Unlock all 5G/LTE Bands of unlocked Tmobile Note 20 Ultra 5G phone - Samsung Galaxy Note 20 Ultra Questions & Answers

Hi,
Is there any way to unlock all 5G/LTE bands so that unlocked Tmobile Note 20 Ultra 5G phone can be used on any US carriers including MVNOs fullest?
Below are bands supported by hardware- SM-N986U:-
GSM Mhz bandQuad-Band 850/900/1800/1900Primary 2G networkGSM 850/900/1800/1900Primary 3G networkUMTS 850/900/1700/1900/2100Primary 4G networkLTE Cat20 (1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 18, 19, 20, 25, 26, 28, 29, 30, 66)

VoLTEPrimary 5G networkSA/NSA/Sub6 (2, 5, 41, 66, 71)
mmWave (260, 261)
but with Tmobile ROM only following bands are available:-

You could try this, it's meant for U1 devices so not all options will be available but its worth a try

Try the official samsung website. Although still dubious information wise. Then toggle between models.
www.samsung.com/us/business/support/owners/product/galaxy-note20-ultra-5g-t-mobile/

So what I have seen is that the SD Version theoretically has all bands. But they are somehow software disabled.
By downloading google dialer... Then typing *#*#27663368378#*#*
From here go to option 5... Then to option 1.
From here tap on option 8.
This will show all bands that the x55 modem is capable of. But this setting doesn't stay set. This the furthest I've gotten to seeing all the bands.
However following this link will show how to get all USA bands:

SD doesn't have all the same bands. The sm-n9860 and sm-n986U differ bands and not "unlockable" via keypad method . I know because I've owned both.

So changing a few settings will make all bands that the x55 modem can support but once you exit the settings and return... They revert back to to the original bands that are available in the USA... In this picture... You can see the suppo

I can keep the LTE ones on and can verify in the samsung band selection app but the NR bands do not stay on...

Oh I see.
What I was trying to say is that my sm-n9860 didn't show some of those LTE bands listed in your screenshot when I owned one. Example LTE bands, 66 and 71 for starters. So this method won't work to " open up " bands for devices that don't have those bands in the first instance.

However it's been confirmed that if you follow the link... That will open up the LTE bands. But not the NR bands. I I will say I have not had a carrier device but I do have the USA unlocked. Didn't know it was that vastly different

I have Tmobile device which I unlocked.
For me , it opened up NR Bands.
Out of box, i only had NR B41, NR B71, NR B260, NR B261.
After opening up, i now have NR B2, NR B5, NR B41, NR B66, NR B71, NR B260, NR B261. ( opened bands in green)

Interesting.

It also opened up all WCDMA, LTE bands too.
So, i can now use my phone on Verizon without any issues.

LTE Bands for International Version

I've been trying to find the LTE bands for the International/European version of the S6/edge for a couple weeks now but have had no luck with any sites I trust. I was able to come across this site: http://pdadb.net/index.php?m=specs&...g925f_galaxy_s6_edge_lte-a_128gb_samsung_zero
Does anyone know how accurate this site is or know of where I might be able to find trustworthy specs?
Also interested in this. I might get an international version, but want to know if it will work here on the US on the AT&T network

Interested as well, if the international version supports ATT Lte that would be awesome

It means the phone(s) should work on both AT&T and T-Mobile. AT&T uses bands 2, 4, and 17. T-Mobile uses 2, 4, and 12. The International version supposedly supports 1, 2, 3, 4, 5, 7, 8, 18, 19, 20, 26.

Sorry for stating the obvious, but no support for band 17 and 12 on the international version then? What does this mean in teems of coverage and speed?

Where there are cell towers that are broadcasting using bands 12 or 17, you will not be able to get LTE coverage, but you will be able to get coverages for towers broadcasting on bands 2 and 4. Your real world coverage will depend on where you live and how each carrier has decided to configure their networks, but you will be able to have LTE for both.
[edit] Both 12 and 17 are 700mhz frequencies, which means that indoor coverage will not be as good if you don't have those frequencies. So that's a trade-off you might want to think about before going with the International version. Though for the most part, many people will have access to a wi-fi network while at work and at home, which I assume would be where most people would be for most of their day.
From what I've been reading, WiFi calling/texting features only work if you buy a T-Mobile specific device. Any other phones used on T-Mobile won't work with WiFi calling/texting features. That alone is the reason I would not buy an international phone and use it on T-Mobile.

