How long does it take for ICBC to automatically cancel SMS notification?

ICBC Messenger Service will be charged at one time according to the opening period when it is opened, and will be cancelled automatically after it expires.

If automatic extension is selected when opening, the service fee during the extension period will be deducted at one time when the automatic extension expires. If the balance on the card is not enough for the extension fee, the extension is unsuccessful and the courier service will automatically stop.
