Is it possible to use US phones in korea?!

I have an aunt who is visiting me in America for a month. She will be going back in few weeks and she is interested in purchasing a note 3 in America since it's cheaper. Question is.. is it possible to use US based phones work in korea? Which carrier Note 3 would work the best?

In theory, the phone should "work", as long as you can get it unlocked from the carrier. They should all have quad-band GSM, so you should be able to get data too. LTE is a different matter though. South Korea providers use bands 1, 3, 5, and 8. Both the AT&T and T-Mobile Note 3s support band 5, but that's the only one, and the Sprint and Verizon ones don't support any of those bands. SK Telecom and LG U+ use band 5, but SK Telecom also uses band 3 and LG U+ uses band 1, so your aunt might not get full LTE coverage if they use those other bands to fill gaps or something - but I really can't guess.

How much does a Note 3 cost in South Korea (USD equivalent)? Because you can get a "international" Note 3 32GB (N9005) from eBay or Amazon for $550-560. It supports LTE on bands 1, 3, 5, 8, and 20. So while she's in the US, she could pick up a pre-paid SIM from T-Mobile or AT&T (not Sprint or Verizon) or one of their MVNOs and use it in her new phone. She won't get LTE, but she will get 3G. If you're in a city, I'd recommend going with a T-Mobile MVNO (MetroPCS, for example), since they have a very strong 3G/HSPA+ network. But more importantly, it'll work on all the bands in South Korea, regardless of carrier.

Samsung Galaxy Note 20 Ultra N986U1 or N9860 in UK.

Hello, I'd buy Samsung Galaxy Note 20 Ultra with Snapdragon chipset. But now is complicated. I don't know which one is better to buy N986U1 or N9860? I'll not root phone, even if I'll root than no problem with USA variant to unlock bootloader (xda-developers I read one thread samsung pwned). Other thing is 5G. Will it work in UK or not? I read tutorial how to enable all bands on LTE, 5G via service menu, so maybe will work. I'll be happy if FM radio works.

N9860 (TGY - Hong Kong) should work with 5G on the Three network in the UK, probably also with Vodafone. Definitely not with EE. Not much feedback about O2.
But the N9860 is getting appalling support from Samsung. No Android 11 yet and still stuck on November security updates. When updates are released they can undo service menu changes required to enable 4G+.
I can't comment on how the experience might be in the UK with the US versions, but so far I'm not impressed with Samsung and this phone. The hardware is great. The imported software support is a scandal. I would probably not risk importing again.

Thanks for repley. Maybe now doesn't makes a sense between Snapdragon and Exynos variant. Most S10 Plus, Note 10 Plus previously been imported from USA. But for Note 20 Ultra is absolutely different more from China. What is the reason for it. Because bootloader vy default can be unlocked or something specific. I'm using EE. So if 5G doesn't work I'll not worry so much.

I get up to 200 Mbps on EE with 4G+ and I'm really not sure whether the 5G coverage extends to my neighbourhood, so I'm not fussed that 5G does not work for me. I tried to find signal where it is claimed to exist and got nothing. 4G+ coverage is very good for me though, so happy days.
I don't know why it does not work. The required bands are supported and I've tested with 5G SIMs from EE, 3 and Voxi. I've contacted EE support and Samsung (UK) support and nobody gives a **** as the phone is imported.
My only real beef is the complete lack of updates. My S10+ is more up to date than this N9860. I have no idea why Samsung are dragging their feet over this specific model.

I will say this the N986U1 do get updates frequently and I'll the specs far as signals in your area

Thanks, I had Note 10 Plus with Snapdragon USA for short time and coverage was very better than with Exynos. With Snapdragon signal was perfect but with Exynos was weak and many times impossible to make calls.

Yea I had the Exynos Note 9 and the signal sucked in the US

Thanks for repley, so, I bought Note 20 Ultra USA variant.

N9860 has got Android 11 on Feb 3rd. And it is amazing.

