Check the actual phone and selected offer before purchase. Device support and destination coverage are separate requirements.

## Check the device. Review the offer.

Check the device and destination before purchase.

### Verify the market variant.

Similarly named devices can have different SIM arrangements. Check manufacturer guidance, carrier lock and the number of simultaneously active lines, not just stored profiles.

### Confirm each included service.

Review data, voice and SMS independently, along with hotspot and reduced-speed rules. A phone number associated with an eSIM does not prove that ordinary mobile calling is included.

### Test the selected line.

At a covered destination, select the intended data line and apply the package’s required network settings. Keep the device result separate from provider and order status.
