Question SM-S908B/DS Enable all bands like US based model? - Samsung Galaxy S22 Ultra

Been here about 5 years at XDA, mostly just a lurker from time to time. I found it very interesting about enabling additional base for the US bands S22.
I bought the UK version at launch, wanted the dual SIM and eSIM as well, as I travel often around Asia and previous dual SIM models were extremely handy.
Here in Japan, 5G is very strong, hitting 900+Mbps when I hit a band that my phone supports, however the bands allocated for 5G in Japan are the 3.7 GHz band (n77, n78), the 4.5 GHz band (n79), and the 28 GHz band (n257). n77, n78, n79 and n257 (NTT Docomo).
The UK model supports 1, 2, 3, 5, 7, 8, 12, 20, 25, 28, 38, 40, 41, 66, 75, 77, 78- so I am missing the n79, and n257 which has the best coverage here in Japan.
I would appreciate any feedback you may have, I have tried the US model instructions in the other posts, however I can't get into that service menu dialing the short code.
Many thank in advance. Wes

I'm on S9080 and would love to know as well...

Thanks for the help in advance.:good:

No a unlocked version of the regular OnePlus 7 pro will not work with Sprint...the Sprint variant has 5G...the unlocked version does not...it's kind of stupid and complicated but the only reason Sprint has a OP7Pro is because it's 5G

Thank you for your help. Do you know what phone service it will work on?:good:
Anything but Sprint...I hear it will work So-So on Verizon. Internationally it should work with most carriers.
I currently have an unlocked model on Verizon and it seems to work ok. Had some initial issues with making and receiving calls along with sending texts that took Verizon about 3 days to resolve but outside of that it hasn't been too bad.
Thanks for all your help everyone. Looks like I won't be going with OnePlus 7 Pro.
i have a oneplus 7 pro 5g unlocked from oneplus, and its on sprint, no problems whats so ever, even had it when we went for a 2 day trip to cali, played with the 5g and its fast, but to be honest not that much faster than lte, imo, but still noticably faster non the less

In most markets, at the moment, It would appear sprint is just calling their 2.5GHz, Band 41 LTE as 5G. They are doing some backend stuff with 40-60MHz channels and adjustable sub-carrier frequencies for 5G NR, however, at the moment you won't be seeing any huge improvements as theyre still using their 20 MHz channels with simultaneous connections and MIMO.

Question Unlock frequency bands

I rushed to buy this phone and bought it from Amazon where they said the phone shipped from Hong Kong. I am in the USA and use AT&T. Unfortunately I don't get any 5G signal, even though it's included in my service and the SIM card is 5G capable along with the IMEI being registered with AT&T. Besides 5G not working, the 4G coverage is super slow and I was thinking it was probably because the phone itself doesn't cover sufficient bands available in the USA because my last ROG Phone 2 was super fast in every way. Does anyone know how to unlock the bands for 5G or at least more 4G LTE bands please?!? I really can't stand these speeds
Your carrier would have to add them to the service. The bands you have are set by the hardware. You can't unlock them.
it is tied to your hardware. Youre screwed.. but please dont tell me you paid the premium on the phone just because its was on amazon? You could have gotten the same glorified tablet for 600-700 elsewhere

No I bought the cheaper version (not the ultimate) but with the 16GB RAM. I guess this will just be a project phone
I guess lesson learned! Just sell it then buy the global one.

Who is going to buy it? Now that the proper local versions have released, the resale on a used foreign version is going to be about $200 (unless you pay shipping back to the origin country), meaning you are still around $800 short of buying the same phone.

Yesterday I noticed I had 5g service on my 16gb 256 version. I am also with att. I was surprised to see the icon so I checked the band. It was on band 2 which was previously a lte band in my area. The speeds were the same so I dunnno if it's really 5g or not. Mine is the global one direct from Asus

The global version from Asus has similar bands to the US version. The ones from Hong Kong are Tencent devices, which do not.

Interesting. I'm on AT&T with a 5g plan and sim, and I have yet to see the 5g icon. After spending some time with AT&T support verifying my IMEI etc, I still have had no luck and 5g is definitely active in my area. I have also purchased the phone direct from the US Asus store.
Do you mind sharing your APN settings?

Thanks for these. I'm going to try adding the settings that you used under bearer and see if it changes anything on my phone. I won't be able to try until later but will let you know.
The samsung devices list GID under MVNO and 53FF under value but if I do that on my phone the APN vanishes.
Hopefully Bmayne responds with their setup too since I have the same device.
Billy, thanks for asking about the APN. I didn't think to look at that. Apparently it's a new APN I haven't seen before. Here it is.

