To find the option for eSIMs on your Note20:
1. **Open Settings**: Go to the Settings app on your Note20.
2. **Connections**: Tap on "Connections" or "Network & Internet", depending on your device's setup.
3. **Mobile Networks**: Look for "Mobile Networks" or a similar option.
4. **SIM Card Manager**: In this section, you should see an option for managing SIM cards. The eSIM option should be visible here if your device supports it.
If you don't see an option for eSIMs in these settings, it's possible that your carrier or region doesn't currently support eSIM functionality on the Note20. In that case, you may want to check with your carrier for more information.
