Cannot connect eSIM on new phone, how can I get it to work?

Hi,

i have read several topics here on how to activate the eSIM on new phone (I already have eSIM on my current phone). Unfortunately this is not working, and I think now something is stuck. I did following:

• requested eSIM on my new phone and used the code on my current phone
• chose an option of single SIM
• requested it and it started installing in my mobile service place
• it stated that it is on after a while, but there was no number or anything on
• I deleted this as there wasn’t anything else possible to do
• then I restarted my phone and received an email that I can activate eSIM; now in the app it says ‘download eSIM’
• I tried doing this but the error message popped up
• this is where I’m stuck

I hope it is clear enough and that you can help me. The phone is iPhone 15 Pro, if this is of any relevance.

Thanks!

Jovana
