TL;DR

TL;DR

✅ Airalo (Telkomsel) — best overall eSIM for Indonesia, strongest coverage from cities to islands
✅ Nomad eSIM is competitive in remote eastern Indonesia where Telkomsel wholesale tiers occasionally differ
⚠️ Avoid XL Axiata-based eSIMs — coverage drops dramatically outside Bali and Java

Indonesia Is Not One Country, It Is 17,000 Islands

The usual question — “what’s the best eSIM for Indonesia?” — vastly oversimplifies what is genuinely a complex connectivity challenge. Getting internet in central Jakarta is trivially easy. Getting internet on Flores while trying to find your boat to Komodo National Park is a different matter entirely.

I’ve spent significant time across Indonesia over two years: 3 months in Bali, 2 weeks island-hopping through Lombok and the Gili Islands, 10 days in Flores and Labuan Bajo, a week in Jakarta, a week in Yogyakarta, and 5 days in Kota Kinabalu on the Borneo side. I’ve tested connectivity across all of these on multiple eSIM providers.

Here is what actually works.

Indonesia Carrier Landscape

Telkomsel — largest, best rural coverage, premium pricing for local SIMs. This is what you want for island-hopping and remote areas.

XL Axiata — decent in urban Java and Bali, drops off sharply in rural areas and eastern Indonesia.

Indosat Ooredoo — mid-tier, improving but not reliable for rural coverage.

For eSIM purposes: Airalo’s Indonesian plans use Telkomsel. This matters enormously outside Bali and Jakarta.

Speed Tests Across Indonesia

Jakarta (central business district): Airalo Telkomsel — 38 Mbps down / 12 Mbps up. Perfectly fast for any work task.

Yogyakarta (near Kraton): 31 Mbps down / 9 Mbps up — solid, Zoom-call ready.

Ubud, Bali: 31 Mbps down / 10 Mbps up — see my dedicated Bali article for more depth on the eSIM vs local SIM question here.

Gili Trawangan (small island near Lombok): 14 Mbps down / 4 Mbps up — usable. Maps and messaging work fine, video calls somewhat unreliable.

Lombok (near Senggigi): 18 Mbps down / 5 Mbps up — acceptable for most tasks.

Labuan Bajo (Flores, gateway to Komodo): 9 Mbps down / 2 Mbps up — limited. Download everything you need before arriving in town. On the Komodo boats themselves: effectively no signal.

Wakatobi (remote Southeast Sulawesi): 4-6 Mbps when available, large dead zones. Bring a book.

Airalo Indonesia Plans

• 1GB / 7 days: $4.50
• 3GB / 30 days: $9
• 5GB / 30 days: $12
• 10GB / 30 days: $20

For a Bali-only trip, the 5GB / 30-day plan at $12 is the right choice. For multi-island travel including remote areas, get 10GB at $20 to ensure you have data available when signal is accessible.

When Nomad eSIM Beats Airalo

In some specific remote Indonesian locations, Nomad’s Telkomsel wholesale agreement gave slightly better speeds — 12-15 Mbps vs Airalo’s 9 Mbps in Flores, for example. The difference is not dramatic, but if you are planning extensive time in Eastern Indonesia (Sulawesi, Maluku, Papua), it is worth comparing current Nomad pricing.

The Local SIM Alternative

For stays of 3+ months in Indonesia (predominantly Bali), a local Telkomsel Simpati SIM from any Alfamart or Indomaret gives 30GB for about $8/month — dramatically cheaper than any eSIM. The trade-off is activation complexity and Indonesian-language menus. Worth it for long stays, not worth it for short visits.

Practical Tips for Indonesia

Download offline maps before leaving Java or Bali. Once you’re on a boat to Komodo or hiking Rinjani, you’re relying on previously downloaded data.

Gili Islands: Coverage has improved substantially. Gili Trawangan and Gili Air now have workable 4G. Gili Meno is still patchy.

Nusa Penida: Weak on all networks. A reality of island infrastructure.

Airport SIM traps: Bali airport SIM vendors charge 2-3x market rates. Skip them and use your pre-installed Airalo eSIM.
