Which eSIM should you buy for Bali? It depends on who is travelling
You land at Ngurah Rai Airport (DPS) after a flight from Delhi, Mumbai, Bengaluru or Chennai, often with a stop in Singapore or Kuala Lumpur. Within twenty minutes you need data for the driver's message, the Grab pickup and the hotel address. A Bali trip looks very different for a honeymoon couple, a family of five and someone working from Canggu for a month, so the right plan differs too.
An eSIM is a SIM built into your phone, so there is no small plastic card to swap. People often call it an eSIM card, though it arrives as a QR code by email, and you scan it with your phone. Olysim has a dedicated Indonesia eSIM page with plans that work in Bali, Lombok and the other islands.
Short answer
For one person on a 6 to 7 night trip, a plan of about 5 GB covers maps, rides, messaging and photo uploads. Choose 10 GB or more if you post videos daily or share data with others. Install it at home on wifi, then switch it on when you land at Denpasar.
Couples and honeymooners: Seminyak, Ubud and Uluwatu
Most couples split five or six nights between the coast and the hills. Your phone does a lot of the work: Google Maps between villages, Grab or Gojek for rides, restaurant reviews and a steady stream of photos to the family WhatsApp group.
That adds up to roughly 400 to 700 MB a day. A 5 GB plan carries you through six days with a margin. If you upload reels every evening, go up to 10 GB.
One local detail: at the sunset Kecak dance at Uluwatu Temple, hundreds of phones share the same tower. Upload your videos later from the hotel, where the connection is steadier.
Families with parents or children
Four or five phones change the maths. You have two ways to handle it. Each adult can carry their own eSIM, or one phone can hold a bigger plan and share it as a hotspot, meaning your phone creates a small wifi network that other phones and tablets join.
The hotspot route suits families who stay together all day, such as Sanur beach mornings and Nusa Dua resort afternoons. Separate eSIMs suit days when the group splits up, say the children at the pool and the adults at a spa in Ubud.
If your parents are less comfortable with phone settings, install their eSIMs for them at home. Our installation guide takes a few minutes per phone, and the line stays switched off until Bali.
Friends sharing a villa in Canggu
Villa wifi serves four people well in the morning and badly at 9 pm, when everyone streams. Give each person a small plan of 3 to 5 GB for the times they are out: cafes around Batu Bolong, beach clubs, scooter rides with Maps running in a phone holder.
Navigation uses little data but plenty of battery. Carry a power bank on scooter days.
Remote workers and month-long stays
Co-working spaces in Canggu and Ubud have good wifi. Cafe wifi is hit and miss, and a failed video call costs you more than the plan does. An hour-long video meeting uses roughly 0.5 to 1 GB, so a month of work calls plus daily life points to 20 GB or more.
Check the number of days on the plan as carefully as the data. A 30-day trip needs a plan that lasts 30 days. Our article on using an eSIM on an iPad or laptop explains how to connect a work laptop through your phone.
| Traveller | Typical stay | Data to plan for | Setup that fits |
|---|---|---|---|
| Couple | 5 to 7 nights | 5 to 10 GB each | One eSIM per phone |
| Family of 4 to 5 | 6 to 8 nights | 15 to 20 GB shared | Hotspot from one or two phones |
| Friends in a villa | 4 to 6 nights | 3 to 5 GB each | One eSIM per phone |
| Remote worker | 2 to 4 weeks | 20 GB or more | Longer plan, hotspot to laptop |
These are estimates based on typical use, so adjust them to your own habits. See the live options and current amounts on the plans page, because prices follow your location.
The first hour at Denpasar airport
International arrivals at DPS can mean a queue of 30 to 60 minutes at immigration when several flights land together. Your phone is useful here. Many visitors need a visa on arrival or an e-VOA, a digital visa applied for online, plus Bali's visitor levy and a customs form that are filled in online.
Save the QR codes and confirmations as screenshots before you fly, and check the current official requirements a few days before departure. Once you are past the baggage belt, switch on your eSIM and order a Grab from the pickup point. You skip the airport SIM counters entirely and head straight to your hotel.
Where the signal gets patchy
Seminyak, Canggu, Ubud, Sanur and Nusa Dua have strong coverage. The hills and islands are less even.
- Mount Batur sunrise treks leave around 2 am, and the signal drops on parts of the trail.
- Nusa Penida, reached by fast boat from Sanur, has weak spots on its cliff roads.
- Munduk, Sidemen and Amed see signal fade between villages.
Download the Bali map for offline use in Google Maps while you are on hotel wifi. It takes a few hundred MB and keeps navigation working when the bars drop. Our guide on which Indian apps work abroad with an eSIM covers the rest of your phone's apps.
How a Bali eSIM compares with Airtel, Jio and Vi international packs
Airtel, Jio and Vi sell international packs in fixed bundles of days and data, usually covering many countries at once. For Bali you probably want something narrower: a plan for Indonesia, with the number of days and the GB you choose.
The fair comparison is cost per GB and number of days. Open the pack in your operator's app, note the data and validity, then place it beside an Indonesia plan that starts from a modest amount on our site. Our piece on eSIM versus physical SIM adds the third option.
If your phone cannot take an eSIM
Olysim also sells a physical SIM, a small plastic card that goes into your phone's SIM tray. It suits older phones and some budget models. Check your model on the eSIM compatible device list before choosing.
A second check is carrier lock, which means a phone is tied to one network and refuses other lines. Phones bought on an operator contract are the usual case, and the operator can unlock them.
Your list before you leave India
At home, a few days before the flight
✓ Check your phone model on the supported device list.
✓ Buy your plan online and open the QR code email on a second screen.
✓ Install the eSIM on wifi, either at home or at the Terminal 3 or Terminal 2 gate wifi.
✓ Download the offline Bali map in Google Maps.
✓ Screenshot your visa confirmation, levy QR, customs form and hotel address.
On landing, turn off airplane mode, then switch on the eSIM line and set mobile data to use it. Turn on data roaming for that line only, which is how travel eSIMs connect to local networks.
The short version
Match the plan to the person: 5 GB for a couple's week, a shared 15 to 20 GB for a family, 20 GB or more for a month of work. Install at home, switch on at Denpasar, and keep an offline map for the hills.
