia perhaps?
I got SM-G7810 , I am from Poland and it works just fine. Bought it from my local phone store with their warranty. Got it much cheaper. Works ok, no problems.
Just waiting for android 11, looks like HK is less important to Korean company then Europe

Got the same phone delivered since a day in the Netherlands. Works fine, every language possible to choose, works fine on the networks etc.
I'm just trying to find a way to flash a ROM with another CSC to try to enable THL ( Thailand CSC) as to make phone-recording possible. Seems not easy to get rid of the Hong Kong CSC.
Even with some 'CSC change tricks' I don't get any further than to choose for TGY as the only one in the list.

Hello,
Can any one confirm they get 5G on there Samsung Galaxy S20+ G9860 Hong Kong version on the o2 Network? This is with the latest firmware.
I have just moved on to a 5G plan on o2 and whilst in many o2 5G areas I never get 5G. It goes to 4G+ but never 5G. I have a new 5G o2 sim etc....
I'm running on the latest TGY firmware and for a short period changed my CSC to BRI and loaded BRI firmware but didn't make much difference. It never went to 5G.
As soon as I put a 3 network sim in I get 5G on sim slot 1 and 2 all day long in 5G areas.
Does anyone actually get 5G on any phone with o2?
Thanks
