Hey, is eSim working on it? (I like to change my CSC on my Korean SAMSUNG Galaxy S21 Ultra (SM-G998N) to a CSC which support esim (Now only 1 physical sim, no e sim option, sim manager is not visible). SamFW tool says Available CSCs are KTC | LUC | SKC | KOO | WWD. first 4 of them are koreans. so wont work. Any idea about WWD CSC. 1) which country it belongs to 2) will it support eSIM 3) will it disable any existing apps-Gpay,Bank apps or cause any other issues 4) will CSC Change reset my phone and have to install and configure all apps and data again?

I do not understand how people blame Samsung for them importing a phone and using it in an unintended location to the point people are flashing software not intended for said model.... There is a ton of regulation involved in each specific country in regards to mobile services... People expect Samsung to cover each and all regulation across the entire world?... Is there specific knowledge that Samsung disabled the feature?.... When dealing with imported models and flashing different firmware YMMV.... I've imported phones for 10 years and understand that unless I'm buying the Japanese retail version, I will have to deal with anything that comes from importing another regions model... Sorry for the rant :)

Of course they are to blame, the moment they decide to push retarded cpu to certain countries.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cezeff:
So rather that flame, cuss out Samsung and so forth, the purpose of these forums are to try to find root to the problems and ways to improve the phones... Plain and simple if you use a phone in another region other than it's intended, YMMV... If I take a N20U from America to HK and expect it to work, that doesn't make sense. Someone mentioned other phone companies that market their phones as unlocked global editions... Samsung is now advertising the N20U HK as global unlocked edition for you to go globe hopping....

Back to the situation at hand .. Has anyone tried placing their 5G sim card in the second sim tray after the update?... Another user in a different thread stated they had to clear some sim settings/phone settings to get 5G to work ... Has that been tried?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] androidlover287:
Fact of the matter is - the frequencies are N78 for 5G that is the SAME in most European and Asian countries for 5G. so if the 5G works in Hong Kong AFTER the update, it should work regardless of where the phone is, as long as the country/network uses band N78 for 5G. Simple as that.

4G/4G+ is working absolutely flawlessly and BEFORE the update (though I didn't test it myself) 5G was working fine, it only broke following the update and I guarantee that is the same for Hong Kong users as well, it's not possible to lock a modem to only work correctly in specific regions, though I could be wrong.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] evenshop:
Yes I did try to put it in the second slot. I tried everything under the sun. What do we have to clear exactly ? Can you give a link to the thread ?....
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
Not in my case here in Philippines using Globe Tel sim.

You can check 4G CA by dialing *#0011# with mobile data turned-on. You will see those CA-A* lines indicating the bands and the BW.

It will usually indicate "4G+" or "LTE-A" signal in the status bar.

I love to think this way but learning that this has been the same problem S20U 5G hk variant users are experiencing since few months ago and still unresolved today makes me think the otherwise.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cezeff:
Here's a thread with users facing the same issues...https://xdaforums.com/galaxy-note-20-ultra/help/getting-5g-volte-sm-n9860-hk-note-20-t4157577

It also has a few install tips.. In general you want to factory reset, then boot the phone into recovery and clear the cache...https://help.republicwireless.com/h...Android-System-Cache-on-Samsung-Galaxy-Phones

Then at that point try flashing via Odin and do not restore from any backups, try a fresh clean install with your sim in the second sim card slot...

I hope you can get it working... One user was saying that it could just be a bug... Could be regulatory issues, yet I haven't seen any issue like this expect a few threads in this forum... Sammobile has not brought up anything as well... I'm hoping it's just an activation issue via software and network...I don't see Samsung just turning off 5G on a 5G phone.... I'll keep looking around to see if there are any solutions that pop up.... What country are you in? And is 5G that widespread where you are at?

---------- Post added at 07:42 PM ---------- Previous post was at 07:34 PM ----------

Good to know....I think CA also depends on what bands are compatible...I spent a good amount of time in PI before, been a year or so since I was, has cell service across the country improved? Globe always seem to have the best service.

---------- Post added at 07:50 PM ---------- Previous post was at 07:42 PM ----------

I agree with you... Just because it's the same band doesn't mean that the MHz are being allocated the same in each country.... I will say 5G is a very niche thing at the moment.... Still a lot of growth... Here in Japan it's barely available at a few major cities.... It's flashy yet not at all a huge selling point here, I don't even see it on the main page of Docomo website...I hope you can get the 5G service you are looking for... Please report any breakthroughs

---------- Post added at 07:56 PM ---------- Previous post was at 07:50 PM ----------

I'm not saying that the 5G shouldn't work... What I'm saying is rather than cuss Samsung to high hell, so deduction should be done.... I also want to note the risk that if something bonks on an imported modeled, it should not be a surprise, it is imported after all.... I'm thinking that the 5G should work and shouldn't be turned off and looking for a solution as to why? Not really seeing widespread cases reported.... Some say it could just be a software bug.... Hopefully it is nothing more than a software hot fix and call it a day.... I'm about to see if I can dive into some HK forums and see if they are having the same issue

I've tried once again. I had 5G with July FW, then I applied the update (once with OTA, another by flashing Aug. FW with Odin). Nothing changes, whatever I do (factory reset....), 5G is disabled once the upate is installed....
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] roryh86:
Actually, I just received my N9860 today. I also have the Exynos version. So after setting up the N9860, I checked the firmware version installed (see screenshot), and it was N9860ZCU1ATGM with July 1 update, which I believe is the base firmware. I checked for update, there was an update but I didn't install it.

