S21 Ultra 5G (SM-G998B/DS) - UK Purchased - Moved to Hong Kong - No 5G. - General Questions and Answers

Hi Folks,
I've benefited from awesome information here over the last few days as I embarked upon a trip down a huge rabbit hole.
However, my issue isn't resolved and I'm at my wits end - so would really appreciate a pointer.
My situation:
1) I have the S21 Ultra 5G (SM-G998B/DS).
2) I purchased the phone in the UK, then subsequently moved to Hong Kong.
3) 5G was working fine in the UK on "3" network. I acquired a 5G "3 HK" contract here.
I am not getting 5G signal at all anywhere in Hong Kong, only 4G+. I have tried all of the normal fault finding - APN settings, clearing cache partition, general settings - nada.
Signal checkers seem to indicate that the SM-G998B/DS should work in Hong Kong with 3.
My main problem - I think I need to remove the NR whitelist from the service mode, but:
1) The standard dialer service mode *#0011# does not have any options for UE menus.
2) The Google Phone dialer service mode *#*#276633683782#*#* is completely empty.
I can't get to any place to remove the NR whitelist.
Does anyone have any suggestions on getting this to work? I've been sitting with Samsung and 3 customer support, but their shop-level support isn't really cutting the mustard, and they don't really know if SM-G998B will work in Hong Kong.
Thanks so much in advance.
Scotty.

Just to update.
In my desperation, I strutted over to the store to consider buying a Hong Kong S21 Ultra (assuming it would be SM-G998O). Buying a new one would break my tight-fisted Scottish heart, by the way.
Imagine my surprise when the display model - booming along on 5G - was the SM-G998B/DS. My exact model.
The very knowledgeable girl in the store played around with mine but couldn't get it to work on 5G.
She thinks my work profile with the Tunnel VPN might be blocking 5G. Does anyone think that is possible?
I've already started in mode - which did not yield a fix, so I had discounted this option.

The other thing that is on my mind is the CSC.
My current CSC is BTU (UK, I believe). Would switching the to Hong Kong CSC accommodate the 5G connection in Hong Kong?

Advice on buying Galaxy S8+ SM-G9550 6GB version for european market

Hi All,
It's been a long while since I have posted something, but I have been using and reading up on XDA with much gratitude since I joined in 2010. The community represented here is just awesome in every way, and I would like you all to know that. I wanted to ask you guys for advice on the following matter:
I currently own a galaxy note 5 in the Netherlands, which I have purchased in Dubai. I decided on the dual sim model, since I find the dual sim capability for my work and private sim very important. The phone has done me well in the last 18 months (worked without any trouble in NL, and is rooted), but now I think it's time to replace it. My new phone of choice would be the Galaxy S8 plus, preferably the 6GB model. Of course this would also need to be the dual sim version, otherwise I could just buy the normal version here in the Netherlands. I have some friends living over in Hong Kong, which would allow me to buy the phone there.
Now for the hard part. Not only does the phone need to be dual sim, it also needs to support all dutch bands (including volte if possible) and it must be able to be rooted (adblock on its own is enough reason to justify that, let alone all other possibilities). I am used to flashing kernels and roms on my phones, as per the consice instructions found on this forum.
The phone that meets my criteria seems to be the SM-G9550 (6GB) that can be bought in Hong Kong. Would you guys please advise me on whether you think that would function here in the Netherlands and whether I can root it? And if not, what would you advise me to do given the above?
Thanks a ton in advance
@kimi4life
The G9550 is the Chinese/HK variant of the GS8+, and while it does support LTE Bands 3, 7 and 20 (those used by Vodafone NL), the combination of bands, known as Carrier Aggregation (or 4G+), may or may not work. Moreover, VoLTE and WiFi calling (if applicable) will NOT work with this variant.
The reason behind this, is the CSC. Since the G9550 is only sold in China and Hong Kong, it does not have a Netherlands CSC (Carrier Specific Customization), so you'll have all Chinese and possibly even carrier bloatware for China.
There is a way to get a G955FD CSC (EU variant) on your G9550 (CN/HK variant) phone by rooting it and flashing a custom ROM and CSC switcher, you can check Nicholaschum's thread in the Discussion section on how to do that. Do keep in mind that doing all that voids KNOX and there is no way to reset the KNOX counter.
However, the Chinese variant has no custom ROMs, and you'd be better off with the Exynos G955FD variant.
I wouldn't recommend going through all the trouble though, the 64GB/4GB S8+ is pretty good on its own. If you pick up a G955FD, and pop in a Netherlands SIM card, it'll automatically switch to the right CSC based on your country and what carrier you're on. This variant can be rooted, has a few decent stock based custom ROMs, and gets software updates more often than the Chinese variant. You will also have no issues about LTE band compatibility since the 955FD fully supports all networks in Netherlands.

