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.

What model Samsung S20+ you have? From modem logs you could export some data what your phone support: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices

Is it possible? I'm with MetroPCS and get about 80% of their frequencies but I'm short a few bands. Anyone on the same boat as me?

I'm with T-Mobile and the phone works great with no band issues-even better than my S7 edge Tmo.

I know MetroPCS uses their network. Have you done the frequency check to see if you're getting all their bands, for t mobile I mean? I have attached the bands that the mate supports on Metro but would like to enable the ones that aren't.

I don't think the Mate phone (or any honor 7x version) have the hardware capabilities for band 66 or 71. If the phone was exclusively for T-Mobile, I bet Huawei probably equipped at least their flagships with them. Below you can see all the supported bands from all the Honor 7x versions.

For me, even if the phone had either band 66 or 71 dunno if T-Mobile have deployed these frequencies where I live. I either get band 4 or 12 and is incredible fast (100 Mbps download).
ugh i totally want to know how to unlock all those bands
This phone becomes useless when you travel to Europe especially with LTE as major bands used in Europe aren't supported on US models.
this is very frustrating.
Can anyone else check theirs and see. I feel kind of Jipped...I bought this phone in full from Verizon and now I check the bands to find out it may not support all the 5G bands. I have tmbile, Sprint, and Verizon 5g in my city and I intended on using it. Yes I have all 3 phone carriers.
what app did you use to see what the bands are?
I have same problem the 5G doesn't show how I can fix it ????
I think that band menu changes based on sim card inserted. Try with different sim card which uses that band

It is discussed in the following thread
https://forum.xda-developers.com/galaxy-s20/help/samsung-band-lock-exynos-t4071125
Not sure if anyone experienced this. I bought my S20+ 5G in Sweden (SM-G986B/DS). Recently I'm traveling in China and I noticed that, even there's 5G coverage and i have a sim card which support 5G and i have turned the 5G switch on. I still cannot get 5G signal on my mobile.
I did some search and my carrier is using N78 and SM-G986B/DS supports N1 (2100), N3 (1800), N5 (850), N7 (2600), N8 (900), N28 (700) N40 (2300), N77 (3700), N78 (3500)....So there should not be a problem for my mobile to pick up the signal.
However, a S20+ China/HK version (supports 5G bands N41(2500),N78(3500),N79(4500)) can pick up the 5G signal with same sim card.
So i start suspecting actually there's a lock which preventing my mobile to pick up 5G signal. I read some report that some China version of 5G mobile, such as 1+8 china version or Xiaomi 10, also cannot pick up 5g signal in Europe, even they share the same band...
And that's really getting annoying... Is there a lock? It's a hardware lock or software lock?
In Samsung phone there is Carrier Policy limit bands, features etc per carrier like other devices. I have instruction how you could check supported bands, carrier aggregation and 5G support connected-network with Samsung devices: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices . Without modem log hard to say.
S20+ China/HK-version: https://cacombos.com/device?model=SM-G9860 works at least in China Mobile 5G-network.
Based on your observation of the carrier bands, I'd say the mobile providers in China are using using either N41(2500) or N79(4500) for 5G. Checking the list of bands used by country on Wiki, China Mobile is using n41 (and maybe n79 as well), China Telecom is using N78 and China Unicom is also using N78.
Which mobile company are you using?

It's China Unicom and it's N78. According to the Samsung website, N78 is supported by SM-G986B as well. That's why i'm confused.

Thanks, will try to have a look. and it sounds like even the mobile supports the bands but it's still cannot pick up the signal because the carrier is limited?

This could be possible situation. If you like to get modem log from your device there can see if it support 5G in used network. That is only way. Here is instruction: https://mt-tech.fi/en/how-to-get-4g...tions-from-your-android-phone/#Exynos_devices .
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

Many thanks. Of course it helps...is there's a possibility to unlock the other frequencies which aren't limited by hardware?

It's possible (4G bands) on some old phones (pre-835 era), but not so much these days though
Thanks for your reply. Not so much means, currently no possibility?
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.

I know that some people were trying to enable eSIM on rooted Snapdragon S20 Ultra devices. Did anything ever happen with that?

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?