I took my Exynos UK N986B and my new N9860 to a nearby 5G mast. My SIM was in my UK N986B, and it was receiving good 5G signal. I removed my SIM and put it in the N9860. There was no 5G signal. I got 4G signal and sometimes 4G+ (so aggregation out of the box), and VoLTE works no problem.

I tried the SIM in Slot 2, no 5G signal. I tried locking the signal to n78 band, no 5G signal.

My point is, even on base firmware without update I was not getting any 5G signal.... Even though I was getting 5G on my UK exynos in the same location.

So it doesn't look like it was the firmware update that stopped the 5G.

One point about the aggregation. In my house, my exynos switches between 4G and 4G+ frequently, but my N9860 is only getting 4G.

Not sure why because I had aggregation outside my house. I'm with Vodafone UK. So I dont think its working perfectly on the N9860 but it worked when there was a strong signal.

p.s Im reading elsewhere that people got their 5G back by installing BRI firmware (although it seems he cant update anymore OTA). Has anyone tried to install BRI firmware?

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VirtualWaver:
I think is that MAYBE the mhz are different even though the band is n78.

If we look here: https://en.m.wikipedia.org/wiki/List_of_5G_NR_networks

It says that in HK they use 70hz and 80hz for band 78, whilst, for example, in the UK they use: 40hz, 50hz and 100hz for the same band 78.

I wonder if this is the case and if so, it might a software limitation (disabling all other "unused" mhz?).
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] theholyguy:
I pretty sure it's software problem, the same SoC in all others brands works all over the world in 5g... is Samsung messing the things again.

Enviado do meu SM-G9650 através do Tapatalk
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VirtualWaver:
True, but in this case the issue can be related with missing driver or some other file missing from the firmware not just an existing file that has the value set to false.

Its something we need to experiment with to find out.

I could flash BRI CSC and test but have no 5G in my area.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dr.mz:

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jtOttawa:
Asking an off-topic question in a thread is called 'hijacking the thread' - which you shouldn't do. That said, there are other threads that address this question - just search for them.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VirtualWaver:
This site is also good. It seems that n78 band itself uses different frequencies. When I check my operators 5G details here https://3g.co.uk/guides/what-frequencies-does-three-network-use it says it covers 3400mhz (band 42) and 3600-4000mhz (band 43) whilst n78 is 3500mhz and even UK exynos doesn't have band 42 and 43. So it's a bit confusing at the end.

However, as dr. mz posted above, it worked with default firmware so it is definitely a software thing. Which is very good thing.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jtOttawa:
I think so as well, as if I understand correctly, the X55 modem is capable of the full spectrum of frequencies - it's just a question of which are enabled via software.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] VirtualWaver:
Strangely, for me the Note 20 has better signal and carrier aggregation as my old Exynos S8.

Might be related with signal strength and newer modem though.

A funny question - have you tried to reboot your phone after inserting sim to sim2 for 5G? On Samsung's website they recommend to do so in case if 5G not showing up. It really shouldn't be like that but who knows?

Also, do you have power saving mode on HK? Some of that settings disable 5G. Try to insert sim1z then disable 5G on sim 1 via settings - connections - mobile manager and then remove and install to sim 2 and enable 5G on sim 2 via the same settings - might trigger it. But I am just speculating here.

Offtop: I think we were discussing this 5G thing on YouTube on Orr Weisbergs channel haha.

---------- Post added at 01:40 AM ---------- Previous post was at 01:39 AM ----------

True. A bit strange that one person got 5G with the default firmware but some other didn't. Might be operator specific thing too...

As someone suggested I think our best bet would be digging in HK forums to see if HK users have the same issue. Will clarify things...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] roryh86:
n78 is range from 3300 to 3800 MHz currently used for 5G. Some of the lower end of that band is/was also used for LTE (4G, band 42), so there is an overlap. I think they have redesignated those frequencies to 5G so that 4G is now mainly on band 3 and 20, and some on band 1.

---------- Post added at 02:21 AM ---------- Previous post was at 02:08 AM ----------

Haha yes we were! I got the Snapdragon phone today. Haven't had much time to mess with it. I tried sim2 but didn't try to restart. As someone mentioned earlier on this thread, the N9860 isnt really designed for this region so it makes sense that we are facing these issues. There is probably a lot more software configurations built into the phone/CSC to make it work with the local networks, not just having the n78 band.

But hopefully they will fix it, because honestly 5G is pretty good and I dunno how I could justify spending that money on the ultra and not having 5G. Also, the 4G is worse than my Exynos so..

We really need a fix to make this modem function properly in the UK. At the moment I'm still using my Exynos until there is a fix.

I ran a few benchmarks and it was much faster than the Exynos. Even disk read speed was 1750MB/s compared to Exynos 1050MB/s. Camera shutter lag was slower on Snapdragon which is probably why a lot of YouTubers complained about that. Exynos has a faster shutter. Although might be fixed with an update.

Hello, I can assert that's a software issue, because I have 5G with July Firmware. I noticed something weird. Even after changing CSC with the method described in this thread (TGY to BRI), the phone is not 100% BRI (in the software version info, you still have TGY mention, whereas you should only see BRI in a "real" BRI phone...." Maybe that's a part of the explanation... I tried to flash the July BRI firmware (instead of the TGY), but it didn't solve the issue.... If someone has an idea....https://ibb.co/t3SKdjM
