SIM Cards, Apps & Emergency Numbers
Telkomsel vs travel eSIMs, the new face-scan SIM rules, dead zones, 112, and the apps that run Bali
Getting online in Bali is cheap and easy, but 2026 rewrote the rules: new SIMs now require biometric registration, so a few minutes of planning saves real hassle. First, the numbers that matter most.
EMERGENCY NUMBERS — save these before you need them: - 112: all emergencies, island-wide, free, works from any local SIM even with zero credit - 110 police, 113 fire, 118 or 119 ambulance - 115 BASARNAS sea and mountain rescue (Bali office +62 361 752 222 — surfers, hikers, boat trips) - Bali Tourist Assistance Centre: +62 361 224 111 The 3-digit numbers dial from any Indonesian SIM but may not connect from a foreign roaming SIM — the +62 361 landlines are your roaming-safe fallback.
SIM vs eSIM. For trips up to two weeks, a travel eSIM installed before you fly is cheapest and has you online at baggage claim: as of mid-2026, Airalo's Indonesia plans start at USD 4.50 for 1GB, with 10GB/30 days around USD 22-26 (airalo.com). The catch: Airalo runs on Indosat and 3, not Telkomsel — fine for Canggu–Seminyak–Ubud, patchy in east Bali and on Nusa Penida. For longer stays or anywhere beyond the south, buy Telkomsel: the official Tourist Prepaid Card is IDR 150,000 (about USD 9) for 25GB plus 25 minutes of calls, valid 30 days, sold at Ngurah Rai airport counters and GraPARI stores (telkomsel.com/perdana/tourist-prepaid-card). Local resellers also sell Telkomsel-network eSIMs online for around USD 12 per ~24GB — cheap and well-covered. Skip third-party airport kiosks: they charge roughly double town prices (USD 15-30 vs 7-15) for the same data. The official Telkomsel card is your fair-price benchmark on arrival.
Registration — the new part. Since 1 July 2026, every new Indonesian SIM is sold inactive and only activates after face-scan registration against your passport. Buy at official counters (airport kiosks, GraPARI, XL Center), where staff run the 1-2 minute check; the old grab-a-ready-SIM-from-a-minimart trick no longer works, and you're capped at 3 numbers per operator per passport. Keep your home-number eSIM active alongside the local one — WhatsApp on your home number is how every villa, driver, and tour operator will contact you, and your banking codes need it too.
Staying over 90 days? Registering a tourist SIM automatically whitelists your foreign phone's IMEI for 90 days, free — shorter visits need do nothing. Beyond that, declare the phone (you'll register it on the All Indonesia arrival card — see the Visas & Entry Requirements guide) and register the IMEI at the airport customs desk when you land. Airport registration is free for devices worth up to USD 500. Do it later at a customs office (possible until day 60, impossible after) and you lose that exemption and pay tax on the full device value — roughly 40% above the threshold.
Coverage reality: Telkomsel works essentially everywhere; every carrier has gaps around Sidemen and the Mt Agung slopes, the Bedugul–Munduk lake roads, parts of the Kintamani rim, the north coast between Lovina and Pemuteran, and West Bali National Park. 5G exists only in south-Bali urban pockets — Uluwatu is still 4G. Download offline Google Maps for the mountains and east, and never rely on hotel Wi-Fi for anything time-sensitive: power cuts take routers down island-wide, so a data plan with hotspot allowance is your backup.
Apps to install: Gojek and Grab for rides, food, and payments (both work fine, with designated airport pickup zones), MyBluebird for metered taxis where app pickups are restricted, WhatsApp for every booking, Google Maps plus Waze for traffic, Google Translate with the Indonesian offline pack and camera mode for menus, and the official All Indonesia (arrival card) and Love Bali (tourist levy) apps.
Bottom line: install a travel eSIM before you fly or buy the Telkomsel Tourist Card at an official counter with your passport, choose Telkomsel if your plans leave the southern strip, and save 112 and +62 361 224 111 right now.
