The best eSIM for Bali and Indonesia
Data in Bali and Indonesia currently starts at $1.7 a gigabyte — that's 20GB for $34, valid 15 days. Below is what each provider actually charges, and the fine print that decides whether the cheap one stays cheap.

Why Bali and Indonesia is different
Bali runs on scooters and Google Maps, and the island's addressing is famously vague — villa directions are frequently a pin rather than a street number. Navigation is the dominant data use here, not streaming, and it is the thing that breaks worst when a plan throttles. Indonesia is also spread across thousands of islands, so coverage varies far more than a single country page suggests.
If you are island-hopping to Lombok, the Gilis or Nusa Penida, expect real coverage gaps on the water and on the smaller islands. Download offline maps before you leave Bali. A metered plan with a decent allowance beats an unlimited pass here, since throttled data still loads maps but a dead plan does not.
What 10GB costs in Bali and Indonesia
Normalised to cost per gigabyte, because bundle sizes differ between providers and headline prices are not comparable. Airalo's figure recalculates daily from its live catalogue; the others were read by hand on 20 July 2026.
| Provider | Best value plan | Per GB | Throttled after |
|---|---|---|---|
| Airalo live pricing | 20GB · 15 days · $34 | $1.7 | 3 GB/day, then 1 Mbps |
| Holafly | Unlimited · 30 days · $73.9 | n/a — sold by day, not by GB | Not published; hotspot capped at 1 GB/day |
Currencies are as each provider quoted them and are not converted — Yesim and Saily geo-detect, so you may be shown a different one. Full fine print for every provider is on the main comparison.

Before you buy
Don't activate it until you land
Most plans start counting down when the eSIM first connects to a network at your destination, but some activate on installation regardless of where you are. Install the profile before you fly by all means — just leave the line switched off until you arrive, or you can lose days off a short trip before it starts.
Your bank texts won't arrive on it
These are data-only plans with no phone number, so SMS one-time codes from your bank or airline will not reach them. Move two-factor codes to an authenticator app before you travel, keep your home SIM active for texts with data roaming switched off, and turn on Wi-Fi calling.
Buy smaller and top up
Every provider here forfeits unused data at expiry — there is no rollover and no refund. Buying a modest allowance and topping up beats over-buying, though check top-ups are supported first: Airalo only offers them on plans marked rechargeable, and Holafly has withdrawn them entirely.
Check your phone is eSIM-capable and carrier-unlocked before buying. A locked handset will not accept the profile, and that is the single most common reason these fail on arrival.
