After successful payment, I found that the package information was selected incorrectly (e.g., country, data, validity period). Can I modify or get a refund?

It depends on the package activation status:

1.Unactivated Packages: Full refund available within 3 days.

2.Activated Packages: Refunds not supported.

3.Activation Failure: Refund will be processed within 48 hours after verification.
