Why can't the top-up package be activated?

The original package has not expired; the top-up package will be automatically activated after the original package expires, no manual operation required.
The top-up package does not match the current card (e.g., purchasing a physical SIM card package for an eSIM); confirm the package type is consistent.
Payment is not fully successful; check the order status. If it is "pending payment", complete the payment.
Contact customer service to verify the top-up record and assist with activation triggering.
