Practical checks before the travel day
- Carry enough battery power for the longest planned transfer.

- Save the first address, booking reference and one useful contact.
- Confirm that the exact handset is unlocked and supports eSIM.
- Keep installation details where another device can display them.

Safe checks if the connection changes
If data stops while using mobile Internet on Silhouette Island, confirm signal, the enabled eSIM and the selected mobile-data line. Data Roaming should be on for the Seychelles eSIM and off for the home line. Allow automatic network selection to register, try aeroplane mode and one normal restart, then verify data.esim only if manual APN entry is required. Do not delete the installed eSIM unless NoveSIM support specifically requests it.
