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 all,
I'm wondering whether it is possible in some way to unlock additional NR bands on the S20. As far as I understand the Snapdragon 865 chipset, it comes as a fully-fledged 5G mobile platform which can be used in all countries and which supports all possible NR frequencies/bands.
So, it seems to me, that Samsung just locks off the majority of bands in the different models (for example, I got the G9810 and like to use it overall in Europe. However, Samsung only delivers the bands N1 and N78 but not e.g. N28).
Would be great if anybody could give me a hint about this.

I think there is no way to add more bands because these are defined to hardware. But i'm very interested about your model 4G Carrier Aggregation Combinations. These can get from log file: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Could you please share to me this BandInfo file? You can send this to https://cacombos.com/contribute
check out the Samsung Band Selection app on the Play Store. Supposedly, it can unlock hidden bands.
I looked at it but I'm unsure which bands are available to Sprint/ T Mobile in the St. Louis area. I set to Automatic. Playing it safe I guess .
Also when I switch to 5G it doen't show any bands. The S20 + is capable of more 5G bands I hear

Only can disable/enable bands what hardware support. If it doesn't you can't just randomly unlock bands.

Hello to all,
i recently bought the Galaxy S20+ G986N, mine is a korean version!
Now I accidentally read that the 3G/4G and 5G networks are limited! --> I did not know before!
Is it possible to unlock the networks?
Thanks in advance and regards
Daniel
PS:
Is it possible to unlock the Dual Sim version here? Since this is a SingleSim!
Allegedly yes if you bought the phone sans mobile network, pop you sim inside and talk to someone for 10 minutes, on your local network that is, it should reset to a "domestic" flavor of networks... it can be checked via the secret menu *#60# or something like that (google is your friend if not), dough snapdragon has no issue whatsoever with working on any network, the network locked ones and usa specific ones are a different thing, - even those can be made to work.
I was not aware any of the s10 and s20 series come with just a single sim as one slot can be used for sdcard and a sim... Give it a shot, you already bought the phone anyways...
I also just mean the 5g net. I guess only the Sub6 n78 is activated here. The mmwave not at all!
The question is, does it have a software or hardware limitation? If software, which one can I install via odin?

In fact 5G limited not only by software, but by hardware too, every band protocol of 5G requires appropriate specific antenna to be installed in your device. Moreover, you can't flash anything except the firmware designed for N version (no U/U1 whatsoever options) because of boot-loader.
Thanks for your reply.
For mmwave you need hardware, but I guess for Sub6 it's only limited by sw?!?
5g supported bands are limited by hardware.
Korean models only support 5G n78.
Hope this helps

It's possible (4G bands) on some old phones (pre-835 era), but not so much these days though

I thought all Snapdragon processor used devices where u.s. version devices.and that all exynos processor devices where international devices.I want to buy a international device Samsung galaxy s20 plus that I can root and flash different roms and mods on too. Which International Version device would you buy if you wanted to place Round 2 mods onto is there any particular one or just any International device. Because all u.s. versions of the s20 plus cannot be rooted and romed correct. Thanks In advance!!!

The International Snapdragon variants have a better SoC however being in Denmark you won't get some Carrier Features the Exynos variants offer, that's the trade off.

I have the Hong Kong variant on T-mobile. Advantages - Snapdragon SoC, no carrier bloatware, close to pure android, dual sims, unlocked bootloader, price ($745 on eBay). Disadvantages - Warranty repair would be difficult, no 5G yet or carrier aggregation. Highly recommend, my S8, S9 and S10, all Hong Kong variants, never had any problems whatsoever.

You should post a guide on how to unlock the bootloader on the US model. To my knowledge no one has been able to achieve this.

Not to me, I typically download large files on my laptop via WiFi then transfer them to my device. I'm a frequent flyer so I watch movies (torrents) which are typically 2GB. Not sure how long that would take to download on my device via T-mobile but it's not significantly faster than WiFi. When mmWave is widely avaliable Carrier Aggregation will be more valuable but right now High-band 5G is comparable to WiFi file transfer speeds. That's a small inconvenience compared to the benefits the device offers.
@varcor did you change the CSC to see if CA works ?
I'm assuming you're on TGY. I'm also in the USA and think changing to BRI might increase ca bands.