Hi guys,
I have noticed that the verison I can purchase in France is the SM-G920FZ-02. Is it the same thing as the SM-G920F ?
I am unable to find the LTE bands for this version...
If it is not the case, I guess i could just get the SM-G920F from another country ? I've seen it on the UK version of the Samsung website.
I'm travelling a lot between Europe and the US so it's one of my main concerns but apparently Samsung doesn't give too much information on this yet!
FCC filing show the international model will support LTE band 2, 4, 12 among others: https://apps.fcc.gov/oetcf/eas/repo...ame=N&application_id=794688&fcc_id=A3LSMG920F
Based on the info so far in this thread , it would seem like a safe conclusion that the 920F international version would indeed work fine on the AT&T LTE network
So does it support 12 and 17?? I'd be interested in getting the international for ATT. Just not sure what will and won't work

Band 17 is a subband of 12 (12 is the larger scope that includes 17 in it). The S6 920F support band 12 so it should work on AT&T just fine.
Bands 4 and 2 which are also used by AT&T are also supported according to the FCC documents so i assume the international model 920F should work just fine.
I can't be sure the same about other 920X models out there.
Does anyone know the difference between the 920F and the 9200?

Samsung I9200 is the Galaxy Mega. Is that what you're referring to?
I realised that there are commonly 2 available international versions, SM-920F (European?) and SM-920I (Rest of the world?). Wondering if anyone has the LTE specifications for the SM-920I version?
Edit (4 April): Found the answer to my own question at the Singapore Samsung website (under Specifications). So LTE Bands 1,2,3,5,7,8,12,17,18,19,26,28. No Band 4 though. I'm guessing that would greatly degrade the LTE experience with AT&T and T-Mobile?
4G+ LTE Cat 6 up to 300Mbps, VoLTE, 4G+ LTE FDD [Band 1 (2100MHz)/ Band 2 (1900MHz)/ Band 3 (1800MHz)/ Band 5 (850MHz)/ Band 7 (2600MHz)/ Band 8 (900MHz)/ Band 12 (700MHz)/ Band 17 (700MHz)/ Band 18 (800MHz)/ Band 19 (800MHz)/ Band 26 (800MHz) Band 28 (700MHz)], 4G+ LTE TDD [Band 40 (2300MHz)]

Edit (8 April): Interestingly, the Australian Samsung website for the same model (SM-G920I) shows that Band 4 is supported. I'm totally confused now as to whether this particular model supports LTE Band 4.

[dismiss] Those considering Dual-Sim H990DS better get H990N if you're in USA

Those considering to use the LG V20 Dual Sim in the US should pick the H990N instead the H990DS because is the only Dual-Sim version to support AT&T's LTE bands 17, and Sprints band 26, notwithstanding the DS is faster and both version support T-Mobile bands, those looking to use the 2nd sim as carrier backup service likely will pick AT&T or Sprint as secondary or main line.
The original post was based on information available from 3rd about H990DS and H990N, none indicated the N990DS to support LTE B17, while some users reported it actually support that band, information confirmed from LG's Taiwan site confirms LG V20 N990DS actually supports LTE B17, accordingly this post is unfounded and moot.
Moderators, please close thread.

Hate to burst your bubble but you are incorrect. I have the DS with both tmo and att. Grtting band 17 just fine.
According to both these sources H990DS is missing band 17. H990N seems perfect for me, it has band 17 (in addition for 2&4 for AT&T), also has band 1 that the US996 is missing which I need for the occasional visit to Japan.