Thanks a ton for the clear explanation! It would seem the G955FD would be the best choice then. I'm not sure if these are also sold in HK, i'll just check online if they are. Small bummer on the storage space, since I've heard it is not expendable when using the second sim. Then again, if I go abroad I might as well switch out one of the sims and place an SD card.

955FDs aren't available in HK, but the dual SIM S8+ has been launched in the UK and is available in Dubai as well.
In fact, I bought my 955FD in Dubai as well.

Thanks again for the advice! I'll get back to you on the best way to root when I received it
my friend is brining me over a G9550 from HK over the weekend. o2 in the UK have not cleared the s8/s8+ for wifi calling and volte yet, but when they do, where is the link to root and install custom rom and csc on it so i can hopefully get it to work with these services?
im getting the phone for free, so i can't complain with free!

will the korean exynos firmware or custom rom built for that device even work for the snapdragon G9550?!
No need to root for adblocker, you can get adblocker through "Adhell" or "Disconnect for samsung browser" in play store. I don't think rooting is worth it on such a new device with many functions out of the box. Substratum also got samsung support without root.

That's odd considering it supports the necessary bands.
Have you set it to LTE mode?

I thought it would support it straight out the box too but it only connects to 3G:

You sure you have the APNs right?
Dial *#2683662# and tell me if a Service Mode menu pops up.
Erm I did get some OTA configurations when I put my Vodafone sim card in but I didn't accept them settings as it was browser changes and I didn't think they affected my data connection, could they be it?
It said:
service mode
menu not exist
press back to continue
current command is 1000
Edited to add:
I just looked in my access point list in settings and it does come up with Vodafones access point settings
Edited again to add:
I spoke to Vodafone who checked my APN settings and assured me they were correct
Edited again again to add:
Added the APN settings manually, restarted my phone and now it works with 4G ?

That's because the Chinese variants don't support carrier aggregation on the same bands used by networks in the UK.
I have 4g+ in china and Hong Kong but not here on voda uk

Overall Compatibility in the US

Hey guys, so I was exploring purchasing a Mi Mix 3 on Aliexpress for use in the United States. However, I had some concerns about usage in the United States, especially with the international version. Could someone please tell me about their experience with this phone in the United States, including carrier signal (preferably T Mobile), any issues you've come across using this phone in the United States, and other similar dilemmas. Thanks!
Its name Global Version for a reason, so i think it will work fine all around the world, IF its a true Global Edition.
Check carefully, many seller flash the global/eu rom on CN variant and sell them as "Global Edition".
It will work internationally whether it's a global edition or not, there's no difference in the bands between the Chinese and Global variants. The software is different, however. The Chinese software works fine in the US, but you have a bit of work to do to get the Google apps on it. The other issue is if the seller is buying the Chinese variant then loading the Global software and relocking the bootloader, because if you subsequently install an official update, you will hard-brick your device. Having said that, I can't think of any reason why sellers would be bothering with that now that the Global version is readily available, at least the more reputable ones. Gearbest always clearly mark their devices on the website as either Chinese or Global. I suppose if you wanted to be absolutely sure, you could buy from a European retailer, assuming you don't want the 8/256 model. The other option, of course, is to unlock the bootloader and (optionally) install an unofficial rom, that way you also get regular Android security updates.
I would recommend spending the extra to get the 8/256 if there is any chance you are going to get a "chinese" version. The "global" version is *supposed* to have all the bands enabled on all storage/ram configurations. However, the chinese version only has full band support on the 8/256 device. It is possible that we may be able to find a way to use QXDM and stuff to enable additional bands regardless, but I wouldn't count on that. I spent the extra to get an 8/256 which now has the leaked global rom on it. The global software works great and I have atleast equivalent coverage to my work Pixel 2 XL, usually with slightly better signal levels.
I have no complaints about this device, the only thing I have noticed is it seems that the glass is not as hard on some units. I bought my wife an 8/256 device and she is not exactly gentle on her device. Her screen has no scratches, but mine has many already after about 2 months, and I'm pretty careful with my devices. And to be clear, these are light surface scratches that are only visible when tilting the device with the screen off, not something you can see with the screen on.
I have T Mobile. I get better reception on Mi Mix 3 than I got on both my Note 8 and my iPhone 7. I know this because there's a spot I park every day and the MiMix works there when the others didn't.
I got 96mbps on 4G LTE when I tested it.
Of note: I did have an original MiMix 1 and it was not good for reception. At all. But the 3 has something like 42 bands in, and it has the best reception of any phone I've had.

