And The Best eSIMs for Travelling Indonesia Are...

According to Wikipedia and ChatGPT, most travellers spend just over a week in Indonesia. But if you’ve ever fallen down a Reddit rabbit hole, you’ll see plenty of people saying even 30 days isn’t enough once you start planning.

With world-famous destinations like Bali, Komodo, Jakarta, and Raja Ampat, it’s easy to see why.

No matter how long you're staying, staying connected is key—whether it's for navigating remote islands, booking last-minute flights, or sharing those unreal beach sunsets on Instagram. That's where eSIMs come in, offering a hassle-free way to ditch the physical SIM card and avoid insane roaming fees.

So, which eSIM is best for Indonesia?

Best travel eSIM for Indonesia

Local providers like Indosat Ooredoo Hutchison (IM3) and Telkomsel offer their own eSIM plan selections, but they require a store visit to get activated. So we rounded up the top international eSIM providers to help you pick the right plan and connect instantly—whether you're here for a week, a month, or contemplating a permanent move after your first Nasi Goreng.

And since many travellers visit Indonesia as part of a longer trip, we’ve included a global plan (Three) to keep you connected wherever you go.

Holafly is another popular option, boasting unlimited data and extensive coverage. Just make sure you check their reviews and fair usage policy, as speeds can get throttled once you reach a daily threshold. And it’s pricier than other eSIMs on this list—a 30-day plan costs $75.

When to activate your eSIM

Timing is everything! Ideally, you should activate your eSIM just before you leave or as soon as you land in Indonesia. Most eSIMs start counting from the moment they connect to a network, so activating too early might waste precious days. No one wants to lose data before they even hit the beach!

How to activate Your eSIM

Activating an eSIM is as easy as scanning a QR code or downloading an app—literally. Once you purchase your eSIM, you’ll receive instructions and (maybe) a QR code. Then you'll be guided through a few changes in your phone settings. Follow the prompts and (BOOM!) you’re connected—no fumbling with tiny SIM trays or losing your physical SIM in the airport lounge.

Is my phone compatible?

Before you dive into the eSIM life, double-check that your phone actually supports eSIMs. Most newer iPhones (XR and later) and high-end Androids (Samsung S20+, Google Pixel 4, etc.) are good to go. If you're rocking an older or budget phone, a quick Google search (or checking in Settings > About Phone) will tell you if your device is eSIM-ready. If not… well, maybe it’s time for an upgrade? Check this list of compatible models if you're not sure.
