If you are planning a trip to Indonesia, being prepared with the right practical information will help ensure a smooth and enjoyable holiday. Drawing on our two decades of experience creating tailor-made journeys in Asia, we’ve gathered key details every traveler needs to know for a seamless adventure across the archipelago.
Electrical outlets
In Indonesia, the power supply is rated at 230V and 50Hz, similar to the standards used across continental Europe. The predominant plug types are type C (two round pins, commonly known as the Europlug) and type F (two round pins with earth clips). Some accommodations, particularly in international hotels, may occasionally offer type G sockets (three rectangular pins), but this is far less common.
What this means for your devices
- European travelers: Your plugs (types C and F) will fit seamlessly into local sockets without an adapter, provided your devices support 220-240V.
- Travelers from the US/Japan: You will likely need a plug adapter and, for devices not rated for 220-240V, a step-down voltage converter to avoid damaging electronics. Look for devices labeled "Input: 100-240V, 50/60Hz"—these are dual-voltage and only require a simple adapter.
- Universal travel adapters covering C and F are a highly practical investment.
Practical advice
- Bring a torch or headlamp: Power cuts, known locally as “mati lampu,” can occur with little warning and may last from a few minutes to several hours, especially on smaller islands or more remote areas. Having a torch in your bag saves you from any unwelcome surprises during the night.
- Portable chargers: With intermittent power and all your travel memories on your phone, a power bank will ensure you’re always able to capture the magic of Indonesia.
- Adapters at accommodations: Upscale hotels in Bali and major tourist areas often provide adapters for guests, but we advise bringing your own for peace of mind.
- Sensitive devices: The frequency in Indonesia is 50Hz—some timing-dependent devices from 60Hz countries may not work properly. Double-check if this could affect any critical electronics you carry.
Currency
Indonesia’s national currency is the Indonesian Rupiah (IDR). It’s best known for its modest value and large denominations, which means you will quickly become used to working with notes in the tens or hundreds of thousands.
Cash or card?
While you’ll find card payment widely accepted in cities, upscale hotels, and many restaurants, cash is king in smaller towns, markets, rural areas, and especially for taxis, temple donations, and street food. Always carry smaller notes—vendors often lack change for large bills, and tips are usually given in cash.
Exchanging and withdrawing money
- ATMs are common in urban centers and most tourist destinations, dispensing 50,000 or 100,000 IDR notes. Typical withdrawal limits per transaction range from 1.5 to 3 million IDR (~100-200 euros), but you may withdraw up to 6 million IDR daily, depending on your home bank’s caps.
- Tips for ATM use:
- Use well-lit, secure ATMs located inside banks or shopping malls.
- Choose to be debited in Rupiah rather than your home currency to avoid inflated exchange rates (“dynamic currency conversion”).
- Some ATMs dispense cash before returning your card—be sure to retrieve your card before you leave.
- Always notify your bank before departure to avoid card blockage due to foreign transactions and check fee structures for international use.
- Currency exchange offices (official “Authorized Money Changers”) offer better rates than airports or banks. Avoid informal or unlicensed changers—even in tourist hotspots—and always count your money before leaving the counter.
- Pro travel tip: Ask your Shanti Travel Expert or your local driver for recommended places to change money safely.
Payment customs
- Most card transactions are subject to a bank fee or surcharge of 2–3%.
- In smaller shops and for most excursions, guides prefer to be paid in Rupiah.
- Keep receipts and if possible, access up-to-date rates through trusted currency apps before making exchanges or large purchases.
Telephone & connectivity
Staying connected in Indonesia is straightforward if you arrive well-prepared:
SIM cards and local operators
- Local prepaid SIM cards from leading providers—Telkomsel, XL Axiata, Indosat Ooredoo—offer excellent coverage, with Telkomsel especially reliable in remote and rural areas. 4G service is common even on smaller islands.
- Purchase a SIM at the airport, in major towns, or through your Travel Expert (who may provide one in Bali). Plans typically start at IDR 10,000–50,000 and offer various options from 5-25 GB per month, suitable for both moderate and heavy users. For seamless activation, carry your passport and make sure your phone is unlocked.
- eSIMs are available but less common, with fewer data options and primarily offered by Telkomsel in major arrival airports.
- By law, visitors must register their SIM card using their passport and phone IMEI.
Top-up & usage
- SIM cards allow local and international calls, mobile data, and can be topped up in telecom stores, convenience shops, or via mobile apps.
- You can use your phone as a personal hotspot—very useful if traveling with a laptop or tablet.
- If your SIM runs out of credit, topping up is quick and widely accessible online or in mini-markets everywhere.
Internet access
- Wi-Fi is widespread in hotels, cafes, and many public spaces in tourist areas. However, cellular data provides greater reliability for on-the-go navigation or communication.
Before you leave home
- Ensure your device is unlocked for use with Indonesian SIM cards. Have your phone’s IMEI handy for SIM activation at point of sale or with your local guide.
At Shanti Travel, we advise all travelers—especially those visiting off-the-beaten-path destinations across Indonesia—to secure a reliable means of communication and be prepared for occasional technological challenges. This ensures your journey across Indonesia is as carefree and immersive as it should be, whether you’re exploring volcanic landscapes, remote beaches, or vibrant city streets.
