Enabling Carrier Aggregation - Samsung Galaxy Note 20 Ultra Questions & Answers

I received a Note 20 Ultra (Snapdragon) from a relative residing in the US. I am currently in Malaysia, the Exynos region. If I am not mistaken, the 4G+ here uses a combination of band 3 and 7.
On my note 8 device, using my simcard, my mobile connection would show 4G+ in certain areas and 4G in the outskirts. On the note 20 (Snapdragon) it remains on LTE and never LTE+ / LTE-A.
Would it be possible for me to change my csc from XAA (US) to XME (Malaysia)? If so how?
Or is there a way for me to force the carrier aggregation to occur?

I don't think you can change CSC from American region to non American. Not sure much can be done to enable CA

Exactly. Same as me using my HK version in the USA. No CA, I can't change csc to any usa devices.
What you could do is compare CA combos for all USA devices and see which one closely matches your region and then take it from there.

I think this hardware doesn't have defined Carrier Aggregation combinations used outside from US. Here is listed some supported Carrier Aggregation combinations here if this is same model what you have: https://cacombos.com/device/SM-G988U . You can contribute to webpage cacombo.com/contribute using scat logging method to provide more logs to complete list so then we know.
I think you can change CSC because Qualcomm vs Exynos - complete different device.

Qualcomm version does not support Band 3 (LTE). Only Exynos version supports it.

Can't connect to 5G network

Hello everyone
Just got my hands on the Galaxy A90 5G from south korea SM-A908N KTC. I live in kuwait city got the 5G internet package from Viva telecom but can't seem to connect to the 5G network shows only LTE+ where ever i go even close to a 5G node. Checked our supported frequency band the phone supports it. Noticed in the settings there is a KT twophone service and when starting the phone 5G KT logo appears. My guess it's locked to KT telecom network.
So far only 3 firmwares available for this phone china, korea UK. Can i change the firmware to another region like UK BTU change the CSC file and check if it work?
Thank you and sorry if this thread is not suppose to be posted here i have low posts

Hi, I have the same issue, have u managed to solve this issue, did u manage to switch the korean version with UK version

Looking for Dual sim version don’t care about speed much or 5G

Hi,
I'm not sure which model to go for to be honest. I'm aware the Hong Kong snapdragon sm-n9860 is better than the sm-n986b or sm-n985F. I'm not a gamer but battery life matters to me. I also need a model with most USA bands for TMobile and to have Volte working. I'm aware band 71 and 66 is not available on the HK version nor is UMTS 3G band 4 - is the latter important ? In the past I'd normally cross reference LTE bands for imported devices. So long as they had LTE bands 2,4 and 12 and maybe 66 they worked for me just fine in central Florida.
So which if any would be advised?

Enable LTE+/4G+ in Europe for US model?

Hi,
I bought my pixel 4a in the USA last month and now that I am back to europe, I noticed that carrier aggregation is not working.
I found on google that on previous pixels, carrier aggregation only works for the region on where you bough the phone... so now, I am stuck with single band connection.
Is there any way to force enable LTE+/4G+ carrier aggregation / CA2 in Europe for an USA, unlocked model?
I don't have root... but I would root it if that means enabling that feature globally.
in Germany LTE+ is working out of the box. no root

Do you have the USA model and not the one released for EU?
And are you running Android 11?
I tried it in Portugal, UK, Spain and France on Vodafone and I couldn't get any 4G+ connectivity.
In the US I had no issues with LTE+ at all, only when I came back to europe.
eu model, android 11 stock

Resting Wi_Fi, mobile & Bluetooth...............or factory reset doesn't work I assume.
Maybe try this:

I was hoping more for some mod perhaps.
I have checked that my phone is only connecting to one band, without aggregation.
It worked fine in the usa, but not in europe, so most likely, they lock it on the oem.
The bands are supported. I have B1,B3,B7,B20 available on my network, and they are all supported individually, but not aggregated.
It does look like the North American model is the G025J, and the European model is the G025N.
I do wonder if getting carrier aggregation working might require some special registration with the carrier though.
It doesn't require carrier registration. I have 3 sims and they all do 4g+ on my old galaxy note 8.
Pixel 3 had the same issue. They block carrier aggregation outside the region on where you bought the product, at the OEM level.
Maybe some dev knows how to unlock it on the software. I've see this for other brands.

5g Bands on Qualcomm X55 modem

I'm curious, since the iphone 12 series is in stores today, it seems that the iphone is using the X55 Qualcomm modem. If I understand correctly, that's the same modem that the Snapdragon Note 20 ultra uses? If so, how come the iphone 12 has so many 5g bands, and the Note 20 ultra is so limited by region? If it's the same modem, why the difference?
If the modems are different, then please ignore my question
What I have noticed is that using the *#272*imei# method and changing it to DSH... I get the exact same amount with the sm-986u1...

This is on the 9860 model?
I'm still curious why apple uses the same modem and has pretty much all worldwide 5g bands covered, and the 9860 has a paltry 3 bands, especially when they're the same modems

I've the US unlocked sm-n986u1... And I'm not sure either. After I changed my csc to DSH... I noticed I had all these.

Cool, although I'm referring specifically to the 9860 model. Assuming all snapdragon units have the same X55 modem, I don't understand why they don't have the same 5g bands, when Apple has clearly shown that the modem is capable of ALL major 5g bands. Does Samsung specifically gimp the modem?

