Can't connect to 5G network

Hello everyone
Just got my hands on the Galaxy A90 5G from south korea SM-A908N KTC. I live in kuwait city got the 5G internet package from Viva telecom but can't seem to connect to the 5G network shows only LTE+ where ever i go even close to a 5G node. Checked our supported frequency band the phone supports it. Noticed in the settings there is a KT twophone service and when starting the phone 5G KT logo appears. My guess it's locked to KT telecom network.
So far only 3 firmwares available for this phone china, korea UK. Can i change the firmware to another region like UK BTU change the CSC file and check if it work?
Thank you and sorry if this thread is not suppose to be posted here i have low posts

Question 5G bands in the SM-G996W

Hello,
I am looking to buy an unlocked S21+ from Samsung Canada store (SM-G996W) and I checked here :
S21+ Differences that the following 5G bands: n2, n41, n66, n71 are the ones supported by the Candian model so my question is:
Is it possible to change the supported bands? For example, if I travel to a country where the used 5G band is the n28, will the S21+ support this band. If so, how please?
Btw, I have seen some users changing Network bands on Samsung devices without root so I want to make sure that it works with the 5G bands especially from someone who have a S21+ please?
Here is the link of the short tutorial: Un/Locking LTE Bands on Samsung I am talking about.
Thanks for your help

AFAIK this 5G bands are hardware related, not software related. So no "unlocking" in this case.

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.

SM-A426B in Europe versus SM-A4260 in Asia (Hong-Kong): 5G reception problem

I bought a Samsung A42 5G from Rakuten. It is a 8Gb RAM version, model SM-A4260.
I live in France, and I use Prixtel MVO with the Orange network (3500Mhz antenna for 5G already open where I live).
5G is not working, even if the model I use has the good 5G bands:
Network: 5G: n1/n3/n5/n7/n8/n28/n40/n41/n78/n79 / (France is using n3, n28 and n78 right now).
Is it possible that it does not work because it is not the SM-A426B european model ? Software volontary limitation ?
4G LTE bands work perfectly...
Any idea to solve my problem ?

Do you think it is possible to flash the official international ROM of the SM-A426B on this Asian SM-A4260 version ?
The hardware seems the same...

Question 5G support on Exynos variant outside Europe.

Hi Everyone,
I purchased a S22 Ultra while I was living in EU. It is the Exynos Variant. I moved back to India and I can no longer connect to any 5G providers. My SIM supports 5G and 5G works when the same SIM is inserted on any other phone. The model is SM-S908B/DS and is on the latest One UI 5.1. I have tried contacting Samsung support but none of them seem to have any answer for this.
Does anyone has the same problem or the Exynos Variant doesn't support 5G outside of Europe?
Apologies in advance if there's already a discussion thread for the same.
Regards
Yash

S908B Exynos is not sold in India so it probably doesn't contain 5G configs for Indian carriers. Good luck contacting Samsung India or Indian carriers, they highly won't provide support for S908B.
There's a thread about enabling all 4G/5G bands, but it's for Snapdragon only.
Best way is to trade in your device for an S23U S918B (sold everywhere except USA, Canada, China, HK, Taiwan and South Korea)

Did you try to reset all network settings only in settings? Or may be try to change region CSC.

I don't have S908B, but might worth a try.
Use Samfw tool to change to every possible CSC, see if it works.
Sorry bro, my fault.
