Each eSIM is linked to a single order.

📶 What Happens After High-Speed Data Runs Out?
Once your high-speed data is used up, the connection will automatically switch to low speed (up to 200kbps). You can still receive messages, use LINE, and browse the web, but video streaming or large downloads may not be smooth. The low-speed connection will remain active until your plan expires.
For unlimited data plans, high-speed access will resume after midnight (00:00) the following day.
