Do I need an eSIM for Indonesia?

You don't need one, but it's usually the fastest way for a visitor to get mobile data, especially in Bali where tourist SIM counters can have long queues.

Which network is best in Bali and other islands?

Telkomsel generally has the widest coverage across Indonesia's many islands; Indosat and XL are also strong in cities and Bali.

Is 5 GB enough for two weeks in Indonesia?

For normal use (maps, messaging, some social media), yes; heavy streaming will use it up faster.

Can I keep my home number active alongside the eSIM?

Yes, the eSIM runs as a second line for data while your physical SIM stays active for calls and texts.

What happens when I run out of data?

On any of these fixed-data ONE eSIM plans you can simply buy another plan or a top-up to keep going.

A week of unlimited data in Indonesia

7 days of unlimited data in Indonesia: ONE eSIM's daily plan bought for 7 days against 7-day unlimited plans, with what each gives a day. USD, checked 27 October 2026.
Provider	7 days	What you get
ONE eSIM	$15.96	1 GB a day at full speed, then 1 Mbps until the next day (7 × $2.28)
Airalo	$27.00	3 GB a day at full speed, then 1 Mbps (fair use)
Holafly	$27.50	No daily cap; fair use may slow very heavy use
Saily	$26.99	5 GB a day at full speed, then up to 1 Mbps
Nomad	–	No 7-day unlimited plan

For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $15.96. The cheapest of the others is Saily at $26.99, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.

How to set up your Indonesia eSIM

Check your phone supports eSIM (most iPhones since the XS and Android flagships since 2019 do).

Turn on the new eSIM line and enable data roaming once you land in Indonesia, then switch off your home SIM's data to avoid charges.