All the units do have the x55 modem and I am not sure why all the bands aren't available for roaming either. The available bands are controlled by the service mode built into the firmware, then further defined by the CSC. I know here in the US, the CSC controls more than just the 5G band availability as well. I have noticed when using t-mobile while on Verizon CSC, SA 5G won't register any service bars in the corner icon. Also band 41 5g, although enabled, won't connect. And then when using Verizon on Tmobile CSC, 5G n5 won't connect even with DSS and n5 NSA enabled.
It looks like architecture in iPhone is one worldwide firmware that just enables all bands and then available services are further changed by the carrier services from the installed Sim.
I followed this user's notes and I think this did the trick.

After going through that thread, doesn't seem like enabling all bands is possible on the 9860.

Question TGY or BRI for use on O2UK S9080?

Hey guys
Long time since I've posted on here!
I've just upgraded from my trusty 8GB/512GB Note9 N960F/DS to a 12GB/512GB S22 Ultra S9080/DS (SD) on TGY (from techinthebasket).
The phone is currently on TGY CSC but I'm wondering if anyone knows whether BRI would be better for use in the UK, specifically on O2UK?
I can see 5G is enabled, and there is 5G in my area (my wife can get it on her iPhone 12 Pro on Sky, which is hosted by O2) but I can't seem to pick up 5G on my S22. I know the 9080 only has the N78 band for O2 so maybe that's the issue - if there's only the lower band 5G in my area...
Just wondering if anyone has any experience regarding TGY vs BRI in the UK?
Thanks

I live in Sweden and the net configuration in Sweden and the UK are all almost the same. The TGY or BRI are the same phone just different SW customization, but you will not notice any difference at all.
The 4G support is very good but not 5G, the 5G band support is limited.
If you want to buy a better model, look for "SM-S908E" model. You can find it from Etoren https://eu.etoren.com/products/sams...ual-sim-sm-s908e-256gb-phantom-white-12gb-ram
I don't recommend BRI (Taiwan) or TGY (Hong Kong) if you want to take advantage of 5G. Also the SM-S908E has e-Sim in addition.

Unfortunately the only option for 5G in the UK is with a Exynos variant. Even though your device reflects 5G is enabled and it has the corresponding 5G Band, it's not going to connect. Snapdragon is a much better choice even though you'll sacrifice 5G and Carrier Aggregation and of the 3 SM-9080 variants Hong Kong TGY is your best option.

Thanks for your replies guys, I really appreciate it!
Can I ask, Carrier Aggregation, that's 4G+ isn't it? If so, it's getting 4G+ OK - did a few speed tests earlier and was getting 117Mbs download speeds... Does that should about right for CA? (It's faster than I saw with the Note9 on 4G+ on the same network anyway)

No, Carrier Aggregation is different than 4G+ but if you're getting 117 MBs that's enough for most situations, right? Carrier aggregation is used in LTE-Advanced in order to increase the bandwidth, and thereby increase the bitrate. I can't see rolling the dice on a Exynos variant just to have 5G. And it is a roll of the dice. Samsung's Quality Control is asleep at the wheel.
Something many don't realize, wafer yeild in Samsung's Foundries for the Exynos SoC was a dreadful 30% but it's Snapdragon yeild wasn't much better at 35%. If I were to consider an S22 Ultra it would be after Qualcomm moved it's production to TSMC's Taiwan Foundry in June or July. That will mark Qualcomm's next gen chipset. But even then problems could still nag the device since the marriage between Android 12 and OneUI 4.1 has to date been a messy affair.
I imported a Samsung Galaxy Note²⁰ Ultra from Hong Kong to use on the UK Network.
It was a TGY variant and worked flawlessly.

I think I read a post from you on the same subject on the Samsung forums before I picked up this phone! That's actually the reason I thought I'd go ahead and get a TGY one!
Hi.
Yes I've discussed this on the Samsung Eu forums too.
Just an update in case anyone is interested - I did a speed test (OOKLA Speedtest) comparison via the browser on both my S9080 TGY (12GB/512GB) showing 4G+ on O2UK and my wife's iPhone 12 Pro showing 5G on Sky (runs on the O2UK network) from the same location last night.
My phone got a maximum of 145.7mbs download on 4G+, her iPhone hit a maximum of 53mbs on 5G in the same location. Of course, they could have been connected to different cell towers etc.
The Hong Kong TGY variant is the closest you'll find to a pure android experience on a Samsung device. Less bloatware, best overall network connectivity with one exception. Samsung should modify it's 5G capabilities so it will work on as many networks as possible. Another improvement would allow system apps to be removed or at least disabled, which will likely never happen. Those two modifications would be a huge step forward.

Samsung do this on purpose to cripple devices and stop people from different regions buying the same product. Similarly with their warranties, its only valid and recognized for the country that the device was intended for. A pure anti consumer move by Samsung. Opposite of the evil Apple, whereby their iPhones don't have bands or CA crippled nor do they deny warranty for customers of other regions.
Just a quick update on this, I've just 'upgraded' my O2UK SIM only tariff to the same 150GB deal but told them my device is 5G enabled this time (I was on a Note9 previously). Anyway, tariff change is completed and I now have 5G (Can also see that HD Voice over 4G is active too)
