Using European version in the US?

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?

So your carrier is ATT and your phone connects to Band 13? Might be software glitch which might be taken care of in the future firmware update or the info on websites isn't correct. There was a website that stated "Note 10 had UFS 2.0", but that was incorrect and phone indeed has UFS 3.0.

i looked at FCC and it states that it supports band 13???? but im not sure they tested band 13........ its so confusing 3 different websites say 3 different things but it DOES support band 13? because when i go to a rural area band 13 is the only band on verizon........ how is that possible if this phone doesn't support it btw i have a vzw sim in the att phone
MAJOR UPDATE SPRINT IS WORKING ON MY ATT PHONE! MAJOR MAJOR UPDATE FOR SOME REASON I POPPED MY SIMCARD FROM SPRINT ITS NOW WORKING WITH BAND 25 26 AND 41 WHY!!!! WHY IS IT WORKING! it doesn't make sense every provider including sprint it even brought up the SPRINT OMADM....IM SO CONFUSED RIGHT NOW BUT ITS WORKING WITH SPRINT! LTE AND ALL how is this possible? did they make the carrier pretty much UNLOCKED? remember this is an ATT variant

Does the NOTE 10 support all the 4g LTE bands? I GOT SPRINT WORKING ON AN ATT VARIENT! and tmobile and verizon works on it!

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?

Of course, the first image is the default APN settings and the second one is just an APN I added that I thought might've made a difference but didn't do anything

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.

This is Global/Europe version. Here have this model supported bands and combinations: https://cacombos.com/device/ASUS_I005DA (A-version).
If anyone have US version of this device and rooted, would be interesting to list this model to compare Global/Europe one.

To see combinations with 5G and 4G. 5G NSA require the device support anchor band (4G) and 5G together.

They don't appear to have data for other models of the phone.
https://store.asus.com/us/item/202105AM210000001 lists the information under "Connectivity" for the US version of the phone.
https://rog.asus.com/uk/phones/rog-phone-5-model/spec lists versions A - H under "Network Standard" for the Europe versions.
You don't need to be rooted if you know where to look.

Yes, that's what I found as well.
However as I am stating above I copied and pasted directly the bands from BH Photo's website stating the bands.
This is what I don't understand and I can't get clarification from them. That's why I asked as well if anyone had this model they could state which bands were actually in the device.
Something here isn't adding up right.

Hi
For a G996B/DS those are the frequencies available , some may be "activated" or not depending on the firmware ( branded firmware may exclude some of them) on the phone , a second page confirms the same frequencies
I would trust more this information to whatever BH has on their page
Also this page will tell which one of those bands will be good to use in the USA
I can check which band I am using at the moment but , i do not know how to see all available bands.. sorry

I looked at that page already with the frequencies. However if you notice they don't have the Latin America variant listed, which is what this is. This is about a very specific model offered by BH Photo that I am asking about.
Everything you are giving me I already found, which is why I asked here because of the contradiction and inability to get any answers from BH. I know what bands are used in the United States, so I'm good on that end. I did do searches prior to posting as noted, I was hoping someone who purchased it from them or has a Latin American variant could verify. Thanks

Hi
There is not a Latin American variant..... G996B is the international version (exynos 2100) , what they probably mean is that is has a latin America firmware or that the csc is from a latin american country , mine has a GTO ( Guatemala) CSC for the sales region code XXX/YYY,YYY/GTO that CSC has not influence at all the x and y does , I change mine to PHE , (Spain) PHE/PHE,PHE/GTO
It only changes the firmware but the frequencies are the same , you can flash an European firmware on it if you want it but the frequencies available will still be the same ones
There is not a S21 made for latin america

Just came across this thread and I own a G996B with the Panama CSC, but live in Canada. I don't seem to be able to connect to the 5G network in my city even though my phone has the required bands used by my network provider. Since its an Exynos phone and the NA variant uses Snapdragon, I can't flash an NA firmware because there are none. Is there a chance that my default phone firmware (Panama-based) has the bands disabled/not activated since Panama has no plan to roll out 5G?
I was going to try to flash an EU firmware , but none of the countries seem to be using the same band as Canada. So what I'm really wondering is whether the firmware matters or are all bands available regardless of firmware and it's just something else causing my phone not being able to use 5G?

Hi
I think firmware determine what frequencies are available but hardware also as the antenas are tuned specifically for certain regions
In you case , your phone has 3 out of 4 5G frequencies available , maybe , your luck , your provider uses the only frequency not available in your phone, check here . Find out what frequency they use , check your network mode , your access points configuration ...
CSC will not determine what frequencies are available at the phone , but you can change your active CSC to another ( pay service) like Europe

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

it uses

TDD LTE Band: B38
UMTS Bands: 1, 3, 8
LTE CA UL Bands: B7+B7, B38+B38
>>>bands 7 & 38 are main there
so now go to gsmarena

see specs
4G bands1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28, 32, 38, 39, 40, 41, 66 - SM-S908B
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)
