Hi ​@Oskiko9 

I do apologise that you unable to use you eSIM please check:

1. First, restart your phone and manually check that your iD Mobile eSIM is active under SIM manager in settings.
2. If you are still unable to use the eSIM follow the below:

• For Samsung Network Settings:

Open Settings by swiping down from the top of the screen and tapping the gear icon, or find the Settings app in your app drawer.

Tap Connections (or Network & Internet, depending on your model).

Select Mobile Networks to access options such as:

Network mode (e.g., LTE/3G/2G auto connect)

Data roaming (enable if you want to use mobile data abroad)

Access Point Names (APN) (check or update if mobile data isn’t working)

Network operators (choose manual or automatic network selection)

For Wi-Fi calling, go to Connections > Wi-Fi Calling to enable or disable it.

If issues persist, try resetting your network settings via:
Settings > General Management > Reset > Reset network settings
(Note: This will reset Wi-Fi, mobile data, and Bluetooth settings.)

• iPhone Network Settings:

Open the Settings app on your Home screen.
