Indonesia & Bali eSIM picks

At a glance

• Best for Bali digital nomads: Dracotel — balance carries across return trips and you can pick the carrier
• Best for a 1-week Bali holiday: Nomad Indonesia 5 GB plans
• Best for island-hopping (Komodo, Gili, Java): Airalo Asialink
• Best for streaming-heavy stays: Holafly Indonesia

Network notes

Telkomsel has the deepest coverage including most outer islands. Indosat and XL are competitive in Bali and Java. On Komodo, Flores and remote Sumba, expect 3G or nothing — bring offline maps.

Practical connectivity tips

• Install before landing. Denpasar airport Wi-Fi exists but is slow during peak arrival times.
• Apps you’ll want online: GoJek and Grab (essential for rides and food), Google Maps, Maps.me for offline trails, Klook for activities, WhatsApp.
• Scooter rentals are usually booked via Grab/GoJek or local WhatsApp — having data from the moment you land matters.
• Ferries to Gili Islands and Nusa Penida often have no signal for the duration. Download what you need.
• Bali coworking spaces have Wi-Fi but coffee shops vary; an eSIM with hotspot is a real productivity multiplier.

Watch out for

• Surf spots and hill villages (Sidemen, parts of Munduk) can have weak signal. Don’t rely on Maps for navigation in remote areas.
• Komodo National Park boats: often no signal for hours. Download guides and music.
• Indonesian SIM registration laws apply to physical SIMs, not eSIMs — one reason eSIMs are particularly convenient here.
