• ⚠️ eSIM hotspot sharing may be unstable; personal use is recommended.
• ⚠️ After installing eSIM, please do not manually select "Remove eSIM" . Removing it will be considered as discarding and terminating its use, and it will not be able to be reactivated later.

• ⚠️ Based on fair usage principles, telecom operators may limit speeds or suspend network services for users with large data usage over a short period. It is recommended that you disable automatic updates and automatic backups to cloud storage, and avoid prolonged video watching or mobile gaming. If you have heavy data usage needs, it is recommended to connect to local Wi-Fi.
