Here too.
Thanks for that though, very important to know 
Are your sure VOLTE is fine on this model ? Have tested in my country with VOLTE activated on the watch ( calls on 4G network ) and when i place a call the watch down on 3G during the time of the call… Will remake a test when the 3G will disappear in my country.
In Gboard i can select and use hungarian language,but in phone default language no hungarian.
My updated firmware version is S13_C29_EN_V1.1_20251009_20251009_0852

My VWAR Core 5 cannot use 2G or 3G, just only 4G + no 3G network in my country, just 2G and 4G. I am sure the VOLTE vork. Are you sure you have a VOLTE enabled SIM?

I’ve cleaned up the thread. @christ
This thread is about the S13 watch / Vwar core 5. You’re welcome to create your own thread about returning watches to the seller…

Yes i’m sure my sim card is Volte, i’ve ask to the operator.
I made a 4-pin USB connector for my watch. The Freecad model is 3D printed and can be found here if anyone is interested. Pictures

I also received information from the service provider that they only sell VOLTE-authorized SIMs, but despite this, it started after authorization via SMS.This is Telekom.

Smartwatch developer helper app lets me select different combinations od 2g/3g/LTE than the watch itself or the telephony *# menu. Might be worth a shot.

Already checked. Smartwatch Developer Helper doesn’t work on S13.
I hope that the developer of Smartwatch Developer Helper will adapt the app for the S13 to allow, among other things, the unrestricted use of the Universal Launcher. There is still an unsilved permission problem here.

It does not unlock dev options, but it does give access to sub menus that are not available in the stock settings app.
Once dev options are unlocked with the dialler code, this is actually quite useful

I’m currently testing this for display over other apps permission…. Info is here User manual | Shizuku
Seems a bit hit and miss but it’s interesting
Once the two apps are installed and you have rebooted the watch, you need to run this via ADB
adb shell sh /sdcard/Android/data/moe.shizuku.privileged.api/start.sh

The seller sent me firmware and software from AliExpress. I reflashed my watch, and now it supports all languages. Version 1.5.
