Hello,
I'm a European living in the US but also spending my time quite a bit in Europe. Therefore I want the dual sim version of the S10e.
Now I'm wondering how bad will it be using the European version in the US in terms of carrier support, reception, functions like WiFi-Calling etc?
As far as my research got me I found that the EU version is called SM-G970F and supports these LTE bands:
1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 17(700), 20(800), 28(700)
Compared to factory unlocked US version:
1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 38, 39, 40, 41, 46, 66, 71
The US carriers use these LTE bands (bold for main usage):
T-Mobile: 2, 4, 5, 12, 66, 71
Verizon 2, 4, 5, 13, 66
I guess that implies that for instance Verizon is not really usable at all and for T-Mobile I'd only have sort of half the network. Is this correct?
Is there anything else I need to consider before buying?
Thanks guys!

I'm using international version in the US for two weeks now, with Ultramobile (T-Mobile MVNO). I live in NY/NJ area and didn't experience any problems with reception, call quality on network speeds. WiFi Calling works great. On one hand I noticed that S10e shows less 'signal strength bars' than my previous phone (ZUK Z2), but on the other with Samsung I get some reception in placed where Z2 could not connect.
The only problem I've had are delayed notifications when screen is off (or even when app runs in the background). I didn't get notification when someone was calling me on WhatsApp, Signal or Messenger Lite. Only after couple minutes a missed call notification appeared. Turned off battery optimization and memory usage checking for those apps, but that didn't help. Searched the internet and many people have the same problem with Android in general (e.g. my wife experiences same issue with her Nokia 7). One thing that solves the issue is having a permanent VPN connection. I have NordVPN subscription and after turning it on all notifications appear immediately.

I have the SM-G970F with North American CSC but it is TPA (Panama).
I use tmobile and I get LTE+, wifi calling works, Volte (video calling works, HD calling works.
Only thing unfortunately that doesn't work is the "Caller ID and Spam Protection" in call settings. Anyone have a CSC they use that Caller ID and Spam Protection feature works?
I just got an SM-G996U1 US variant snapdragon 888, however, it does not natively support n78 band 5G that is used in my country, is there anything I can do to enable it?
I have tried the revice menu but it is to no avail.
csc is XAA.
Thank you for lending your time.

I tested the speeds with a local device that supports n78 band and it is at par. I am also baffled with what is happening.

Can you reveal your valuable solution here?
I also need n78 frequency unlock
Please tell us how you did it
Probably he has done it on Android 11 where the service menu was accessable
Now, there is no valid solution yet to activate or access to service menu on Android 12
Same issue I also need a solution. Android 12 unfortunately
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

so now go to gsmarena

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)
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.

what's wrong with installing a 3rd party recording app?
Callapp Contact record perfectly on USA or unlocked 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...
