Best eSIM for Indonesia

When you should not buy from us

No eSIM suits every trip. These are the cases where something other than our Indonesia plan is the better buy.

• You are staying in one Bali villa with fibre Wi-Fi and barely leaving it.
• You are in Indonesia for months, where a local SIM is cheap and easy to buy.

What to compare before you buy

The cheapest Indonesia eSIM is rarely the best one. These are the things that decide whether a plan actually works for your trip.

• Price per gigabyte, not the headline price: a $5 plan with 1 GB costs more per gigabyte than a $13 plan with 5 GB.
• Whether hotspot and tethering are allowed. Many cheap plans block them, which matters the moment you open a laptop.
• What happens when the data runs out: can you top up the same eSIM, or must you buy and install a new one?
• What 'unlimited' means on that plan: almost always a daily allowance at full speed, then a much slower connection.
• Whether validity starts when you buy, when you install or when you first connect. Each of our plan pages says which.
• Whether there is a refund if the eSIM will not work on your phone, and whether a human answers when something goes wrong.

What actually matters in Indonesia

• Telkomsel reaches noticeably further than the other networks outside Java and Bali. On Flores, Sumba or the smaller islands that is the difference between a signal and none.
• Gojek and Grab are how you move around and eat in the cities, and both need a connection to work at all.
• Boat crossings to Nusa Penida, the Gilis and Komodo lose signal, and schedules change, so screenshot your booking rather than trusting you can reload it.
• Bali traffic means you spend longer navigating than the distances suggest, and maps running for an hour use real data.

How much data do you need for Indonesia?

300-500 MB a day. 5 GB for ten days in Bali, 10 GB if you are island-hopping and posting video.
