I'm curious as to what doesn't work when you purchase an unlocked version vs Tmobile branded? Im told you may have issues with wifi calling/rcs/video calling/and visual voice mail....
2. How easy would it be once you get the unlocked version to flash the carrier software to make everything work and then flash back to original if needed to be for resale or warranty
The reason im asking is that samsung is giving a bigger refund on the unlocked version...

If you live in the US I think the unlocked version is just a SIM unlock. I think it is still the snapdragon version. Which means it will not be bootloader unlocked. I think you have to get the exynos version from an online retailer.

Note 9 was able to do this and I did it. I don't see a reason why you shouldn't be able o do it in Note 10+ once carrier firmware become available to be downloaded.

I pre-ordered the unlocked version myself and I have AT&T so it should be as easy as waiting for the carrier firmwares to become available on SamMobile and flashing with Odin. My interest is now with DeX supported with microsoft if Odin is even neccessary to flash firmwares anymore?

Very curious about this myself. I preordered the unlocked version because that gave me more value for my trade in. I'm curious if I get the unlocked version and flash TMobile carrier software. Will I then get tmobile updates ota?

It's been the same for years now, hardware wise phones are the same, you'll need princey odin to flash unlocked/carrier firmwares. I buy unlocked and flash the carrier unlocked firmware. No bloat but it has the carrier specific radio. I prefer the native caller Id, no bloat, and the RTT over the carrier bloat and video calling. Google duo is better anyway

Are you TMO or ATT? I have accounts with both.
I know WiFi Calling, which is what I really need as far as carrier goes, is usually more difficult with ATT.
If you are TMO can you get WFC to work without flashing carrier?

How long do you usually have to wait for the carrier firmware to come out?

Wifi calling has no issues on unlocked firmware with tmo. At&t I'm not sure but if you flash the att csc and and cp files, I do believe that's all it takes. I believe you need to flash the at&T AP file.

My Note 9 is unlocked. Using on T-MOBILE with no issues with WiFi calling. I am not able to use the stock visual voicemail though which I would prefer. With T-MOBILE I'm forced to use their visual voicemail which really sucks. Does anyone else know if they're is a way to use the stock visual voicemail on T-Mobile?

I saw posts that allow you to do that if you flash carrier firmware

I just use Google Voice and forward unanswered calls to there
