2. Dial *#272*719434266344#

it does not dial to *#272*719434266344# the error message was CONNECTION PROBLEM OR INVALID MMI CODE

Hi All,

I know everyone is frustrated that we are not able to change the CSC on Watch 4 Bluetooth version. I was keep on trying different methods and atlast i am able to change the CSC on my Watch 4 Bluetooth Model SM-R870. The funny thing is I tried all hard way and nothing succeeded. Finally find out a simple way to change the CSC.

1. Open the Samsung phone Dialer app on watch
2. Dial *#272*719434266344#
3. Accept the warning Menu
4. Change the CSC to MEA or SPAY supported Region (Its a one time change, be careful, you cant revert back to any other CSC)
5. Install and reboot
6. Select United Arab Emirates and reboot.
5. Done , Watch will be reset and Spay will be available once after pairing again with phone.

Please feel to thank me if its working.

Thanks,
TechDocAsia

I own the Bluetooth version of the Galaxy Watch 4...

Purchased via Amazon in the US, but was sent the International Model (SM-R870) instead of the US version Model (R870)...

I've tried the dialer method and code *#272*719434266344# and receive the following message...

USSD code running "Unable to process the request"

Please advice/help.

I don't know why everyone wants to be able to change the CSC (which comes with a lot of risks). I managed to get Samsung Pay on my watch by just changing the region after I resetted it. For me it was as simple as that. Currently I'm back on my own region as I don't need samsung pay, I have the apk installed to remap the samsung pay shortcut to google pay which is all I wanted from SPay, but try that first instead of the csc.
Can you please explain how you were able to change the country without changing csc? Is the watch 4 bluetooth variant you are mentioning about?

I tried this on my watch 4, indian version. I set CSC to XAA and samsung pay is available now. XAA is US and tied to no carrier. I was able to update the watch later on.

After XAA selection & reboot which County you selected?

Are you still getting the updates with XAA?

Also did it bring in BP and ecg features on watch with side load need of app on phone?

I have Watch 4 - Watch(BT)-SM-R870. Samsung pay is working for me. I change CSC to XSG - United Arab Emirates.
Also, I am getting updates(image attached)

Also, Now I can use ECG & BP too via moded Apks.

Thanks for this post🍻

Are you still getting the update and after XSG which country you selected?

Can you elaborate how to chage region without changing csc

Avirendra, did you find such way without changing csc?

Also I see you have great deal of posts, inputs and updates here. Appreciate it

I would like to your opinion that which csc would be better to make a choice MEA, XSG or XAA. The latter two are saying they are getting updates. Where as the one your watch 4 is MEA and you aren't getting OTA & have to rely on service center offline updates.

I'm looking forward to change csc on my watch 4 and hence such curious question since this is just one way street to change CSC.

Confirmed working like a charm and also got an update after changing csc. So update is also working..Also managed to add indian cards… Thanks a lot for sharing this
@ankushgautam

Did you use CSC as MEA and UEA as country as there are users who aren't receiving updates on using MEA - UEA combo.

Please confirm CSC, Country you chose and if you received latest over the air update or not. Thanks.

    Moved to Watch 4 Classic 46mm from Gear S3 after 5 Years, immediately after first setup found out that SPay is still not officially supported in India on WearOS as well. Changed the CSE to MEA and the region to XSG and doing the setup after wipe reboot, lets see how it goes.


    Edit 1: First time setup got stuck after Samsung account setup, watch kept showing "Check your phone for setup," but on the phone it was again searching for the watch. Reboot watch and then trying the setup again.

    Edit 2: Setup was successful, SPay app is there. restoring data first.

    Edit 3: Sideloaded the Spay Watch plugin and boom I am in all my old cards from Gear S3 are present, restoring them.

    Finally back to Spay on Watch 4

    Attaching some shots from setup.

    Let's wait for next watch update.
    Will wait for your response on updates, I switched the same for Gear S3 to watch 4 classic, Broken Updates are my fear to not moving on which CSC change.

    Yes right, you won't know until new update happens.

    And like you I have also updated the watch but just want to be sure before I proceed with CSC change.
    Also, I don't think there is an option to select XSG using the dialer code trick. There's only MEA.

    After you select MEA and reset then reboot.. you can select your desired country..which is UAE, this is XSG.

    You can change this region after a reset to any country in the middle east. So each region will give you a different CSC in the middle eastern aka MEA region.

    What has that to do with this thread? Google not working?
    I think he is referring to method above mentioned to change CSC of watch. I experienced this too. When we dial the given code on watch it get transfers to phone as a regular call.
