ESIM and how it work

[higuita]

Hi

I'm new to ESIM, so sorry for any stupid questions!

i have a volla X23 and 2 SIM, one personal, one for work. I will travel in a few weeks and wanted to buy a data ESIM, but several ESIM apps report no ESIM. So i'm a bit confused, i don't find anything to enable ESIM in the Volla OS.

Must i disable one or both SIM to use ESIM? or even really remove one or both SIM cards? is any special app or setting that i'm missing

Best regards
higuita

I never used eSim myself.
The only thing I know is that the entry OpenEUICC in Settings->Network is for eSim.

On my X23 it won't open , there is a short message telling me "no EUICC device found" and it closes again.
I also have 2 physical Sims installed. I assume that maybe one has to remove one Sim, but I am not sure about that.

As I do not own an eSim myself I did no further investigation on that.
