Temples, surf beaches and rice terraces on one island
Overview
Buy a Bali eSIM before you board and you will have data the moment you land at Denpasar — no airport counter, no tourist markup. Plans cost about IDR 90,000–180,000 ($5–$10) for 5–10 GB over a week, while typical daily roaming packs from home carriers cost more than that per day.
In Bali you will use data constantly: Gojek and Grab bookings, driver WhatsApp chats, Google Maps on scooters. Do not plan around hotel Wi-Fi alone.
| Option | Good for | Rough price |
|---|---|---|
| Indonesia eSIM on Telkomsel (5–10 GB) | The standard Bali trip — best coverage island-wide | IDR 90,000–180,000 ($5–$10) |
| Asia regional eSIM | Bali + Singapore/KL/Bangkok multi-stop trips | IDR 150,000–300,000 ($8–$17) |
| Unlimited Indonesia eSIM | Heavy users, hotspot for a family, long stays | IDR 250,000–450,000 ($14–$25) |
| Local physical SIM from a town store | Non-eSIM phones; cheapest per GB if you know where to go | IDR 60,000–120,000 ($3.50–$7) |
| Airport SIM counter | Last resort — convenient but marked up | IDR 150,000–250,000 ($8–$14) |
Get the Telkomsel-network eSIM for a standard 5–8 day Bali trip. Coverage matters more than price here — cheaper plans on smaller networks tend to fade in Ubud's valleys and on north-coast roads.
Take a regional Asia eSIM if Bali is one stop of several; one plan across Singapore, Malaysia, Thailand and Indonesia beats juggling QR codes at each border.
Buy a physical SIM in a Kuta or Ubud phone shop only if your phone lacks eSIM support — ask for a Telkomsel tourist pack and check the data is activated before leaving the counter.
Skip your home carrier's roaming for anything beyond a 2-day hop; it is the most expensive option by far.
One more tip: download offline Google Maps for Bali and Nusa Penida before your boat and mountain days. Villa and cafe Wi-Fi in Bali is common but slow at peak evening hours, so treat the eSIM as your main connection, not the backup.
Then get planning with the Bali guide and the Indonesia country guide.
Good to know
One that runs on the Telkomsel network — it has Indonesia's widest coverage, and its signal generally holds up in Ubud's valleys and on Nusa Penida's main roads. Plans with 1–2 GB per day cover maps, WhatsApp and Instagram comfortably.
Roughly IDR 90,000–180,000 ($5–$10) for 5–10 GB over 7–10 days. Daily roaming packs from most home carriers cost more than that for a single day, so an eSIM usually pays for itself before you leave the airport.
No — the airport counters at Denpasar charge tourist prices, often IDR 150,000–250,000 ($8–$14) for what costs about half that in town. An eSIM bought before you fly skips both the markup and the queue.
Telkomsel covers Nusa Penida's main areas, though cliff viewpoints and coves have dead zones. The Gili Islands sit on Lombok's networks — coverage exists but tends to slow at peak evening hours. Download offline maps before boat days.
Yes — keep your home SIM active with data roaming switched off, and let the eSIM handle all data. Incoming SMS codes arrive on most carriers without charge, but check your carrier's roaming terms before you fly. This is the standard two-SIM setup for travellers.
