anyone managed to get into and activate it
even with root, we can't use that menu
s10 exynos has crappy signals on t mobile
hoping i could change that
There is no way to change Samsung Exynos Carrier Aggregation. This is EU/Global model and i think it doesn't support CA with US Bands.
You can check supported bands and CA support when you collect log from your device: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/ . Please share log to https://cacombos.com/contribute then could list bands and combinations supported in US:
I have already some listed here: https://cacombos.com/device?model=SM-G975F but could missing some.

I have TMobile and have no signal issues. Even the US unlocked S10 doesn't support carrier aggregation, you'd have to buy the Tmo branded S10. I purposely went out of my way to get a G973F so I can have an unlocked bootloader and root. The only band missing from the G973F for Tmo is band 71 which is only a big deal if you live in rural areas. I'm in Massachusetts and there is no band 71 here at all. Considering the G973F has all the same bands as the G973U besides band 71 I doubt you would be getting any better signal with it unless you're in one of the few remote areas with band 71.
It mostly comes down to what your carrier provides in your area. For example where I am (Western NY) Verizon & AT&T I can get it however with TMobile I can't even get a 4g signal. I had an s9 (g960F) when I tested this and the same is showing for my s10e. I would strongly recommend trying AT&T.
is CA is working on snapdragon model
Hi All,
I have recently bought an Unlocked US snapdragon version of Galaxy S21 ultra 5g but I live in UK. Since the day 1, I have never experienced 5G icon on notifications area here in London. I only see LTE. My SIM is 5G enabled. Is there any difference between the US snapdragon 888 version and UK Exynos 2100 as I am not seeing this 5G icon.
OR, if someone knows if there is a chance to get benefit of 5G here in London with my US version.
I look forward to getting your answers...
Thanks,
If your version is dual sim, try putting the sim on 2nd sim card slot. Otherwise, I would contact Samsung about it.
I thought the US and UK used different bands and that is why Samsung use the different chipsets based on the countries 5G bands. There is a small overlap in the high bands around 27/28 Ghz but that would depend on the bands you Uk provider uses. That is why they do not recommend buying devices from abroad.
The US unlocked won't get 5G in Europe

Does it mean, I will never get a chance to to see 5G icon on my device ? Or I can get the 5G in the future when the 5G rolls out fully in the UK with different bands or frequencies? Please comment on this. Thanks

It would depend on many things, 1) The SD support your carriers 5G band, 2) the firmware supporting the 5G, 3) your plan with carrier supporting 5G.
(1) and (2) may be supported depending on the carriers bands, you would need to ask your carrier.
(3) for example, previous EE plans do not include 5G in the plan and only if you upgrade to a 5G plan can you connect at 5G. My last phone did not do 5G so the plan was a 4G plan, upgrading the phone meant I had to upgrade the plan.
It's not whether your carrier will add 5G, it's the bands that they add that matter. European 5G bands are not the same as US 5G bands. Samsung doesn't include both in a single version of the s21 (apple does). You either have the US version or the various global versions. I have the HK version. It's a snapdragon like the US (and dual sim) but it only gets 5G in Europe (and HK of course).

Thanks for the detailed answer. I contacted my carrier which is EE here in the UK. They said we are running different bands of 5G as compared to the US 5G bands.
And they confirmed that my plan is 5G enabled...

Hi, Thanks for your reply, I contacted them, and Yes, they said we are running different 5G bands here in UK as compared to US 5G bands and your US version supports the bands currently US carriers are providing in the US.
So, it means, when they (EE UK) add more 5G bands in their service like more frequencies of 5G then I can get the benefit of my 5G Snapdragon US version in the UK ???

@ekerbuddyeker I hope you're okay. Could you specify the technicality(s) why it won't work?

it's set up to receive a different set frequencies than are mostly used in Europe as others have said.
Hey. Ignore the incorrect advice from both your carrier and other users here.
Your S21 from the US includes band n78 support even though it isn't advertised.
You just need to enable it and remove the NR whitelist.
You can do it through the service menu (access through Google Dialer).

Yep. We know. I mean do you know which frequency the US version is missing that is required in UK?

The service menu was unfortunately disabled on the US versions many months ago...
*Edit* - To clarify this, I'm sure that the code is probably the same as before, however, when you type it in on the US phones (using Google Phone, of course), the number instantly deletes itself and doesn't allow the menu to open. This was either just before or after launch (I can't remember which one as I had a Note 20 Ultra and exchanged it for this phone just after it released). But just before I did the phone exchange, all of a sudden, I couldn't access that service menu anymore on my Note 20U as it had just been blocked on the US phones. Furthermore, both of my phones were unlocked, and so it doesn't seem to be a carrier dependent thing =(

Not really true. Just add a 2 at the end of the old code, click the first menu option, then 3 dot, back. Click the first option, and again, 3 menu, back. And now you've got the old service menu back.
We still have QPST access to if they ever block that second code

Only if they add the specific US bands, which is as likely as the UK Ministry of Transport regulating that the UK will start driving on the left to be in line with the US, but phasing it in, and starting only with Heavy Goods Vehicles first.
I have a grey import South East Asian variant of this phone. I'm using it in Australia on Optus 5G network and I'm not seeing 5G?
In the SIM card settings it's set to 5G/LTE/3G/2G Auto but I only ever see 4G+ at best.
Do they use different 5G bands in SE Asia compared to Australia? If so is there anyway to get the 5G to work here in Australia?

Maybe you don't have 5G reception there. But there is a new firmware - maybe that will help

Yes, it's definitely in a 5G area as my work colleagues receive 5G with the same SIM. Would this firmware work with my Dual SIM version?
before flashing any firmware have a look at this app, I've not used it but others say it's helped them out.
Samsung Band Selection - Apps on Google Play
This app will help you access hidden network settings for forcing band selection
play.google.com
there's definitely a chance that the bands the phone prefers to use don't exist where you are. you should do some research about what 5G bands that model number supports and about what Optus and Australia in general supports. 5G bands are weirdly named so be careful, hopefully you'll find some overlap.
I am in the United States and I have cricket, I just purchased the dual sim 998B/DS and I am not finding any ATT or AIO CSC for the phone. I am not able to get 5G over here on this phone so far so I am hoping somehow it would help with the cricket CSC. Maybe I am wrong, Cricket used the imei and swore it would work as well as Tmobile, neither sim cards allow 5g so far.
See at >Samsung Galaxy S21 Ultra 5G<.
There are huge differences between 5G bands support for the US and international versions.
So it doesn't surprise me at all that the inter-national model doesn't work in the US broadcasters' 5G bands.
I wasn't actually trying to surprise anyone, just seeing if anyone has a solution?
The problem is not in the phone and there is no way to replace hardware that does not support the US 5G band.
I read somewhere that in some models of Chinese devices it is possible to make a programmatic change in the hidden settings of the phone using a code entered in the phone's keypad. Try it.

The international Variant does not support the needed frequencies for 5G in USA - physically
There is no way to use 5G in US, without the Snapdragon Variant
Thanks
