This SIM card supports online recharge to extend your service duration.

For daily data plans (3GB/day), a recharged plan will automatically activate the day after your current service period fully expires.
- Important Note on Same-Day High-Speed Data:
Recharging does NOT immediately restore high-speed data on the current day if you have already consumed your 3GB quota. Your high-speed allowance will naturally reset at 0:00. If you require immediate high-speed data on the same day, please consider purchasing a separate new SIM card.
