Internet in the Gili Islands can support messaging, navigation and routine travel tasks, but performance varies by island, accommodation and network load.
Boat transfers and less developed areas make offline tickets and directions essential.
NoveSIM plans are data-only and do not provide an Indonesian number, conventional calls or SMS.
Quick answer: Use an Indonesia eSIM or registered local SIM and confirm the network used near your accommodation. Download boat details, the property location and essential documents before leaving Bali or Lombok.

Choose coverage for the correct island
Review Indonesia eSIM plans and Indonesian networks. Gili Trawangan, Air and Meno should not be assumed to perform identically.
Use accommodation Wi-Fi realistically
Wi-Fi quality depends on the property and backhaul. It may handle messaging but should not be the sole plan for scheduled remote work.
Prepare before the boat transfer
Save tickets, port instructions and contacts offline. Use Indonesia troubleshooting without deleting the profile if data fails.
