Best eSIM for Indonesia in 2026
eSimania is the value pick for Indonesia. It is about $2.40 for 1 GB over 7 days and $9.00 for 5 GB over 30 days, cheaper than Airalo on every size here, so there is no rival price win to flag and we route to eSimania. Indonesia now has three network groups rather than five, after the government approved the Indosat and Tri merger in 2022 and the XL and Smartfren merger in April 2025. For a week or two, 5 to 10 GB suits most trips. Prices verified August 14, 2026; speeds are carrier-dependent and never guaranteed.
Whether you are surfing in Bali, diving around Komodo or working remotely from Canggu, Indonesia is well covered in the tourist hubs, with Telkomsel, Indosat and XL running the networks. A travel eSIM installs from a QR code before you fly, so you land at Denpasar or Jakarta already online. Coverage does vary a lot once you leave Bali and the big cities, which we cover below along with an honest dated price check and how to size your data.
Only going to Bali? This page covers Indonesia as a whole, including Java, Lombok, Komodo and Sumatra. If Bali is your only stop, our best eSIM for Bali guide is the one you want: it prices the same plans but adds coverage by area for Canggu, Ubud and the Nusa islands, and the SIM registration rule travelers ask about.
Our Indonesia picks
Best value for Indonesia: eSimania Indonesia eSIM
Data-only Indonesia eSIM, 1 GB to 50 GB, 7 to 30 days
1 GB $2.40 / 5 GB $9.00
eSimania is the clear value pick for Indonesia: about $2.40 for 1 GB over 7 days and about $9.00 for 5 GB over 30 days, cheaper than Airalo on every size here (Airalo local Indotel plan is about $4.50 for 1 GB, $13.50 for 5 GB and $21.00 for 10 GB). It is data-only with instant QR delivery. One thing to check for Indonesia: coverage outside Bali and the big cities is thinner on every network, so confirm the plan if you are heading to remote islands. Prices checked on eSimania and eSIMDB on August 14, 2026; speeds are carrier-dependent.
Pros
- Cheapest 1 GB we found, about $2.40 for 7 days
- 5 GB at about $9.00 and 10 GB at about $13.50, both under Airalo
- Data-only with instant QR delivery
Cons
- Marketplace does not name the Indonesian carrier
- Coverage outside Bali and cities varies a lot by network
- Data-only, so no phone number or SMS
Best for: Island-hopping and multi-region Indonesia trips: maps, ride-hailing, messaging and photos.
Multi-country alternative: Jetpac eSIM
Data-only eSIM, single install covers multiple countries
For a route that crosses borders, Jetpac has plans in 200-plus destinations on a single eSIM, with one install covering multiple countries, and free airport lounge access if your flight is delayed 60 minutes or more. Travelers report it tends to run on the 3 (Tri) network in Indonesia, which is fine around Bali and the main cities but weaker in remote areas, so it suits a short trip that stays in the busier parts of the country. Speeds are carrier-dependent. Prices checked August 15, 2026.
Pros
- Plans in 200-plus destinations on one eSIM
- One install can cover Indonesia plus other Southeast Asia stops
- Free airport lounge access on a 60-plus minute delay
Cons
- Data-only, no calls or SMS
- Often runs on the 3 (Tri) network, weaker outside Bali
Best for: A cheap trial, or Indonesia as one stop on a wider Southeast Asia route.
Indonesia eSIM prices we checked
Real prices captured August 14, 2026 from eSimania, eSIMDB and Airalo. Prices change often, so confirm the current plan before buying. Speeds depend on the local carrier.
| Plan | eSimania | Airalo (Indotel) |
|---|---|---|
| 1 GB | about $2.40 (7 days) | about $4.50 (3 days) to $8.50 (7 days) |
| 5 GB | about $9.00 (30 days) | about $12.00 (7 days) to $13.50 (30 days) |
| 10 GB | about $13.50 (30 days) | about $21.00 (30 days) |
| Data model | Fixed data, seven Indonesia plans to 50 GB | Indotel (local 5G) plus Asialink (regional) and daily-unlimited options |
Honest note: eSimania is the cheapest here on every size, so there is no Airalo price win to flag; we still do not link to Airalo. Airalo local Indotel plan runs on 5G and is a fine option if you prefer it. Saily and Nomad also list Indonesia; ratings and prices are quoted from those sources.
