## Match the service. Follow the purchase.

Add an eligible package to an existing eSIM.

### Use the profile’s eligible offers.

A package covering the same country is not necessarily a valid top-up. Compatibility belongs to the allocated service and its supported offers.

### Explain when the data becomes usable.

Present coverage, allowance, validity, published amount and currency. Explain whether the package starts immediately or follows the service’s stacking rule.

### Recover an uncertain order.

Retain the original purchase reference and follow funding and fulfillment. A delayed balance observation is not evidence that the top-up failed or permission to buy it again.
