Has anyone found a way to unlock all the 5G bands that the SD 888 supports? I tried flashing the 9 pro modem.img but the phone didn't like it.

I'm interested if you ever do figure this out. Service on T-mobile USA is lackluster.
What I did was this:
Download 5G LTE Switcher from the Play Store. Click 5G booster. Choose NR/LTE/GSM/WCDMA under Set preferred network type.

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

I think it is QuickShortcutMaker on google play
It is discussed in the following thread

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.

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.
Best

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
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?
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).
