How does the Auto-refill feature work for the Lifetime lines of partners’ end users?

When the balance on a Lifetime Plan line drops below 100 MB or when the validity is under 1 day left, the Auto-refill feature automatically adds the same previously selected bundle to the line. The new bundle becomes active immediately, and its data is added to the existing balance on the line. Additionally, the validity period of the line is extended by 365 days, ensuring continued service for the end user.

The Auto-refill feature for partners' end users' Lifetime lines automatically adds new bundles to the line when the balance is low, maintaining a sufficient data balance and extending the validity period as necessary.
