Buy eSIM data plans for Indonesia
Your Indonesia eSIM is a prepaid data plan that connects your phone to local Indonesia networks at full speed the moment you land — a digital SIM you install before you fly, with no queues, no SIM swap and no roaming fees.
An Indonesia eSIM is a data-only SIM that downloads to your phone before you fly and switches on the instant you arrive. Land at Jakarta's Soekarno-Hatta International Airport and you connect straight to local networks 3 (5G) and INDOSAT (5G) without hunting for a SIM kiosk or paying roaming. By the time you reach the taxi rank your maps are loaded, your messages are sending, and your ride is booked. One small QR scan at home means you step off the plane already online across thousands of islands, from the capital to the beaches.

Important cities in Indonesia
Jakarta · City guide
Jakarta
A Jakarta eSIM keeps you oriented in a capital that stretches in every direction. Use mobile data to wander the Kota Tua old town, pull up details on the National Monument, and check transit times before heading to the busy waterfront. With coverage strong in the city centre, you can call a ride and message your group while you cross from one district to the next.
Jakarta eSIM — online before you land →Denpasar · City guide
Denpasar
As the gateway to Bali's beaches, this is where most island trips begin. A data plan for Denpasar lets you browse the traditional markets, map a route to the nearby temples, and share photos as you go. Coverage is reliable around the busier tourist areas, so keep mobile data on to navigate, translate a menu, or check the forecast before a beach day.
Denpasar eSIM — online before you land →Yogyakarta · City guide
Yogyakarta
A Yogyakarta eSIM is built for slow days of sightseeing. Use mobile data to plan an early start for the Borobudur temple nearby, look up the carvings at the Prambanan temple, and read up on the kraton palace before you visit. Connectivity holds well in town, so you can keep messaging home and pulling up directions between each stop without touching a physical SIM.
Yogyakarta eSIM — online before you land →Bandung · City guide
Bandung
With its cool highland setting, this city makes an easy escape from the lowland heat. A data plan for Bandung helps you admire the colonial architecture, find a cafe between sights, and map drives out to the surrounding tea plantations. Coverage is strong in the centre but can thin out as you climb into the hills, so download your route while you still have a solid signal.

Frequently asked questions
Which mobile networks does the Indonesia eSIM use?
It connects to leading Indonesian networks, 3 (5G) and INDOSAT (5G), so where 5G is available your phone uses it and otherwise falls back to fast 4G. The eSIM picks the best available signal automatically, with strong service in city centres and more variable coverage in remote and rural areas.
Will the eSIM work when I island-hop around Bali, the Gili islands and Lombok?
Yes. Coverage is strong across the main tourist areas of Bali, the Gili islands and Lombok, so you can navigate, message and book around the popular spots. Signal can drop on the boats between islands and on remote beaches, so it is worth saving maps and booking confirmations offline before you set off.
Is this enough for a wider Southeast Asia trip?
This is an Indonesia-only plan, designed for travel within the country. If your trip crosses borders into other parts of Southeast Asia, choose a regional eSIM that covers multiple countries instead, so you stay connected without buying a separate plan at each stop.
When should I set up the eSIM before arriving in Indonesia?
Install it over Wi-Fi a day or two before you fly while you still have a stable connection, then leave it ready to activate. That way it switches on automatically when you reach Jakarta's Soekarno-Hatta International Airport, and you are online before you even leave the terminal.
Will my phone work with an Indonesia eSIM?
Most recent phones support eSIM and are sold unlocked, which is all you need. If your device is eSIM-compatible and not locked to a single carrier, you simply scan a QR code to install the plan; older or carrier-locked phones may not support it, so check your settings before you travel.
Can I keep my own number and use a hotspot in Indonesia?
Yes. The eSIM adds data alongside your existing SIM, so your usual number stays active for calls and texts while the Indonesia plan handles mobile data. Most phones also let you share that connection as a personal hotspot, which is handy for a tablet, laptop or a travel companion's phone.
