## Review the relationship. Track its changes.

Choose a mobile plan with clear allowances and terms.

### Confirm the supported offer.

A prepaid package, eSIM profile and recurring subscription are different services. Confirm the market and lifecycle operations before designing a recurring checkout.

### Explain the complete terms.

Show data, calls, SMS, roaming, published recurring charges and the renewal period. Identify the subscriber, payer and person authorized to manage the line.

### Keep requests separate from active service.

A plan change takes effect on its recorded date. Cancellation and port-out need their supported processes and final billing checks; removing an eSIM from a device does not cancel a subscription.
