Indonesia SIM Cards & Internet: Telkomsel, XL & Data Plans

Staying connected in Indonesia is straightforward in major cities and tourist areas but requires some planning for remote islands and jungle areas. This guide covers the best SIM cards, data plans, eSIM options, and what to expect for internet quality across the archipelago.

Should You Buy a Local SIM?

Yes, for any visit longer than a few days. Indonesian data is inexpensive — approximately IDR 100,000–150,000 (roughly USD 7–10) buys a month of data that covers most travellers’ needs. Relying on hotel Wi-Fi alone limits your flexibility significantly, particularly for navigation, Grab/Gojek, and translation.

Best SIM Cards for Tourists

Telkomsel (Simpati / Loop)

Best overall choice. Telkomsel has the widest nationwide coverage in Indonesia — the only operator with reliable signal in rural Bali, remote Lombok beaches, and many of the smaller eastern islands. If you’re planning any time outside the main tourist circuit, Telkomsel is the safe choice.

Data plans as of 2026: Approximately IDR 100,000–150,000 for 20–50GB, depending on the package (called “paket data”). These change regularly — check at point of purchase.

XL Axiata

Strong second choice in Bali and Java. XL offers competitive pricing and good 4G coverage in Bali, Jakarta, Surabaya, and Yogyakarta. Data packages are similar in price to Telkomsel. Less reliable in remote areas.

Indosat Ooredoo Hutchison

Budget option. Cheaper packages than Telkomsel and XL, and adequate coverage in main tourist areas. Not recommended if you’re heading to smaller islands or trekking areas.

Three (Tri)

Good for heavy data users in cities — some plans offer very generous quotas at low prices. Coverage drops off sharply outside urban Java and Bali.

Where to Buy

• Airports: SIM cards are available at dedicated counters in the arrivals hall at Bali (Ngurah Rai), Jakarta (Soekarno-Hatta), and other major airports. Airport prices are slightly higher but very convenient
• Indomaret and Alfamart: The convenience store chains found on every main street across Indonesia — they stock starter packs and top-up credit (pulsa) for all major operators
• Phone shops and electronics malls: Available everywhere; staff can help configure the SIM if needed

What you need: Your passport. SIM registration is required by Indonesian law — operators scan your passport details at point of sale. This takes two to three minutes and is routine.

Data Plan Costs (as of 2026)

Prices are approximate and change regularly:

Operator	Data	Validity	Approximate Cost
Telkomsel	20GB	30 days	IDR 100,000
Telkomsel	50GB	30 days	IDR 150,000
XL Axiata	25GB	30 days	IDR 90,000
Indosat	30GB	30 days	IDR 80,000

Top-up credit (pulsa) is available at Indomaret, Alfamart, and most warungs. You can also top up via the operator’s app or at ATMs. GoPay and other e-wallets accept data package purchases as well.

eSIM Options

eSIMs work in Indonesia and are a convenient option if your phone supports them (most flagship phones from 2020 onwards do — check your device settings).

Airalo is the most widely used eSIM marketplace and offers Indonesia plans from approximately USD 4–10 for 1–3GB, up to USD 25–35 for larger packages. Airalo eSIMs for Indonesia typically run on the Telkomsel or XL network.

Other options include Holafly, Nomad, and Saily. Compare coverage maps for your intended destinations before purchasing.

Advantage of physical SIM: Indonesian local numbers are useful for registering apps (GoPay, Grab, Gojek all require an Indonesian number for full functionality). eSIMs typically provide data only, no local number.

Solution: Some travellers use an eSIM for data and WhatsApp, then buy a cheap local physical SIM for app registration.

Internet Speeds

Bali (Canggu, Seminyak, Ubud): 4G LTE is widely available and fast enough for video calls and large file transfers. Coworking spaces in Canggu and Ubud offer fibre connections with speeds of 50–200 Mbps. Dojo, Outpost, and similar coworking venues are reliable options.

Jakarta: Fast 4G and available fibre in most commercial areas. Some of the fastest mobile data speeds in Southeast Asia in central Jakarta.

Lombok and Gili Islands: 4G available on Lombok main island; the Gili Islands have 4G but at slower speeds, particularly on Gili Trawangan. Expect video calls to be patchy.

Remote and eastern islands: 4G drops to 3G or 2G in many areas. Signal may be intermittent or absent in jungle and rural highland areas. Download everything you need before heading off the main route.

VPN

Some services are blocked in Indonesia, including certain social media platforms during political events (this has occurred historically during elections). A VPN is useful to have configured and working before you arrive. ProtonVPN and ExpressVPN both function reliably in Indonesia.

Using a VPN on public Wi-Fi (cafes, hotels) is good practice regardless of content access concerns.

Offline Maps

Download offline maps before heading to areas with uncertain connectivity:

• Google Maps: download the relevant region offline (works for major cities, Bali, Lombok)
• Maps.me: better for rural and remote areas — more detailed offline coverage for tracks and small roads not on Google Maps
• Organic Maps: open-source alternative, useful for trekking routes

For diving and boating between smaller islands, download maps while on hotel Wi-Fi — you’ll have no connection on the water.

Wi-Fi Quality

Wi-Fi is available in most hotels, guesthouses, cafes, and restaurants across the main tourist areas. Quality varies considerably:

• Budget guesthouses: often slow (5–20 Mbps) and shared across many devices — fine for messaging and light browsing
• Mid-range and above hotels: usually reliable; ask for the router password rather than lobby Wi-Fi if possible
• Cafes in Bali: generally excellent — competing for digital nomad business has driven up speeds

Always use a VPN on shared public Wi-Fi networks. Avoid accessing banking or sensitive accounts without it.
