About this warning message
Many smartphones include built-in features that:
Notify you when data usage exceeds a certain amount
Help you monitor your data usage
Because of this, a warning message may appear when your smartphone exceeds a preset data usage threshold, regardless of the actual data allowance of your eSIM plan.
This does not affect your eSIM
Even if this warning appears, it does not mean that your eSIM plan has ended or that your mobile data connection will stop.
Please refer to the separate instructions for checking the remaining data allowance and usage status of your current eSIM.

Depending on your smartphone, you may be able to change or disable the data usage warning from the device settings.
Please check your device settings or help information if needed.
