Internet for residents: home fibre, SIMs and staying connected long-term

Home fibre providers, resident SIM registration, postpaid vs prepaid, and backup-connectivity strategy for people who actually live in Indonesia.

The tourist SIM guide covers arrival connectivity; this page is for people living here. As a resident your questions change: home fibre instead of hotspotting, a number that survives years instead of a top-up cycle, and a backup plan for the outage days.

Home fibre

  • IndiHome — the country's dominant fixed-broadband brand (launched 2015, and part of Telkomsel since mid-2023). Widest footprint by far: if only one provider reaches your address, it's usually this one.
  • Alternatives in major cities — several regional and metro fibre ISPs compete in Jakarta, Bandung, Surabaya, Bali and other centres, often with better price-per-Mbps where they overlap. Coverage is street-by-street: the practical move is to ask neighbours and check each provider's coverage tool for your exact address before signing a lease.
  • Installation typically requires your identity document (passport/KITAS) and sometimes a local contact; timelines run days to weeks depending on whether the street is already cabled.

Before renting a villa or house, test the internet at the property at the time of day you'll use it. Listings say "fast wifi"; your video call disagrees. This is the #1 remote-worker regret in Bali.

SIMs for the long haul

  • Registration is mandatory — SIMs are registered against identity (Indonesians use their NIK; foreigners register with passport details). Do it properly at an official store so the number is registered to you: recovering a "helpfully" agent-registered number later is painful.
  • Keep prepaid alive: prepaid numbers expire after the active period runs out — set a monthly top-up reminder, because a dead number takes your banking OTPs and GoPay/OVO access with it.
  • Postpaid plans exist for residents and remove the expiry problem; sign-up needs your stay-permit paperwork.
  • Bringing your own phone? Imported handsets need their IMEI registered with customs to work on local networks beyond the grace period — do it at the airport on arrival (see customs rules).

The backup stack (what long-termers actually run)

  1. Home fibre as primary
  2. A generous mobile-data plan on a second SIM from a different network than your primary
  3. Router that accepts a USB/SIM failover, or simply a phone-hotspot discipline
  4. Know your nearest coworking space for outage days and power cuts

Common mistakes

  • Signing a year's villa lease off a "fast wifi" listing claim without a speed test
  • Letting a prepaid SIM lapse and losing the number your bank OTPs go to
  • Registering your SIM under an agent's identity
  • Skipping IMEI registration and discovering your imported phone goes dark

FAQ

Which mobile network is best? Coverage leadership varies by island and even by village — the pragmatic answer is: whichever network your neighbours use, plus a different one as backup.

Can I get fibre in a rural area? Often no — satellite and fixed-wireless options fill the gap, at meaningful cost. Verify connectivity before committing to remote living.

Is 5G available? In major-city pockets. Plan around good 4G, treat 5G as a bonus.

Verify before acting
