SIM Cards, Mobile Data, and Internet in Indonesia

How to get connected in Indonesia: local SIM cards, mobile data plans, eSIM options, WiFi quality, and what to expect across cities and remote areas.

4 min read

Getting connected in Indonesia is straightforward in cities and tourist areas, less so in remote regions. The mobile network is fast and reasonably-priced, multiple competitive carriers operate, and 5G is rolling out in major centres. WiFi is widely available but variable in quality. This guide covers what to expect and how to set up.

Mobile networks

Indonesia has four main carriers with national coverage:

  • Telkomsel: state-controlled, largest network, best coverage especially in rural areas, slightly more expensive
  • Indosat Ooredoo Hutchison (formerly two carriers, merged in 2022): second-largest, good urban coverage, competitive pricing
  • XL Axiata: third-largest, popular with younger users, good urban coverage
  • Smartfren: smallest, urban-focused, cheap data

For visitors:

  • Telkomsel is the safest choice if you'll travel widely (best rural coverage including remote islands)
  • Indosat or XL are good if you'll stay in cities and tourist areas (cheaper data)

Getting a SIM card

At the airport: Telkomsel, Indosat, and XL all have kiosks at major arrival halls (Bali, Jakarta, Surabaya). Convenient but expensive (often 50-100% above shop prices).

In town: any small mobile shop or kiosk will sell SIMs. Telkomsel has dedicated GraPari stores in shopping centres.

Registration: Indonesian law requires SIM registration with your passport since 2018. The shop will do this; bring your passport.

Costs (approximate):

  • SIM card itself: free or Rp 10,000-50,000
  • Telkomsel tourist plan: Rp 150,000-300,000 for 7-30 days with 5-30 GB
  • Indosat or XL similar: Rp 100,000-250,000 for similar plans
  • Per-month topup: Rp 100,000-200,000 for 5-20 GB depending on carrier

The carrier apps (MyTelkomsel, MyIM3, MyXL) are useful for monitoring usage and topping up. They accept Indonesian bank cards and e-wallets.

eSIM

eSIM support is now available with all major carriers (since 2023). For travellers with eSIM-capable phones (iPhone 11+, modern Pixel and Samsung), this avoids the physical SIM swap.

Options for eSIMs:

  • Direct from carrier: visit a Telkomsel/Indosat/XL store with your passport
  • International eSIM providers: Airalo, Holafly, Ubigi, GigSky offer Indonesia eSIMs that work pre-arrival but at higher cost (USD 15-40 for 5-10 GB)

For longer stays the direct carrier route is cheaper; for short trips the international eSIM is more convenient.

Network quality

4G is universal in cities and tourist areas. Speed expectations:

  • Urban: 20-80 Mbps typical, sometimes higher
  • Tourist areas (Bali, Yogyakarta): similar to urban
  • Smaller cities and towns: 5-30 Mbps
  • Rural Java, Sumatra, Sulawesi: 5-20 Mbps where coverage exists
  • Remote islands (Raja Ampat, Komodo): 3G if anything; expect significant dead zones

5G has been rolling out in Jakarta, Surabaya, Bali, and Medan since 2022. Coverage is patchy but expanding.

WiFi

Hotel and accommodation WiFi varies widely:

  • 5-star resorts: usually excellent (50-200 Mbps), sometimes free, sometimes with fees for premium speed
  • Mid-range hotels: usually adequate (10-50 Mbps), free
  • Guesthouses and homestays: variable (2-30 Mbps), free
  • Hostels: usually OK but often slow due to many users

Cafe WiFi in tourist areas is widely available and usually adequate for browsing and video calls. Cafe wifi quality benchmarks:

  • Canggu (Bali) digital-nomad cafes: 30-100 Mbps, reliable
  • Ubud cafes: 20-50 Mbps, variable
  • Jakarta CBD cafes: 20-80 Mbps, reliable
  • Smaller towns: 5-20 Mbps, variable

Coworking spaces (especially in Canggu and Ubud) usually have dedicated business-grade internet (100+ Mbps with backup connections).

For digital nomads and long stays

If you're working remotely or living in Indonesia for an extended period:

  • Get a local SIM rather than relying on roaming or hotel WiFi
  • Telkomsel is usually the safest choice
  • Coworking membership if you need reliable workspace connectivity
  • Villa fibre internet: many newer Bali villas offer 50-200 Mbps fibre; older properties may have 5-20 Mbps. Ask before booking
  • Backup hotspot: a separate phone with a different carrier provides backup if your main connection fails (this matters more than people realise)
  • VPN: useful for accessing some services that geo-block Indonesia, or for streaming services that aren't available locally

Censored content

Indonesia restricts access to:

  • Pornographic websites: blocked at the carrier level
  • Some gambling sites
  • Tumblr, Reddit, Vimeo: blocked periodically (status varies)
  • Some VPN services: blocked periodically (status varies)

A reliable VPN (NordVPN, ExpressVPN, ProtonVPN) bypasses most of this. Indonesia has not aggressively pursued VPN users.

Useful apps

For visitors:

  • WhatsApp: the dominant messaging app; restaurants, drivers, hotels often communicate via WhatsApp
  • Grab and Gojek: ride-hailing, delivery, payments
  • Google Maps: works well; Maps.me as offline backup
  • MyTelkomsel / MyIM3 / MyXL: depending on your carrier
  • OVO, GoPay, DANA, ShopeePay: e-wallets for QRIS payments
  • Klook: for activity/ticket bookings
  • 12Go: for inter-city transport bookings

Practical tips

  • Pack an unlocked phone — Indonesian SIMs won't work in carrier-locked phones from countries like the US
  • Get the SIM in person on arrival day if possible — avoid roaming charges
  • Top up before long trips — rural data top-ups are sometimes hard
  • Carry a power bank — Indonesia's electricity is generally reliable but you'll be away from sockets often

For a typical 2-week Indonesia visit, a single Telkomsel SIM with 20 GB plan (about USD 12-15) handles all communication and navigation needs comfortably.
