Hello urbanyetti,
Welcome to Apple Support Communities!
If we understand your post correctly, a third-party eSIM app that used to work in the past is now no longer working. We'd like to help!
Start here:
"Learn what to do if you can't set up an eSIM on your iPhone.
What is an eSIM?
An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical SIM.

What you need
* iPhone 14 models that are eSIM only can activate without a Wi-Fi network.
Follow these steps
Go to Settings > General > About and look for any numbers under EID. If there are no numbers, contact Apple Support.
After following each step below, open Control Center by swiping down from the upper-right corner of the screen. Check if your carrier appears in the status bar. If not, go to the next step.
- Turn Airplane Mode on and off.
- Go to Settings > Cellular and check if the number you're trying to activate is shown. If it is, turn off the line and then turn it back on again.
- Restart your device or devices.
If you still can't set up your eSIM, contact your carrier."

Lastly, since this is a third-party app, contact the developer if you still have issues, as they will know how their app works with iOS, and if an update is necessary:
