Best eSIM for Indonesia in 2026: 6 Providers Compared (Real Prices)

Bali, Jakarta, Yogyakarta, the Gili Islands — Indonesia covers a lot of ground, and so does the pricing on eSIM data here. I checked live pricing across 125 providers we track for Indonesia, and the picture has shifted since I first wrote this: a provider most people haven't heard of, 4S eSIM, now dominates unlimited pricing at almost every length.

The quick answer

• Cheapest unlimited for a short trip (3 days): eSIMCard at $9.42, narrowly ahead of Maya Mobile's $9.99.
• Cheapest unlimited week, by far: 4S eSIM at $5.87 — a genuine outlier, roughly a third of what everyone else charges at that length.
• Cheapest unlimited month: 4S eSIM again, at $42.38 — well ahead of Maya Mobile's $49.99.
• Best value if you don't need unlimited: Ubigi, at $2.50 for 1GB over 7 days — the cheapest entry point in this comparison.
• Best for heavy data users: Nomad eSIM's 50GB for 45 days at $41.00 — more data, more validity days, and cheaper than Airalo's 50GB/30-day plan at $49.00.

What you'll actually pay: six providers compared

eSIMCard

The best short-trip unlimited pick: $9.42 for 3 days edges out Maya Mobile at the same length. Its 7-day and 30-day tiers are solid but no longer the cheapest once you factor in 4S eSIM.

4S eSIM

The real story here — $5.87 for a full week of unlimited data is dramatically cheaper than anything else on this list, and its $42.38 30-day rate beats even Maya Mobile's flat global rate. Worth checking first for any trip of a week or longer.

Airalo

Airalo's Indonesia lineup runs from small fixed-data tiers (1GB for 3 days at $4.50) up to 50GB for 30 days at $49.00, plus a full unlimited ladder from 3 days ($11.00) to 30 days ($69.00). It's a genuinely broad range, but its unlimited pricing no longer leads at any duration we checked.

Nomad eSIM

Nomad eSIM is the fixed-data value pick here: 1GB/7 days for $4.00, 10GB/30 days for $19.00, and a standout 50GB over 45 days for $41.00 — more data and more validity than Airalo's equivalent 30-day plan, for less money. Its unlimited lineup is thin, though — only 5-day ($18.00) and 10-day ($33.00) options, nothing shorter or longer.

Saily

Saily covers the most unlimited durations of anyone here — 5 through 30 days in several steps, from $18.99 up to $59.99. Its fixed-data tiers ($8.99 for 3GB/30 days up to $35.99 for 20GB/30 days) sit in the middle of the pack: not the cheapest, not the most expensive, but reliably available at every length of trip.

Ubigi

Ubigi now has the cheapest entry point in this comparison ($2.50 for 1GB/7 days) and has the best fixed big-data deal too: 25GB for 30 days at $28.00, cheaper than Airalo's or Saily's 20GB/30-day tiers despite offering more data. Its unlimited pricing ($24.00 for 7 days, $59.00 for 30 days) no longer leads the unlimited comparison the way it once did, now that eSIMCard and 4S eSIM are in the picture.

Maya Mobile

Maya's flat rate — $9.99 for 3 days, $19.99 for 7 days, $27.99 for 14 days, $49.99 for 30 days — is still a solid, simple pick, and the same flat rate applies wherever Maya covers if Indonesia is one stop on a longer Southeast Asia trip, but it's no longer the outright cheapest unlimited option at any single duration.

Why the prices are all over the place

Airalo, Nomad eSIM, Saily, and Ubigi all mix fixed-data and unlimited tiers, and none of them offer the exact same set of durations, which is why Nomad eSIM has a gap at 7 and 15 days where Saily and Airalo don't. On the unlimited side, Maya Mobile's flat global rate used to be the default recommendation, but eSIMCard and 4S eSIM both now price Indonesia specifically, and 4S eSIM in particular undercuts everyone by a wide margin at both the 7-day and 30-day marks.

If you're unsure how much data you'll actually burn through, our data usage guide is worth a look before defaulting to unlimited — most travelers use less than they think, and Ubigi's or Nomad eSIM's fixed tiers make that meaningfully cheaper.

How to pick based on your trip

A few days in one place: Ubigi's 1GB/7-day plan at $2.50 covers maps, messaging, and social media without paying for data you won't touch.

A week to ten days: 4S eSIM at $5.87 is the cheapest unlimited option at this length by a wide margin.

A full month, fixed data is enough: Ubigi's 25GB/30-day plan at $28.00 is the strongest fixed-data value here — most travelers won't get close to using it all.

A full month, you want unlimited: 4S eSIM at $42.38, well ahead of Maya Mobile and Ubigi at the same length.

Island-hopping with heavy data use (photos, video calls, navigation): Nomad eSIM's 50GB/45-day plan at $41.00 gives you both more data and more time than a standard 30-day allowance.

A few things worth knowing before you buy

Coverage is strong across Bali, Jakarta, and the other major tourist hubs. More remote islands and rural areas can be patchier — worth checking a provider's coverage page directly if you're headed somewhere off the well-trodden route.

Install the eSIM before you fly. Every provider here lets you activate once you land, so there's no need to hunt for airport wifi to scan a QR code on arrival.

Double-check your phone is eSIM-compatible and carrier-unlocked before buying — our compatibility guide walks through exactly how to check in under a minute.
