How to Get an eSIM for Bali (Indonesia)
Everything you need to get connected in Bali: which eSIM to buy, how to set it up before you land, and how much data your trip actually needs.
Quick answer: Buy your Bali eSIM before departure, install it on Wi-Fi, and activate it the moment you land at Ngurah Rai — most plans connect automatically within seconds. Nomad eSIM runs on Telkomsel, Indonesia's widest network, which matters most for coverage beyond the main tourist areas such as Nusa Penida, the Gilis, Lombok.
Do you actually need an eSIM for Bali?
Three ways to get connected in Bali: your home carrier's roaming, a local Indonesian SIM, or a travel eSIM.
- Roaming is the easiest but usually the most expensive — often $10–15 a day once you leave a home-network agreement.
- Local SIM (Telkomsel prepaid, widely sold at the airport and at Indomaret/Alfamart stores) is genuinely cheap, but means swapping out your home SIM and navigating setup in Indonesian.
- eSIM sits in between: set it up before you fly, keep your home number active in a second slot, and activate on arrival without an airport queue.

Quick Bali eSIM provider comparison
Prices based on publicly listed plans as of August 2026 — verify before purchasing, as eSIM pricing changes frequently.
Nomad and Airalo are close on entry pricing, but Nomad's fixed-data plans undercut Airalo from 5GB upward and its unlimited tiers are cheaper at every duration. Holafly's unlimited-only structure suits very heavy daily users, but the 500MB hotspot cap is a real constraint if you're sharing a connection across a group or tethering a laptop from a villa.

Step-by-step: setting up your Bali eSIM
- Check your device is eSIM-compatible. Most 2019+ iPhones (XS and newer), Samsung Galaxy S20+, Google Pixel 3a+, and most flagship Android phones from 2022 onward support eSIM. Run your exact model through the Nomad eSIM device compatibility checker — carrier-locked phones can't install a third-party eSIM regardless of model.
- Buy your plan 1–2 weeks ahead. Since Nomad's validity starts from first use rather than purchase date, there's no downside to buying early and one less thing to sort out on arrival day.
- Install the eSIM on home Wi-Fi. Scan the QR code (or use the app's one-tap install) before you leave — this takes under five minutes and avoids relying on patchy airport Wi-Fi.
- Confirm the profile is active. Toggle to eSIM-only briefly to make sure it shows up correctly in your device settings, then switch back.
- Land and activate. Once you land in Bali, turn on the eSIM line and it connects automatically to the strongest available network — no manual APN configuration needed on most devices.
- Top up in-app if you run low. No new QR code or repurchase — just add data from inside the app.

Bali coverage, area by area
Bali's tourist hubs are well covered by every major provider — the differences show up once you leave them.
Nomad eSIM connects through Telkomsel, which makes the biggest practical difference if your itinerary includes island-hopping beyond the main Bali strip.
How much data do you need for your Bali trip?
A few Bali-specific habits worth factoring in: Gojek and Grab run in the background constantly and need a live connection even though they're light on data; Google Maps holds up well around Seminyak, Canggu, and Ubud but is worth downloading offline before heading to Nusa Penida or the Gilis; and WhatsApp is the default way locals and drivers communicate, so it's worth having set up before you land.
Frequently asked questions
Does eSIM work on Nusa Penida and the Gili Islands?
Yes, but coverage is less consistent than in Bali's main tourist areas. Telkomsel-based plans (including Nomad) perform most reliably on these islands. Download offline maps before any ferry crossing as a backup.
Can I keep my home number active with a Bali eSIM?
Yes — Nomad's Indonesia eSIM plans are data-only and run in dual SIM mode alongside your physical SIM, so calls, SMS, and two-factor authentication on your home number keep working.
Should I buy an airport SIM or set up an eSIM before I fly?
Telkomsel prepaid SIMs are sold at Ngurah Rai Airport and at convenience stores across Bali, and they're cheap. The trade-off is losing your home SIM slot and navigating setup on arrival. An eSIM lets you set up before departure and activate the moment you land, without a counter queue.
How much does it cost to top up mid-trip?
Top-ups happen directly in the app — no new QR code, no new plan purchase, done in under a minute.
Do I need to check my phone's compatibility before buying?
Yes. Not every phone supports eSIM, and carrier-locked phones can't install a third-party eSIM even if the model otherwise supports it. Check with the Nomad device compatibility checker first.
Is eSIM cheaper than roaming in Bali?
Usually significantly. Home-carrier roaming often runs $10–15 a day, while a 10GB/30-day Indonesia eSIM plan costs a fraction of that for the whole trip.
