Bali eSIM & SIM Card for Scooter Riders: Data for Maps & WhatsApp
On a scooter in Bali, your phone is your map, your Grab back-up and your line to the rental if something goes wrong. Getting reliable mobile data sorted before you ride is one of the most useful things you can do. Here’s how.
eSIM or local SIM?
eSIM
- Bought online before you fly, installed with a QR code.
- Works as soon as you land — perfect for messaging your rental from the airport.
- Your phone must support eSIM and be unlocked.
- Usually a little more expensive per GB than a local SIM.
Local SIM card
- Sold at the airport and at official carrier stores.
- Usually the cheapest data and often includes a local number (handy for some apps).
- Requires passport registration. Buy from official counters or stores rather than random street sellers.
Which network?
Indonesia’s big carriers include Telkomsel, XL Axiata and Indosat (IM3). Telkomsel is widely regarded as having the best coverage across Bali, including mountain areas and East Bali. In South Bali and Ubud, all major networks generally work well. Many eSIM providers roam on Telkomsel or another local network — check which one before buying.
How much data do you need?
Navigation and messaging don’t use much. For a typical 1–2 week trip, 10–30 GB is plenty for Google Maps, WhatsApp, Grab and social media. Video calls and streaming use more.
Offline maps for dead zones
Signal drops in some valleys and mountain roads — around Munduk, Sidemen and parts of East and West Bali. Download the Bali area in Google Maps before long rides. More navigation tips in navigating Bali by scooter.
Phone mount and power
- Use a mount — never ride with your phone in your hand. Many rentals provide one on request.
- Carry a small power bank: navigation drains batteries fast.
- Protect it from rain with a zip-lock bag or waterproof case in the wet season.
- Use one earbud at most for directions, so you can still hear traffic.
Apps worth installing
- Google Maps with offline areas downloaded.
- Grab and Gojek — for nights out and back-up rides.
- WhatsApp — how almost every rental, villa and driver in Bali communicates.
Arriving at the airport
If you’re picking up a scooter or car at Ngurah Rai, an eSIM lets you message the rental the moment you land. See Bali airport scooter rental and Bali airport car rental.
