Will unused data be retained after the plan expires?

No — unused data is not retained after the plan expires.

Once your plan's validity period ends, any remaining data will expire along with the plan and cannot be carried over to a new plan or used afterward.

To continue using data, you'll need to purchase a new plan. A couple of tips:

• If you're near the end of your validity period with data remaining, consider how much you actually need before topping up

• If you're topping up on the same eSIM (same ICCID), the new plan will activate automatically when your current plan expires — no reinstallation needed

You can check your plan's validity period and remaining data in the Tiger eSIM app or the Alipay mini-program.
