S24 - wifi calling through second SIM's data

[SKB24]

Hello all,

So I have dual eSIM setup on my S24:

 - local provider esim

 - Overaeas provider esim

I can make calls over wifi with both SIMs no problems. Issues appears when I am away from wifi. I can't make a phone call from overseas SIM using local SIM's data. I used to be able to do that on my s21 ultra, but have not been able to make it work on s24 from day one.

Maybe it a limitation in android 14? Anyone has any experience with this?

Cheers

Do you have any update on this? I am also anxious to know about it.  I know this feature works in my iPhone, but I just got a new s24 ultra.

Hello Online919, no update really. I tried a bunch of SIMs, of different providers but no success till now.

I have gone ahead and manually selected a forbidden network so that the sim network connection would fail, but the phone still does connect via other SIMs data.

So, an update on this. I'll provide some details. I am working with three SIM providers mainly:

- Telstra (Australia)
- Tello (USA, T-mobile)
- Jio (India)

Currently in Australia, was able to get backup calling to work on Jio using telstra data. So a win there.

No luck with Tello mobile, it show status "emergency calls only", but when connected to WiFi, calling works as normal. So this feature is carrier dependant, as we already know. Tello supports WiFi calling from sim data, as stated on their website. Wondering if carriers are adding support for the new phone on the backend... not sure 😕

Will be in China next month will update from there too. Will be using international plan from Telstra and Amaysim... stay tuned 👀

Tello says they support this, a representative in reddit told me it should work. I wasn't able to make it work in my s22+.

Please keep us posted on your updates.