How much data you need in Indonesia
Coverage: the tourist hubs are easy, the outer islands are not
Indonesia now has three mobile network groups, not four or five, and both mergers that got it there were approved by the government within the last few years. In January 2022 the communications ministry approved the merger of PT Indosat and PT Hutchison 3 Indonesia, the operator sold as Tri, into PT Indosat Ooredoo Hutchison. Then on April 17, 2025 the Ministry of Communication and Digital Affairs, Komdigi, approved the merger of XL Axiata, Smartfren and Smart Telecom into a single entity, PT XL Smart Telecom Sejahtera Tbk. So if a guide lists Telkomsel, Indosat, XL, Tri and Smartfren as five choices, four of those five are now two companies. Source: Komdigi, merger approval.
Those approvals came with coverage conditions, which is the part that matters if your route goes past the tourist hubs. Komdigi required the merged XL and Smartfren business to raise download speeds by 16 percent by 2029 and to add 8,000 new base stations focused on areas that are currently underserved, with the stated priority being Indonesia's 3T regions, the underdeveloped, frontier and outermost areas. The 2022 Indosat and Tri approval carried its own condition: extending mobile service to at least 7,660 additional villages and subdistricts by 2025. Neither promise is a guarantee you will have signal on a given beach, but both tell you where the building is being pointed.
In practice Bali, Jakarta and the main cities are comfortable on any of the three, and coverage still falls off once you leave the hubs, so places like Komodo, the Gili Islands and inland Sumatra can be thin whichever network you land on. Because the marketplace does not name the carrier, download offline maps for the quieter spots rather than trying to pick a network you cannot choose anyway. Prices checked August 15, 2026.
It helps to be precise about what the gap actually is, because the national picture is better than most guides suggest. Indonesia's Ministry of Communication and Digital Affairs, Komdigi, reported in October 2025 that 4G availability had passed 90 percent on every one of Indonesia's large islands. Java led at 96.4 percent, Bali and Nusa Tenggara followed at 95.2 percent, and regions that used to be written off, Sulawesi and Maluku among them, had also crossed 90 percent. Source: Komdigi, Prices checked August 15, 2026.
So the question for a visitor is not whether Indonesia has 4G. It does, nearly everywhere people live. The question is which network reaches the specific places tourists go that people do not live in: a boat crossing, a volcano trail, a cliff on a small island. That is where the operators separate, and where Telkomsel's advantage sits. The independent measurement firm Opensignal again gave Telkomsel the outright coverage award in its July 2026 Indonesia report. Availability statistics measured across a population will not tell you about the trail you are on.
Frequently asked questions
How much eSIM data do I need for Indonesia?
For a typical week or two in Indonesia, 5 to 10 GB covers maps, ride-hailing, messaging, translation and plenty of photos, since many travelers stay a while. Hotels and cafes usually have wifi, so lighter users can manage on 3 to 5 GB, while anyone streaming, working remotely as a digital nomad or tethering should choose a larger plan.
Will an eSIM work in Indonesia?
Yes, if your phone is eSIM-capable and carrier-unlocked. Indonesia is well covered in the cities and tourist hubs, and travel eSIMs run on one of the three Indonesian network groups: Telkomsel, Indosat Ooredoo Hutchison or the merged XL and Smartfren business. Install the eSIM from its QR code before you fly and switch it on when you land at Jakarta or Denpasar.
Which eSIM is cheapest for Indonesia?
eSimania is the cheapest we found on every size, at about $2.40 for 1 GB over 7 days, $9.00 for 5 GB and $13.50 for 10 GB, all under Airalo's local Indotel plan. Jetpac is the one-install option across borders but tends to run on the 3 network, best around Bali. Compare before buying.
Which Indonesia network is best for tourists?
Indonesia has three network groups: Telkomsel, Indosat Ooredoo Hutchison, which absorbed Tri, and the merged XL and Smartfren business that Komdigi approved in April 2025. Komdigi tied that approval to 8,000 new base stations aimed at underserved areas. Bali, Jakarta and the main cities are fine on any of them; Komodo, the Gili Islands and inland Sumatra can be thin on all of them, so download offline maps.
