Indonesia Good to Know

Upload Photo     Upload Video

Keeping in touch with the outside world from Indonesia is rarely a problem, at least if you stay anywhere close to the beaten track.

Telephone calls

As getting a fixed line remains an unaffordable luxury for many Indonesians, wartel (short for warung telekomunikasi) can be found on most every street in Indonesia.

If you have Global System Mobile (GSM) cellular phone, ask your local provider about "roaming agreement/facility" with local GSM operators in Indonesia (ie: PT Indosat, PT Telkomsel, PT Excelindo etc).

  • Making local calls: Dial (telephone number)
  • Making long distance calls: Dial 0-(area code)-(telephone number)
  • Making international calls: Dial 017-(country code)-(area code, if any)-(telephone number)
  • Beside "017" prefix, you can use "001", "007" or "008". For example: 001-(country code)-(area code, if any)-(telephone number)
  • You can make International calls through operator: dial 101 or 102.
  • Making long distance collect calls: Dial 0871-(area code)
  • Connecting to the Internet: Dial 080989999 (from your modem), costing you Rp. 165/minute in business days and Rp. 100/minute in Saturdays and Sundays
  • TELKOM Calling Card access number: Dial 168

Mobile phones

The Indonesian mobile phone market is heavily competed and prices are low: you can pick up a prepaid SIM card for less than Rp 20,000 (US$ 2) and calls may cost as little as Rp 1,000 a minute (subject to the usual host of restrictions). SMS service is generally very cheap, with local SMS as low as Rp.100-150, and international SMS for Rp.400-600. Indonesia is also the world's largest market for used phones and basic models start from Rp 200,000.

The largest operators are Telkomsel (brand Kartu HALO, simPATI, Kartu As), Indosat (brands Matrix, Mentari, IM3), 3 AXIS and Excelcomindo (brands Jempol, Bebas). In general Telkomsel has the best coverage, especially in remote places, while the other three are slightly cheaper; on Java and Bali, any will work just fine.

If you have Global System Mobile (GSM) cellular phone, ask your local GSM operator about "roaming agreement/facility" in Indonesia. Most GSM operators in Indonesia have roaming agreement with various GSM operators worldwide. Using roaming facility, you can use your own cellular phone and GSM SIM card in Indonesia But, of course, this means you will pay several times more than if using local SIM.

Most Indonesian operators use GSM, but beware of the few offering CDMA phones: they are slightly cheaper, but generally not usable outside major cities. Be sure to double-check when buying!


The modern-day version of the wartel is the warnet, which feature Internet-connected PCs as well, and many shops now do double duty. Prices vary considerably, and as usual you tend to get what you pay for, but you'll usually be looking at around Rp 5,000 per hour. In large cities, there are free hotspots in certain shopping malls, McDonald restaurants and StarBucks cafes. Some hotels provide free hotspots in the lobby.

If you have GSM/WCDMA Mobile phones, you can easily use them for internet connections with most prepaid cards with the major operators. Packet-based and unlimited monthly/weekly/daily packages are both available (the latter are becoming more popular), and the available deals and combinations change constantly. The best way to know current deals is to visit operators' websites (generally in Indonesian only, so you may need to use a service like Google Translate), or to ask dealers selling SIM cards.

As of August 2010, Rp.100,000-200,000/month (or from Rp.10,000/day)will get you unlimited Internet on Telkomsel, Indosat or XL, with maximum speeds varying from 256 kbit/s to 2 Mbit/s in 3G covered areas — although in practice often much less due to congestion, and the highest speeds are only available in the main cities and tourist destinations. Despite the claims of various dodgy airport shops, you do not need to buy a modem bundle to use these packages with your phone.
