Dear O2 team
After a lot of frustrating phone calls and visits to O2 shop without any resolution, I am now trying my luck to find a solution here.
I use MultiSIM and eSIM service from O2. I used it in multiple devices. I noticed a couple of months ago that all the eSIM cards that I had installed on my devices were working fine, but on the O2 App and Website, I always see that the eSIM cards are not installed and are ready for installation. I kept ignoring this error, but now when I tried to switch my eSIM to a new phone, I realised that it was a big issue as my entire SIM Verwaltung option had stopped working.
I can no longer see the details of my SIM cards, activate them, order eSIM profile, change the name of the SIM card. All these services are blocked and I simply get an error.
The error screenshot can be seen below.


On the O2 App, the error message is different depending on where I open the app. On Android App, I see the following status which shows that none of the eSIM cards that I have in use are installed, but all of them are active. This is weird because I am still using these eSIM cards so I do not know how they are shown as ‘Not Installed’ on the O2 page.

Could someone help me here tpo resolve this problem.
Best regards
Ankit