So I just want to confirm. If I buy a mix 3 in China and then flash itd to a global ROM (e.g. EU) then I should have no issues using it in the US (I'll be on T-Mobile).
There is a serious problem to me not sure if it's because of Mi MIX or TMobile combination (Los Angeles area)
Same problem on my wife's MIX 2S and my MIX 3, both official global version and latest firmware.
When the phone is on wifi, even though the mobile connection looks connected, it might have been disconnected actually.
No call and message will come through. People's calls will go to voice mail.
You will not know that until someone tell you they can't call you on the phone, or when turning off wifi suddently all missing text/MMS messages will arrive.
I'm still searching on more information on this and if some others have the same issue.
One of you friends used to have similar issues using a Samsung Galaxy on TMobile before he switched to iPhone.
Working great here in MN on T-Mobile no issues at all. I have the global edition.
It works for the most part on Verizon (a carrier which doesn't technically support it), the only issues I have are with MMS messaging (which is fixed in another thread) and my mobile hotspot which Verizon seems to be unable to turn on properly. Other than that I haven't had any issues. I would imagine on a GSM carrier like T-Mobile you would see even fewer problems, if any.

All you need to do is pop in a Verizon SIM card and change the APN settings and it'll work. Sometimes the SIM card won't let you change them (because Verizon locks them down), but that didn't happen to me. If that's the case, grab someone else's SIM card that has like T-Mobile, put it in your phone, add a new APN, then put the Verizon one back in and select the APN you made. I detailed the settings you need to set in these posts: _1_, _2_. If you need any additional help let me know.
Also, if you want to enable VoLTE check out this thread.

[5G/esim] Regional Lock

Hello there,
The first users began to receive their devices by pre-order. In several regions, it was found that the device is being sold without esim and 5G support. For example, in Africa and the CIS countries. After numerous complaints from users, Samsung promised to unblock esim in two weeks, but according to them, 5G modem is physically not there. This directly contradicts what was said at the conference about a single model for all. The device model (SM-F916B) and firmware are exactly the same as those sold in the UK or Germany.
In the modem firmware code in the region settings, the line is simply removed:
[FIRMWARE.ZIP]\[CSC_FILE]\optics_\configs\carriers\single\[REGION_CODE]
Code:
<CscFeature_SystemUI_ConfigOpBranding5GIcon>5GAvailable</CscFeature_SystemUI_ConfigOpBranding5GIcon>
Could someone with a working 5G show their build.prop file? I suppose 5G is also programmatically blocked, but I need proof.
build.prop
Code:
C:\Program Files (x86)\ADB>adb shell
f2q:/ $ getprop
...
[persist.radio.multisim.config]: [ss]

This z fold 2 is from germany:

I was told so on the Samsung hotline. For example, the Italian version has a similar problem with esim.
Are you saying that the version sold in the UK does NOT have the 5G modem? How can they be selling me a Galaxy Z Fold 2 5G if it doesn't have 5G?
If this is the case then, seeing as they have already pushed my delivery back I am going to cancel my order and carry on not using Samsung phones.
I am not with EE in the UK but their pre-order information for the Fold 2 states "Pre-order the 5G-enabled Galaxy Fold2" so surely it must have the modem or they will have a lot of angry customers.
Just checked Carphone Warehouse here and they have it listed as being 5G.
Maybe I misunderstood or the information isn't accurate?

All Snapdragon 865 (or plus) are built in with 5G modem, that is one of the reason for higher prices of Flagships this year. So 5G modem is there but in some countries it's disabled via software
Since this phone only comes with Qualcomm processors, Samsung is forced to pay around $80 for a 5G license per device. According to a source close to Samsung, they decided to save money in some countries.
Got my Z Fold 2 5G yesterday (in Netherlands) and there is indeed no esim. The box has 2 IMEI listed, but the phone shows only one. No "sim card manager" inside settings menu either. I called samsung "premier support" this morning and they had no clue. the support rep gave me a complete non-sense reason (i.e. esim is not allowed by the carrier - lol) and I very quickly realized there is no point arguing. I hope they enable it in 2 weeks or mine is going back.
I received a confirmation from Samsung Moderator from Samsung community website.
The phone is compatible with esim.
The problem will be solved via an update.
Update is currently in test and validation phase.
But 2 weeks seems a little bit long for a premium device.
Have you 2 IMEI or one?

