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 had asked this on another forum, but did not get a straight forward answer. But I feel this is an important thing to know, so bringing this up again:
I just received the phone. It looks like this is the Tencent version. and the model number is 'i005DA'
If that is true, then according to the ASUS website, The following bands should be accessible:
5G (Bands N1, N2, N3, N5, N7, N8, N12, N20, N25, N28, N38, N40, N41, N66, N71, N77, N78, N79)
FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
TD-LTE (Bands 34, 38, 39, 40, 41, 42, 48)
WCDMA (Bands 1, 2, 3, 4, 5, 6, 8, 19)
EDGE/GPRS/GSM (850, 900, 1800, 1900 MHz)
But the seller says bands n71 (5G) and 12, 71 (4G) are NOT available in this model. I also verified that Tmobile has really poor reception because of lack of bands.
How do I know which VERSION (a, b, c, d, e, f, g, h) does the 'i005DA' model corresponds to ? Can Someone point me to some ASUS website or verifiable source that maps the model to the version number ?
I believe the answer you got was "G"
Re: Which version does ASUS ROG 5 model "i005DA" map to ?
Version G = ASUS_I005DA = China / Tencent Games

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
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.

There arent any call recorders in the play store that work correctly due to new Google policies. You will have side load it.

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...