No, my CSC is TGY. I live in Mexico but use T-mobile since they offer free calls and data in collaboration with Mexico's largest telcom Telcel. Even when I'm in the US I don't have CA. I haven't gone to T-mobile to ask if they can configure CA but I doubt they can on the SM-G9860 or SM-G9880 regardless of the CSC. I use a laptop with Wifi for large downloads so it's not a priority. I do get Wifi Calling and VoLTE even in Mexico, YMMV depending on your service provider. Also I've read BRI has some issues so I'm not inclined to make the switch. This thread may give you further insight.

That link is google amped , perhaps you can edit it to make it viewable, thanks.
I was just curious to know if someone had changed their CSC to BRI and if it enabled CA.
I believe the first thing to be gathered is what bands are CA enable on the BRI CSC before even proceeding with anything else.
Also before flashing to attain CA I think one needs to compare tgy and bri CA combos.
Edit. Read that already, mainly non americans discussing attaining 5G on their respective countries.

I have a bootloader unlocked, rooted Galaxy S20 Ultra SM-G9880 (Hong Kong version) that I am using on T-Mobile. However, I had some doubts about how it interacts with the various bands.
The phone does not support some of T-Mobile's LTE bands, and it does not seem to support any of their current 5G bands. Is there any way to change this with CSC changes or any other trickery?
Would AT&T be better for any of this?
When I use the Samsung band selector app, I see that NR B41 is supported. This is the Sprint spectrum that T-Mobile is repurposing, correct? Does that mean additional 5G and LTE coverage once the rollout is complete?
Another user was having problems enabling carrier aggregation. Is there a way of doing this?

You can't change to a US CSC on your device. Some users are reporting 5G works only on SIM2. Carrier Aggregation isn't compatible in the US with the SM-G9880. I have the Hong Kong variant on T-mobile and 4G LTE works fine.

Would you happen to know if our imei works with 5g on t mobile? I just switched last month from att. On att, you would have to call and give an att imei in order for 5g to work and I'm wondering if t mobile is the same way or if it works out of the box with our imei.
Also, I have an SD card and seems like I cannot have a Sim on slot 2 and an SD at the same time, do you happen to know if an esim will get 5g?

That's a question for T-mobile. It's not a question of your IMEI, it's whether or not your device's available 4G and 5G bands are compatible with T-mobile. I don't know what model you have but if it's a US model eSim isn't available on S20 devices. Only Exynos devices have eSim capabilities.

I have the same model that's been on topic... The SM-G9880...
SM-G9880 isn't eSim enabled, only Exynos variants offer this. 5G may work, take it to your local T-mobile store and see if they can set it up. Often times information coming from a CSR over the phone isn't reliable. If it worked with AT&T on SIM 1 T-mobile it MAY work as well however many users have stated it only works on SIM 2. Even though T-mobile's 5G network has a larger coverage area they can't match the speed of AT&T's mmWave network.

If you root the device I suppose it's possible to override an eSim block on the SM-G9880 but I'm not aware of anyone achieving it. The only Snapdragon variant which offers eSim at this time is the Galaxy Fold. I don't understand what the value of eSim is on a Dual SIM device. Even if you travel to a different country it's a simple choice, keep the SD Card in or use both SIM's and rely on internal memory for storage.
Did anyone try using BRI CSC to see if CA works in the USA?
Hi guys i've searched all over the net for a solution and i am starting to think that there is none.
I've bought a Samsung Fold3 5g SM-F926U1 and i think it is an US model. I live in Romania and i can't get 5g signal, only LTE. Tried everything that is normal, reset settings, update internet profile, switched on and off, selected 5G auto and/or GLOBAL.
Nothing works. Do you have any solution? Flash a different rom on it or something?
The phone is single sim, in Romania they sell the dual sim version
Thank you
The F926U supports these 5G bands:
SA/NSA/Sub6/mmWave (2, 5, 25, 41, 66, 71, 260, 261)
What 5G bands does your provider use?

Thanks for the tip. I will probably do the same if there is no other way.
it is possible the software installed on it is not playing nice with the carrier in your region.
for example. In the US, each carrier decides which version of SW update to release to their customer, but if a user brings their own device that was with another carrier hence has a different software version than what is being used for the new carrier... the phone tends to have issues or not be able to update and such.
Other possibility is that the region you are in doesn't use the band that the phone supports (but this might be less likely in my opinion, but I'm no professional nor do I have experience with overseas inter-usability so I may be wrong).
