Cheapest unlimited eSIM for Indonesia? From €4.95 for 3 days (October 2026)

Roam2Go’s unlimited eSIM for Indonesia starts from €2.95 for 1 day and is the most practical solution if you want to browse without counting megabytes between temples, rice fields and beaches. In this article you’ll find all the available plans, a table with real prices and essential tips to choose the one that best suits your trip.

Why an eSIM is the best option for Indonesia

Indonesia is an archipelago of thousands of islands, and staying connected can be a challenge if you rely on roaming from your usual network. Traditional roaming charges often work out very expensive for trips longer than a day or two, and buying a local SIM at the airport means queues, forms and, sometimes, language barriers.

With a Roam2Go eSIM you can purchase and set up your plan from home, before you board the plane. No physical cards, no changing your number, and a fixed price in euros with no surprises. Plus, if your phone supports dual SIM, you can keep your regular SIM active to receive calls and texts on your usual number, with data roaming switched off on that line. Since Indonesia is outside the EU, your provider’s voice and SMS roaming is normally switched off by default (if you want it, you have to ask for it) and, if you have it enabled, you may be charged for the calls you make and receive as well as for texts.

Unlimited plans for Indonesia: 3, 5 and 7 days

If your trip is short or packed full —a week in Bali, a route through Java, diving in Lombok— Roam2Go’s unlimited plans are the most convenient choice. Forget about calculating how many GB you use each day: browse, stream maps and upload photos without a worry.

How much does each unlimited plan cost?

• Unlimited / 3 days: €4.95
• Unlimited / 5 days: €6.95
• Unlimited / 7 days: €9.95
• Unlimited / 10 days: €13.95
• Unlimited / 15 days: €19.95
• Unlimited / 30 days: €33.95

The 3-day plan is usually enough for short breaks or for the first few days of a longer stay (while you find your feet and decide whether you need more). The 7-day plan is ideal for a full week without needing to renew anything.

How to choose the right plan for your trip

The choice between unlimited and a GB plan depends mainly on two factors: how long your trip is and how you use your phone.

Go for unlimited if…

• You use Google Maps constantly (especially handy between temples and rural villages in Bali or Java).
• You want to make video calls with family or friends without keeping an eye on your usage.
• You upload content to social media every day.
• Your trip lasts 7 days or fewer.

Go for a GB plan if…

• Your trip lasts 2 weeks or more and your usage is moderate (messaging, occasional maps, basic browsing).
• You spend many hours each day offline (hikes, dives, areas with no signal).
• You’d rather pay less and keep an eye on your usage.

For example, 10 GB over 30 days is usually enough for a month of travel with normal usage. If you’re the type who posts stories every hour, the 30-day unlimited plan may work out better value.

Coverage and speed: what to expect in Indonesia

In the main tourist areas —Bali (Kuta, Seminyak, Ubud, Nusa Dua), Jakarta, Yogyakarta, Lombok— 4G coverage is generally good and more than sufficient for everything a traveller typically needs. In rural areas in the interior of Java or on small, remote islands, the signal may drop to 3G or even be non-existent at certain spots.

If your itinerary involves lots of boat transfers between islands or hikes to remote volcanoes, bear in mind there will be moments without coverage. This is independent of your eSIM provider: it’s simply the reality of the archipelago’s telecommunications infrastructure.

A practical tip: download offline maps of the areas you’ll be visiting (Google Maps or Maps.me) before leaving a zone with coverage.

Activation and setup: simple and quick

One of the main advantages of Roam2Go eSIMs is that you can set everything up from home, at your own pace. The process is straightforward:

1. Purchase your plan on the Roam2Go Indonesia page.
2. Receive your QR code by email within a few minutes.
3. Scan it from your phone’s settings (you’ll need an internet connection to do this, so do it at home or over the hotel Wi-Fi).
4. Activate the plan when you land in Indonesia and you’re all set.

No waiting for a physical card, no need to visit a shop and no manual codes to enter. If you have any questions during the process, the Roam2Go team is on hand to help via chat or email.
