Check the number format
Enter the phone number with its country code and verify that it belongs to the person travelling. A desktop office extension may be useful for billing but may not help a driver reach an arriving passenger.
Plan a fallback
Consider whether the phone will have roaming or internet access after landing. Keep the booking reference and the service contact available offline. Follow the confirmed meeting instructions rather than relying entirely on a new message arriving.
Report contact changes
If another passenger will become the main contact, send the new details with the booking reference before the journey. Avoid changing several contact fields in separate messages without explaining which person should be called.
