eSIM Activation on SM-G988N (Korean) by changing CSC. If Possible ? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I'm struck. Could you please give me some help. I have imported SM-G988N Korean version in India because of Snapdragon. Initially I thought its a single physical SIM phone and eSIM can be activated by putting a request to my carrier since they have eSIM support. My carrier converted my one physical sim to eSIM but it never got activated on the phone. I rooted and If flash G9880 (HongKong) CSC will it get support of eSIM. ?? I desperately need second number activation or else I have to change my ULTRA as daily driver.
Its so important for me to stick to Ultra that I had to create a new thread for getting clarification/Help

G9880 (HongKong) No eSim Brother.

None and you wouldn't be able to change to any other csc other than KOO, KTC, LUC and SKC which are all Korean csc.

S20+ CSC Change

Hello Everyone,
I have the SM-G985F/DS in Canada. The current CSC is XSP/XSP,XSP/XSP.
This phone is the international variant. Can someone please guide me on how I can change the CSC? I am a total noob. I would like Samsung Pay/ VoLTE to work. Preferably Fido CSC or Unlocked Canada, some bands aren't working properly.
If this isn't possible will I get updates for my phone?
This has been a big headache.
The phone is Exynos and I'm in a Snapdragon country.
Thanks

Since you're using an Exynos phone in a country where they officially sell the Snapdragon variant, you won't be able to flash the Canadian CSCs since they're only available for the Canadian variant.
VoLTE should work after you insert your SIM and reboot the phone, I've seen multiple reports of VoLTE no longer requiring the correct CSC to function.
Messing with band support is almost impossible on Exynos variants and I believe Samsung Pay requires the correct CSC to work so you're out of luck there.
All this aside, you will still get OTA updates based on when they're released for the XSP CSC.

Changing csc

Recently i bought a snapdragon s20+(g9860) hong kong model.
I want to change my csc to european csc to get faster updates.
Is this possible?

You qoute is misleading.
The guy you qouted has a UK device and changed his CSC from branded Uk to unbranded UK, which both are on his device..
This guy here has a HK device and wants to to a European CSC. HK devices dont have European CSC on them, so he cant change to them.
Even if he roots the device, copies the CSC he wants from an EU decive to his and managed to change his CSC with wiping, not only he wont get quicker updates, he wont het updates at all because his CSC wont be an official CSC of a HK device

My apologies I guess I misunderstood region csc changes. Thank you for the clarification. I am new to Samsung devices so it's a learning curve! Appreciate the detailed reply
Ok guys no problem....i guess this is the downside of buying a snapdragon....but the only one.
Love this phone!

Try this - Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press dial, you should see a screen with the list of available CSC codes for your device. Select the CSC that you want and tap the Install option. This method works on the S10, it should work on the S20 as well.

Makes sense, Samsung can sell the same device to all carriers. If it's modeled like OXM on Exynos variants once you insert a compatible SIM the CSC is automatically updated after startup. That's really good news, users can switch carriers without flashing new firmware. Curious if Branded US Models have the same option, I would think they do. Thanks for the info, appreciate it!

eSim on Galaxy S20 5G, SM - G 9810.

I recently got the Galaxy S20 5G, SM - G 9810.
The menu item "eSim" is missing in the SIM card management for the mobile phone.
Thought all S20 can also eSim?
Does anyone have any idea how to get the menu displayed?
Maybe with a different firmware? There is firmware from China on it.
Wanted to run an eSim, SD card and another real Sim in the cell phone.

You have the S20 Hong Kong Variant. eSim isn't available on your device and changing firmware from TGY, which is the CSC on your device, to a different CSC usually creates more problems than it solves. The Forum is littered with users who have numerous issues after changing firmware. Firmware is CSC specific so altering this compatibility can have adverse effects. Carrier Aggeration, Wifi Calling, Samsung Pay, Samsung Health, Secure Folder as well as your Warranty may be at risk.
Another option if you want to have Dual SIM and SD Card is adding an adapter. I wouldn't consider that since it's a pretty funky setup.
https://www.simore.com/en/dual-sim-adapter-galaxy-s20-ultra-samsung-speed-zx-twin.html
On my Galaxy S8 I shaved a SIM Card, fixed it to the back of my SD Card to facilitate the setup you're hoping to achieve however Samsung squashed that option on S9's and likely S10's and S20's. I'm curious why you feel eSim is vital? It's much easier just to swap out the SD Card with a SIM when Dual SIM is beneficial.

According to Samsung Support, which I would take with a grain of salt, a future update may enable eSim on Snapdragon Devices. The Snapdragon 855 SOC is compatible with eSim as evidenced on the Galaxy Fold and I would think the 865 SOC on the S20's is as well, however at this time I'm not aware of any eSim enabled S20's with Snapdragon SOC's.

There is no bloatware whatsoever on this model. This model does support WiFi calling and VoLTE but its whether your Service Provider supports it. There is no in call recording app native.
I have the S20+ Hong Kong version with the TGY csc, but I cannot get volte and vowifi to work. I am on Orange Romania and I know for a fact that my carrier does support these 2 features. I even have the option to turn them on in settings, but they do not do anything. As for 5g, this phone doesn't have the bands used in my country, nor the mmwave hardware so guess I'll never have it. But is there anything I can do to get volte and vowifi working?

If you are getting volte option in settings then you just need sim of operator which supports volte feature. Like I'm in India. If i do not have volte feature in my phone then I cannot make calls to anyone with my Jio sim(operator- Jio). But there are other operators like Vodafone, Airtel. These also support volte but also work without volte

Enable eSIM feature on Samsung S20+ SM-G986W

Hello Experts,
I have a Samsung Galaxy S20+ 5G purchased in Canada and not associated with any service provider. I am planning to use it in India and I have 2 SIM's in India. Samsung Canada Firmware does not have eSIM feature and there is no SIM Card Manager function in settings. Can I flash any other region firmware and have the eSIM feature enabled ?
The question should b e, does the snapdragon variant support e-sim, cos am stuck with a S20 +5g purchased in usa but no e-sim
Galaxy devices in India are typically Exynos variants which offer eSIM functionality. Flashing different firmware on a Galaxy S Series Snapdragon variant won't enable eSIM. None of Galaxy's Snapdragon variants except The Fold are eSIM capable.

all s20+ 5g should support esim. (esim is inegrated to a snapdragon chip) BUT some of them are dissabled by software. but such a models like 986U or 986V, for example, were lock by operator and you could not install a software from U1, that includes esim support. i might be wrong. i installed U1 soft to a 986W model (that was without esim support. Now, esim works perfect. s20+ updates online. samsung pay works correct, knox works as well)
