Its MSRP. They show band 30 (which is critical for AT&T) and 5G bands, for a dual sim device.
Anyone know if this is accurate?
G988B is Exynos device and that doesn't support well bands and carrier aggregation combinations used in US.

According to FrequencyCheck Band 30 is not supported. I've purchased a number of devices from MSRP, their device specs aren't always accurate.

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.

does Samsung galaxy S20 -G9810(HK) will support CA in india?

Don't know - free to test but I recommend global variant for Indian market not HK.
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 there a variant that i can root and use on tmobile 5g?
Forget about trying to root Snapdragon versions.
@42o247 forget @roaduardo and his wrong answer.
if you want to root Snapdragon get SM-G9860 for S20+ works like a charm.

there are tons of information about this device. I gave you already the most important information which was SM-G9860. You can easily google SM-G9860 5G T-Mobile. Or search for the supported bands and the bands T-Mobile uses.

i tried that before i even posted but most of the results are for the sm-g9860u and from the how to root guide it seemed like all the variants ending with U were unable to unlock the bootloader or root. i figured i would ask if anyone had a personal opinion or knowledge before wasting more of my time searching. thanks for the response though your thoughts are sincerely appreciated.

These are T-mobile's 5G Bands.
Band n71 (600 MHz)
Band N260 (39 GHz)
Band N261 (28 GHz)
Band n41 (2.5 GHz)
These are the SM-G9880 and SM-G9860 5G Bands.
Bands Sub6
Band N41 (2.5 GHz)
Band N78 (3.5 GHz)
Band N79 (4.5 GHz)
Samsung S20 5G UW Bands
260, 261 mmWave
The device "should work" on Band N41. Also, keep in mind there are different variants of 5G Protocol. Low-Band, Mid-Band and Millimeter Wave. mmWave is the gold standard when speed is the only criteria.
mmWave high-band 5G: T-Mobile, AT&T and Verizon. About 10x faster than LTE with extremely low latency, which means you need to be standing really close to a tower or transmitter to get those speeds. Mid-band 5G: Sprint. About 6x faster than LTE, but with a smaller footprint than low-band. Low-band 5G: T-Mobile/AT&T. About 20 percent faster than 4G LTE.
If I were compelled to utilize 5G, which at this time I'm not, I would consider AT&T. They are the only Service Provider offering mmWave 5G on a Samsung 5G UW Device. Even though it has a Snapdragon SoC, I suspect the bootloader is locked like all of the US Carrier Devices.

yeah you should pass on Samsung in general and get a 8 Pro. But if your decision depends only on 5G I have to say it shouldn't be that important, because 5G isn't that relevant so far, and maybe for the coming 1-2 years. And I'm sure won't keep the device longer then that anyways...
Also 5G caused CORONA VIRUS!!! LOL just kidding,

Even device support n41 ( 2.5 GHz) that doesn't mean it work in T-Mobile/Sprint 5G-network because it require anchor band on 4G. But i don't know much about this Hong Kong variant because haven't got any log from it. If someone have, please share. Here is instruction to get modem log: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Please send log to: https://cacombos.com/contribute
I have some S20 variants supported bands and these combinations in my site: https://cacombos.com/search?key=S20 . I just need more data from these devices to complete listing.
But in USA i recommend buy device in US. Devices from overseas doesn't often support 4G and 5G carrier combinations used in US so you get less speed on network.

A great resource and good to know, thanks! I agree with your suggestion to purchase the device from your Service Provider, that will pretty much guarantee you'll have all Carrier Aggregation utilities and 5G Connectivity Protocols in place. Unfortunately, users want a phone which has everything, no bloatware, unlocked bootloader, universal connectivity, full carrier aggregation and the best SoC. With all the variants from Samsung and varied Service Provider metrics that's not realistic.
I have a few questions you may be qualified to answer. Does the first letter of a band being capitalized or not have significance? Example n71 or N71? Does this represent MHz versus GHz? Secondly, in the example above, both the device and AT&T have a number of matching 4G Bands. Would this indicate the device will be able to anchor to the carrier? Lastly, let's assume a device and the carrier have multiple matching bands. Who or what determines which band will be paired in a specific connection, will the carrier determine this based on location or traffic volume, does the user have the ability switch to a specific bandwidth?

n71 and N71 is same band 600 MHz 5G NR. But in cacombos.com you see different characters like C what means contiguous intra-band CA. Example 3C.
On cacombos.com you can see example combination 2A4-66A4A_n71A2A what means 2-66_71 CA combination. Band 66 is anchor band for n71 5G.
I bought a Galaxy S22 Ultra Model SM-N986UZKAXAA Is there a way to update it to have the n78 5G band?
The hardware doesn't seem to support it.
Some variants do.
Maybe it's firmware...
