Hello there,

I have a removable eUICC (89049) from SYC. My phone on this test is POCO X3 NFC (surya), which is using Qualcomm SDM732G.

So, SYC said very clear that the eUICC itself doesn't have ARA-M. Which is no OMAPI support. But, since OpenEUICC are privileged and can using TelephonyManager, it's still can't read the eUICC.

Are there any ways to make the card are recognized by the TelephonyManager? Are there any solutions like Magisk Module, Xposed, etc?

*The card is still readable by card reader. But I want to make it readable by the OpenEUICC to make it hassle-free to not open & closing the sim tray.

Here's the log

There is nothing that can be done from OpenEUICC side if neither TM nor OMAPI ever returns a valid handle.

I see, so, I could say that the card isn't recognized by my phone (modem or something else)?