Seems the H990N the best deal for Travelers.
According to LG's Taiwan website, the H990DS supports bands 1 and 17 but not 26. It's highly unlikely LG would release a phone in Taiwan that didn't work in Japan. I can read Chinese by the way.
Most if not all android phones will work in japan, 4G is not always suitable, but 3G 2100 is available and japan supports it.
LTE B17 is ONLY OPTION IN: BAHAMAS, CAYMAN IS, ANGUILLA, and JAMAICA. or 3G
Others Networks using B17 are in markets where you have at least one alternative (available on both V20s) as USA (AT&T) where you can go on T-MO where no AT&T B17.
LTE B26 only user yet is Sprint (acc Wikipedia) also only in few areas, where you also have alternatives from other networks.

its rigth, no need to speak chinese http://www.lg.com/tw/smart-phones/lg-LGH990ds
Thanks for posting the TW site. Im really happy if the H990DS supports band 17 according to the site. Not sure if all other sites are quoting frequency check, as every other site I googled quoted H990DS specs as without band 17.
If anyone has an H990DS, would you be able to check the following?
Enter Engineering mode:
On my V10 H960A, code is *#546368#*960# (Not sure if this is the right code for V20, may need to replace 960 with 990)

You should be in the "LTE information" page. It should show what LTE band you're connected to. If anyone can verify and post a screenshot and band 17 I'd greatly appreciate it.
Thanks in advance.

Hi all! I've been a lurker for a while now and have been appreciative of all of the progress that has been made with flashing firmware on the Galaxy S8+ in order to take say a Verizon phone and make it completely usable on T-Mobile without the bloatware from Verizon (or from any carrier).
I'm posting today because I was hoping to learn a little more on how to determine which LTE Bands have been unlocked after flashing firmware on a Galaxy S8+ that was originally a Verizon device that is now being used on T-Mobile.
This link was helpful: https://forum.xda-developers.com/galaxy-s8+/how-to/how-to-verify-t-mobile-services-wifi-t3612996
Was wondering if there was any other way to make sure that the T-Mobile bands that needed to be unlocked were unlocked as required with the flashing of firmware. The firmware was acquired from sammobile.com with these details:
Download the firmware for the SM-G955U1 with product code USC from USA. This firmware has version number PDA G955U1UEU1AQDC and CSC G955U1OYM1AQDC. The operating system of this firmware is Android 7, with build date Thu, 27 Apr 2017 10:19:22 +0000. Security patch date is 2017-04-01, with changelist 11247461.

After dialing: *#2263#
I do see here that the following band elements are present:
GSM: 850, 900, 1800, 1900
WCDMA: 1, 2, 4, 5,
TDS: A, F
LTE: 1, 2, 3, 4, 5, 7, 8, 12, 13, 18, 19 20, 25, 26, 28, 39, 40, 41, 66, 252, 255
Does this mean that these are all enabled and available for the network to choose from?

Ah, one thing I forgot to add was that I had flashed the Verizon phone with my tmobile simcard present in the phone. It went through a process where it configured the phone based on the simcard present. Not sure if this is normal when an unlocked Galaxy S8+ is activated, but this behavior was unique because I did not experience this when I inserted the tmobile simcard into the verizon phone prior to flashing the firmware.
I know the US unlocked version from Samsung has the band 17 band, Att still uses band 17 in my area where I work and when I had the ATT version, I was always missing text messages and when i sent them my wife would only get half of them, so when i did some research looks like ATT did away with the Band 17 in ATT version of the S8+, so i went back to my Note 5 that`s has the band 17 in it and problem went away, so I have the US version unlocked coming tomorrow so well see if it works any better than the S8+ ATT version

Is there a difference between the "U" version and "U1" version... I usually buy the international "F" version but unfortunately this year it wasn't possible... So anyway it's supposed to be unlocked but don't know if it can be rooted
Galaxy S7 edge
Strange that band 17 is not enabled on the USA unlocked firmware.
Band 12 on phones allows you to use band 17 on AT&T. Band 17 is 700 kHz block B and C, band 12 is 700mhz blocks A, B, and C.

AT&T's started to use Band 12 to connect both B17 and B12 devices from their towers in order to help roaming functionality between Tmobile and AT&T.
The Compare page at GSMarena website shows the bands of most versions of most common smartphones. B&H Photo does too. Note: Occasionally it is necessary to search for the phone version using its code, e.g. G955U, rather than its common name, to find it, but often the common name and version name (e.g. Sprint) suffice.
Also, I noticed that a version for the carrier called US Cellular reportedly had the same bands as an unlocked phone, at least according to gsmarena. Which means that version would be well suited for use with any of the major carriers.
All the us phones have and can use any of the bands it lists in specs. May need to flash a different carrier firmware to enable possible disabled bands. But I haven't seen any disabled. At least ony Xfinity mobile on Verizon towers

Is it possible to change Bands (LTE & 5G) on SM-N9860 For Rogers Wireless in Canada?