Thanks for the good news.
I have 2 IMEI listed on the box - and samsung confirmed that it's a dual phone / esim model. Can you please reference the community thread?
I got mine from Samsung Portugal. 5G is enabled (but we have no 5G network yet) but no esim. I have 2 IMEI listed on the box btw. Indeed the Sim card manager option is not there. I called Samsung and they have no clue why it is not there. They will call me back in 1 hour. I will let you know. This is kind of dishonest from Samsung. Selling a product like this one and not telling users that all functions they paid high price for, are not available right out of the box. I am feeling as bad as when I got my S20 ultra with all the camera defaults. I have 2 weeks to send it back. telling us that it will be available within 2 weeks is kind of weird.
I received my UK model today - 5G is working fine, but no e-sim/sim manager etc. Fingers crossed they get it sorted soon - the official launch is tomorrow, you'd think the carriers would be pushing them to resolve it for then!
What does it mean if you only have one imei number?
/CK
E D I T :
I have two imeis on the phone box/case but only one in "About phone"
Waiting on eSiM solution too - agree not cool to advertise and sell with a major feature missing - phone is great - just need 2 sims if I want to use it as my daily driver ...

Steps to get the SM-N9860 optimal for UK use

Hello all,
I have recently purchased a shiny new Hong Kong version of the Note 20 Ultra 5G (SM-N9860). I am based in the UK, and want to get the most functionality out of the phone, namely:
- 5g capability on the Three network
- Samsung Pay working
- inbuilt call recorder
- VoLte working
I have had a read through various posts on these forums, and it seems I would need to do one or both of the below:
- Change the CSC using the Google Dialler trick
- Change the firmware using the patched ODIN tool, and a firmware from Sammobile
Now my question is threefold:
- What combination of the above two steps do I take?
- Which region do I change the CSC and/or firmware to (UK or otherwise)?
- If I have to change either the CSC and/or firmware to a region with the exynos variant, will that cause problems, as the SM-N9860 is the snapdragon version?
Thank you for bearing with me
I have the same phone. There's a menu hack code to get 5g working (whitelist) and it's fine for me (Vodafone UK), although I disable it as it rips through the battery. I think that works for Vodafone and EE, but not sure about Three as they might use a different band. Wouldn't touch them with a bargepole anyway.
Samsung Pay let me register my Nationwide UK card with the HK portal. Took a few goes but it works fine now.
I'm very happy with the phone (no idea what VOLTE is) and I don't need call recording. All works without changing the firmware.
Voice over LTE = Volte

How did you register your uk cards with samsung pay hk?
Just put the details in and it accepted them. I really can't remember the process as it was so long ago.

Thanks, also where did you find the menu hack code for 5g
It's on Google. Just search for Note 20 Ultra Hong Kong 5g whitelist or somethig like that.

Question Using an Indian bought S22 Ultra in the UK

Hi all! Hope you're well and safe.
I'm moving to the UK soon and bought a S22 Ultra a couple of days ago. Did not find out about Samsung's inexplicable and baffling region locks on the phones and certain features (Samsung Pay, etc.) before I bought the phone. Consequently, I've been researching on all issues I think I could face once I move to the UK later this month. Had a few questions about the same, so thought I'd reach out for help here.
a) I understand that Samsung Pay will not be available in the UK on my Indian S22, due to the region lock. Is this correct? To clarify, I don't intend to change the CSC if I'll only be losing Samsung Pay, as I'm sure Google Pay will be sufficient.
b) I understand that UK S22s are Exynos-based and not Snapdragon-based. Therefore, am I correct in assuming that I will be unable to flash UK firmware on my device, due to the SoCs being different?
c) I'm using a Samsung Galaxy Watch 4. I tried installing Google Pay on my watch, but was unable to find the app on the Play Store. Further reading led me to Google Pay's website, which states that Google Pay for Wear OS is only available in select countries, including the UK, with India not being included. Would I be correct in assuming that once I change the country on my Google account, I will have access to the app on my watch? Also, would the watch automatically have access to apps in the UK once my Google account's country is changed?
d) I understand that the international version of the S22 Ultra (which I believe is the model I'm using) will have no problems connecting to 5G networks in the UK, since most networks in the UK use band 78. Can anyone who's travelled to the UK confirm if they've been able to successfully access 5G networks in the UK on their Indian S22s?
Thank you for taking the time to read this post. Grateful for any help I can get!
Cheers!
If your device is SM-S980E which I belive is the Indian & International model , then it will support 5G in UK for sure. Both the European devices & the International ddevices support the same 5G bands , they used to be the same version before.
Samsung pay should work But you won't get Uk exclusive offers
Google pay will work once you travel to UK
Hi OP. I am moving to UK too in a fortnight. Were you able to change the country code?
a b c yes
d likely because Indian (E model) and UK (B model) have same 4G/5G bands.