Phone recieved and I'm happy with it. Flashed XAA U1 and no problem at all. Only for the moment is it issue on my side or phone, but ebay app doesn't work. It says:"
Try searching for something above or tap "Reload" to try again. Rest apps works without issues.
Update: I believe it was ebay issue. eBay app working now. All is perfect.

Is there a way to make the 5G of my US variant Note 20 Ultra to work in another country?

I have a Samsung Galaxy Note 20 Ultra 5G bought from the US (SM-N986U1) and I am currently in the Philippines. Is there any way I can make the 5G work here? If currently there is no way, would you think there will be in the near future?

Depends if the 5g bands are the same in both countries (and operators), you'd need to check that.
You could try the whitelisting method used on the Hong Kong variants which allows 5g use in Europe. Google it.

This is interesting part. I've been thinking about this not long time ago. My idea is as HK variant has same chipset etc, except storage with USA variant. So I believe it possible in some way to enable hidden or locked 5G bands on USA variant.

Not possible make to work because it do not support bands used bands and combinations used in Philippines: https://cacombos.com/device/SM-N986U

hi mate just for knowing, i had this idea to import myself a broken note 20 ultra 5g US variant, you said that the 5G is not working. Did the 4g,3g or 2g worked for you? im from italy and i found on ebay a good priced phone, but now im scared that the network will not work for me. i found the philippines band chart with all the frequencies and bands. like in italy, only one/two of them are supported and i would like to know if the network was working.

Hey there. Yes. My former Note 20 Ultra 5G US variant's 4G is working in the Philippines.
I recommend you get also the Hong Kong (Snapdragon) variant instead, as I have read somewhere that HK variant's 5G could work in the UK.

Well this answers my question. I recently bought a US version note 20 ultra 5g and having trouble activating the 5g on my phone which seems to be impossible. I should have bought a snapdragon hk version instead then. This is very frustrating cause I'm really enjoying the benefits of a Note phone.

Question Importing Unlocked S22 Ultra from USA to India, Europe, Asia

I have ordered the S22 Ultra from the US and hoping to use it in India. Can anyone confirm if the USA Unlocked S22 Ultra will work on Indian SIM Carriers? I have also read that Samsung Pay and Samsung Pass stopped working under such situations in last year's S21 Ultra. If anybody has any insight on this topic and solutions for it, please post them on this thread.

For curiosity may I ask reason to import from USA when this time India have Snapdragon already.

Basically through a friend of mine, i was able to order the Tab S8 Ultra 256gb with Keyboard and S22 Ultra 256gb (unlocked) for $1900, whereas the same would cost $3000 in India.

The samsung s22 ultrabought from usa works on airtel Sim in India. But I am not sure about jio Sim.
BUT THE CALL RECORDING FEATURE DOESNT WORK ON USA MODELS.
The usa models have an extra bandwidth chip installed on the right side corner of phone. That helps the device to work and have better network in low network areas like basement etc.
I personally checked this on iPhone 12 same models with same network jio one usa version and other Indian version. The usa version model was able to receive and make calls buy Indian model couldn't make and receive calls.

That’s the mmwave antenna not a extra bandwidth chip right?

Hi,
does 4G+ work? If that doesn't work it won't support NSA 5G too

Yes, you're right, that isn't a chip; it's an mmWave antenna that enables support for 5G frequencies well beyond the 6GHz range. Besides the US, few/no countries I know of have deployed or even planned on deploying these ultra-high frequency bands, so this antenna is practically useless outside the USA.

Is the phone a USA version?

If its indeed the USA version, You will have similar service on both ATT and TMobile but you will be missing band 14 on ATT which might effect your service. Also, you are unlikely to have much 5G coverage if that matters to you as this phone only has 3 of 5 ATT 5G bands and 2 of 4 TMobile 5G bands. The missing 5G bands are of the mmWave veriety so the only 5G you can get is 5G Nationwide which might actually be slower than 4G/LTE depending on the area.