Is it possible to change Bands (LTE & 5G) on SM-N9860 For Rogers Wireless in Canada?
I had a thought:
Currently, the Samsung Galaxy Note 20 Ultra 5G Dual Sim (SM-N9860, Snapdragon) 12GB Ram 512GB has the following LTE & 5G Bands:
4G FDD-LTE:
B1(2100),B2(1900),B3(1800),B4(AWS),B5(850),B7(2600),B8(900),B12(700),B13(700), B18(800),B19(800),B20(800),B25(1900),B26(850),B28(700)
4G TDD-LTE:
B34(2010),B38(2600),B39(1900),B40(2300),B41(2500)
5G Sub-6 FDD:
N1(2100) / 5G Sub-6 TDD: N78(3500),N79(4500)
Now, I am with Rogers, which requires the following bands:
LTE Bands:
700 MHz Lower A/B/C: 12/17/13
850 MHz CLR: 5
1700/2100 MHz AWS: 4
2600 MHz IMT-E: 7
1900 MHz PCS: 2
While SM-N9860 supports all but one - Band 17 LTE bands - the phone should work almost flawlessly with Rogers in terms of LTE. However, when it comes to 5G, it is a complete different story.
5G Bands:
2600 MHz IMT-E: n38
600 MHz DD n71
The Canadian (similar to the US) variant of Note 20 Ultra 5G supports the following band:
LTE Bands:
B1, B2, B3, B4, B5, B7, B8, B12, B13, B17, B18, B19, B20, B25, B29, B30, B66, B71
5G Bands:
n41, n66, n71
Questions:
1. Since both are based on the Qualcomm SM8250 Snapdragon 865+, is there a way to change the LTE & 5G bands?
2. Is it hard-coded into the firmware of the 5G modem that is incorporated with the Snapdragon 865+, which makes it impossible?
3. Does that fact that SM-N9860 has a unlocked bootloader and it is rootable, would this help change the bands or matters of the bootloader / root does not have anything to do with the frequencies / bands?
4. If the matters pertaining to unlocked bootloader/rootable , should this question be asked in the thread that Dr. Ketan discusses, with regards to the rooting process?
5. Only reason that I ask for all this is: recalling from memory from earlier days of Note(s) 1 thru 4 - rooting, installing custom rom (thru odin), etc. - I remember coming across a "modem" specific file that gets flashed by odin. Is that still true these days with the newer Note models or it is different?
6. I understand that Qualcomm supplies the specific modem chipset, with regards to 5G - would any of their development tools supplied by Qualcomm can help with changing the bands?
Thanks, just wanted to know.
Thanks.
It seems no one has replied.
Is it really that hard to change the LTE & 5G bands on the SM-N9860 model, given that it uses the Qualcomm SM8250 Snapdragon 865+ chipset (which I am presuming it has the 5G embedded modem)?

5g wouldn't work on N9860 in US/Canada. But some users reported its working in UK.
By the way can you please tell me do you have n9860 hong kong variant? And which CSC it has?

Hi, sorry for the delay.
How do you find out the CSC that is installed on this phone?
My baseband version indicates: N9860ZCU1ATH2 - does that help?

Years ago we used to be able to play around with enabling bands using something called QPST ( i think, its been awhile) but i have no idea if it will work on new devices.
Id suggest tailoring your search to that and see what state its in.

Yes because you have N9860 Hong Kong variant.
These are the bands available for sm_n986u1
You pick the lte bands that you want to use... Att/tmoble may have to check the gsm bands for calls.

Depends on carrier... But I want to say it's the n261 and 260 and anything above 28... I could be wrong... I'm not in a 5g area... But I checked the vZw bands... Idk for other carriers
I think Rogers, Telus and Bell are all using band 66 for their 5G.

Thank You very much sir.
Im banging my head for such answer.

So basically; only at&t gives me 5g with n5.
That too : low end 5g
I have to wait for august then(next note).
Don't change CSC. If you will do, then it will goes brick phone.

I think international variants doesn't work with US 5G because these doesn't support combinations used in US and also 5G may not be enabled in your network. On 5G the device must support EN_DC combination used network. In cacombos.com you can check Carrier Aggregation and EN_DC combination support of devices.
