Does any eSIM work on all of Indonesia's islands?

No. In the main tourist areas like Bali, most eSIMs work without any issues. But on the more remote islands, coverage depends heavily on the carrier being used. That's why it's best to pick a multi-network eSIM that supports Telkomsel.

Which is the best mobile carrier in Indonesia?

Overall, Telkomsel is considered the carrier with the widest coverage. It tends to offer more reliable mobile data than the others, especially on remote islands and in rural areas.

How much data is enough for Indonesia?

If you'll mostly be using maps, messaging and light browsing, a few GB is usually plenty. If you plan to watch video, share a hotspot, or spend a long time hopping between islands, it's better to go for a larger package.

Will the eSIM work on the Gili Islands, Komodo or Raja Ampat?

Multi-network eSIMs that support Telkomsel work across most inhabited areas. That said, in very remote spots the signal can weaken on every carrier. For trips like these, it's a good idea to download offline maps in advance.

Which eSIM works best on Indonesia's remote islands?

LSThe LimitSim team

Indonesia is made up of more than 17,000 islands. In popular tourist areas like Bali, just about every network works fine, but the moment you head somewhere more remote — Lombok, the Gili Islands, Komodo, Flores, Raja Ampat, Sulawesi or the far corners of Sumatra — the carrier your eSIM uses can make a huge difference.

Plenty of travellers set off with an eSIM that runs perfectly in Bali, only to hit a weak signal or no internet at all once they move on to other islands. Here's what to look for when choosing an eSIM so that doesn't happen to you.

Why does the carrier matter so much?

In Bali and the other major tourist hubs, mobile coverage is generally solid. But the further out you go, the bigger the gaps between carriers become.

This is especially true in destinations like:

Lombok
the Gili Islands
Komodo
Flores
Raja Ampat
Sulawesi
parts of Sumatra

In these areas, Telkomsel is widely considered the carrier with the broadest coverage and the most reliable mobile data. Some other networks can be patchy here, or give you no signal at all.

That's why an eSIM tied to a single carrier is a risky choice. You could end up with no connection at the exact moment you need the internet most.

What should you look for in an eSIM for Indonesia?

The best option is an eSIM that:

supports more than one local carrier;
works on the Telkomsel network.

When it does, your phone can switch between the supported networks depending on what coverage is available, which makes it far less likely you'll be left offline in a remote area.

LimitSim's Indonesia plans support the main local mobile networks, including Telkomsel. That means you're never locked into just one carrier.

What should you do before your trip?

Before you leave for Indonesia:

choose a data plan that suits your trip;
install the eSIM ahead of time over a stable Wi-Fi connection;
turn on Data Roaming for the eSIM line.

This is completely normal for travel eSIMs and doesn't trigger any extra roaming charges.

If you're planning to island-hop across several destinations, it's smart to go for a larger data package. That way you won't have to buy a new one in a weak-signal area the moment your data runs out.

And if you run into any trouble getting connected, our support team is here to help.
