Greetings!
We appreciate your post in the Apple Support Community. If you're experiencing unexpected data usage on your eSIM even with data roaming turned off, follow these steps:
Check app data usage and disable background app refresh for unnecessary apps.
Reset cellular data usage statistics in settings.
Contact your service provider to investigate unexpected charges.
Disable data for the eSIM in settings.
Ensure your carrier settings are up to date.
Use Airplane Mode with Wi-Fi when needed.
Review app settings for background sync.
Working with your service provider is crucial to identify and resolve any data usage and billing issues.