Question Network Bands

If i bought a snapdragon version of the S22 ultra from Hongkong or US, will its network bands work in middle eastern countries like Lebanon? how can i check on that?
Also I found this model of the phone SM-R908N and wonder if it could work on the network bands of Lebanon. Any thoughts on this issue I'd really appreciate it.
Oh, one more thing, will i encounter any firmware-related problems too? considering the different firmware models.
Easy to check....go to Alpha, see devices they sell, check specs

TDD LTE Band: B38
UMTS Bands: 1, 3, 8
LTE CA UL Bands: B7+B7, B38+B38

So s22 ultra should work as it supports Band7 and Band 38 as Alpha provides, if no special locks at network, your s22 ultra shoulbe fine (max download speed are unknow)

Question Best Firmware for USA (G996b)

I'm looking for the best firmware to run on the model G996b for the USA. I'm not getting 5G using Verizon or T mobile. I'm getting mixed messages doing research on if changing firmware can enable network bands or not and even I got the phone, it mentioned supporting n71 for 5g and that's the band my area mostly uses. So even if that specific band isn't built into this model, what would be the best firmware to run to use in the USA?
G996b does not officially support 71.
1, 3, 5, 7, 8, 20, 28, 38, 40, 41, 66, 77, 78 SA/NSA/Sub6 - SM-G996B

Question S22 Ultra: Is The Trade-off Of Getting Call Recording In The US Worth It?

I could really use some help and advice on a subject I've spent countless hours trying to research. I live in the US and just bought the S22 Ultra without fully understanding what I now know, that the Call Recording feature - which I must have - is entirely disabled on the native "U" and "U1" variants sold in the US.
Why Samsung does this when recording is predominantly legal in most states is beyond me. And why someone hasn't yet figured out how to hack the software to turn it on everywhere is a shame, but this is where we are now, and so I am trying to find a practical workaround.
I have been using Skvalex Call Recorder for years on other phones with mediocre results because of its inability to properly record the audio from the other side of the call with the microphone, so when I heard that this Samsung phone allowed native, actual call recording, I jumped at the chance to get my new S22 Ultra.
Boy was I wrong, because that's when I realized that the CR feature is enabled in only a handful of countries, not the US, and that the only solution short of rooting the phone is to change the CSC code Samsung uses to identify which country-based phones are permitted to use the CR feature.
Okay, I thought, that's a great solution, but boy was I wrong again!
Well, that sounded easy enough until I learned that you can only change the CSC code on a phone designated for the same region as the country, in this case either the "B" variant (for Ukraine) or the "E" variant (for India and all the remaining CR-permitted countries), but definitely not the "U" version I now own.
It quickly became clear that no US phone can ever have CR without rooting, and beyond the complicated process of rooting an S22 Ultra for most, not only does that step void your warranty and completely disable the Samsung Knox functionality which breaks many apps, it also disables all future OTA updates, and you lose most of the trade-in value after Samsung charges you hundreds of dollars for a new motherboard once the Knox fuse chip is tripped. So, rooting is really not a great option for the normal user who wants to trade in every year or two, and doesn't want to hassle with having to manually apply updates every month.
Okay, I said to myself, the only other alternative is to bite the bullet and buy one of the "B" or "E" variants from overseas and then change the CSC ode, which sounded like a perfect solution (setting aside the need to buy another phone) until I discovered that the US and International versions of the phone actually have slightly different specs, and this is where it all comes down to - and I really need some help with this! - whether the International version will even properly work in the US at all.
Well, I'm sure at least the "E" version with the same Snapdragon chipset as the US version will work, but the question is will it work well, will it work as well as the US version for everyday use, not for someone merely traveling to the US and is happy just making a connection??? What will I lose in either speed or connectivity on the AT&T network?
The issue seems to be that the two variants operate on slightly different bands, as you can see below. There is a fairly large amount of overlap between the two sets of bands, but from what I can tell the main difference that could/would affect performance is the lack of any 5G mmWave connectivity on the International variant.
Now, I have zero knowledge about most of this, and from what I can read in most cases mmWave is not all that useful, but again, the issue is whether getting call recording on my phone is worth the trade-off of not having the most complete set of available bands on my phone?
If I could ask you good folks to give me your best advice as to what is else is actually missing from the list below on the International specs that would affect everyday performance?
ANY HELP WITH THIS WOULD BE GREATLY APPRECIATED!!!

I'm no telco expert & not in the US, but I think you should be largely good with the E variant on 4G/LTE. If you need 5G, you may need to choose a provider who provides the widest assortment of bands. Moreover it seems the E variant supports far more bands than the US variant. You may check here:

If for some reason you are not satisfied, you may sell off the phone on Swappa etc. There are plenty of buyers interested in international variants as well.
I've traded in 2 rooted phones in the past and both recd full trade in value, $800 with no issues. However I do agree with your main point that it sucks that the US variants are absent call recording.
Just use Skvalex. It records fine on my unlocked NA s22u on AT&T. Even records wifi calls and VOLTE calls. Only one side on Bluetooth though.
