5G Network Bands - Samsung Galaxy S21 Questions

Hello,
I am looking to buy an unlocked S21 from Samsung Canada store (SM-G991W) and I checked here :
S21 differences that the following 5G bands: n2, n41, n66, n71 are the ones supported by the Candian model so my question is:
Is it possible to change the supported bands? For example, if I travel to a country where the used 5G band is the n28, will the S21 support this band. If so, how please?
Btw, I have seen some users changing Network bands on Samsung devices without root so I want to make sure that it works with the 5G bands especially from someone who have a S21 please?
Here is the link of the short tutorial: Un/Locking LTE Bands on Samsung I am talking about.
Thanks for your help

The SM-G911W had the following technical specifications for mobile network 5G: 2, 5, 25, 41, 66, 71, 260, 261.
Check here for differences of the S21 5G variants:
Samsung Galaxy S21 5G Model Number SM-G991* Differences - TechWalls
There are a lot of model numbers of the Samsung Galaxy S21 5G on the market but all of them start with SM-G991. To find out all the differences, you can check the comparison table below.

AFAIK this is caused by hardware. So no software related "unlocking".

Frequency bands supported?

Is there any way to check exactly which 2G/3G/4G and 5G bands my Android phones support?
I know that GSMArena and frequencycheck.com do have some data, but they may not be always 100% accurate,
especially when there is loots of model made for different markets e.g Samsung Galaxy S20 Ultra 5G:
SM-G988,
SM-G988U
SM-G988U1
SM-G9880
SM-G988B/DS
SM-G988N
SM-G988B

I don't know of a user interface in Android to enumerate the radio frequencies that a device handles.
How about Android Debug Bridge (ADB)?
There is way via modem logs check what bands and carrier aggregation combinations your device support: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/
I have tried collect these modem log data to my cacombos.com website: https://cacombos.com/
Please submit your device modem log to contribute.

S10 Lite & SIM Band frequencies in Japan

Hello, I have a fairly difficult technicaly question regarding the Samsung S10 Lite. I recently purchased the S10 Lite (SM-G770U1 )and I am currently residing in Japan. To my surprise, I have learned that almost all carriers do not support the model that I have (listed above).
I have managed to find one carrier that I think might support the phone, but I am unsure whether the Frequency bands of my model are the ones listed by the carrier.
The bands that are supported in Japan are the 3G Band 1 (2100MHz) or 4G Band 1 (2100MHz) frequency.
Please let me know if these are supported by SM-G770U1 Model. Thank you so much in advance!
Name of the Japanese Carrier with the SIM information (thought it is very limited)

Does anyone know if the tablet will work with TMOBILE 5G SA/NSA under the Band N41 (2.5GHz)?

Hi, the tab S7 plus 5G hold those frequences in 5G = n1 (2100), n28 (700), n41 (2500), n77 (3700), n78 (3500), n79 (4700)
so it should work, that's what i think
If there is SA enabled then it might work but otherwise I think not because this device doesn't support LTE anchor band used in US. To confirm bands support need log from tablet modem: https://mt-tech.fi/en/how-to-get-4g...tions-from-your-android-phone/#Scat_(Qualcomm)

Hi i just asked this in a new thread but after noticed this reply.
Would you mind me asking where you found this information? as i have seen mixed information online about 5g bands.
Also is this the US variant? and are the s7 11 inch 5g model bands the exact same?

Galaxy S7 & S7 Plus 5g Bands Help

I Purchased the note 20 Ultra 5G in USA and shipped it to Australia.
I later found out that the US Note 20 Ultra 5G variant doesnt have band n78, which is the main band of Asutralias best 5g provider, Telstra.
I am wondering if anyone knows conclusively if the s7 5g or s7+ 5g has the n78 band, some websites denote it does, others say it doesnt, but i feel they might be reffing to the LTE version sometime which of course does not have n78 5G band. This is the US variant from Samsung.com website.
Thanks in advance

Same problem....I had the s20 Ultra and it stopped working on Telstra. Got a new s21 in the hope it would be fine and still nothing. Checked my plan with Telstra and they tell me 5g is enabled.... The phone has b78 band but still nothing. Just been a big waste of money

Damn.... I really don't like the Exynos 2100. so laggy in games. looks like I'll just have to sell my Exynos S21 Ultra and get maybe the Xiaomi 11 Ultra or something similar
I recently purchased this model for the snapdragon processor and can confirm that Telstra 5G network does not work. This was also confirmed by Telstra who said it is not a supported model, but in future, it could be allowed. ETA is unknown on this. Disappointing to say the least.

Hey @MAX 404
Previously installed the regular Samsung updates as they came through. I noticed I had a carrier update on my note 9, so manually checked for an update on my S21 ultra.
Carrier is Telstra in Australia. I've attached a screenshot of Software information for reference.
I believe Telstra use n78 band which was blocked on the SM-G9980 model when I initially got the phone.
Hope it helps for those wanting a snapdragon S21 ultra.
