Cheapest eSIM options for trips to Indonesia

Thinking of heading to Bali or beyond and want to stay connected without spending a fortune? You’re in the right place. In this guide, I’ll break down the cheapest eSIM options for Indonesia in 2025 – from low-cost 20GB plans to unlimited data deals, plus how to choose the right one for your trip length and usage. Full disclosure: I don’t bother comparing any of those tiny data plans– you’ll almost always end up topping up and spending more (trust me, I can see the data). Want a deeper dive?

What to Look for in a Budget eSIM for Indonesia

When choosing a low-cost eSIM for Bali or broader Indonesia, price is only part of the picture. You’ve got to weigh it up against how much data you actually need, how long you’re travelling for, and what sort of experience you want. No one wants to run out of data halfway through their volcano hike or spend hours trying to fix an expired eSIM in the middle of nowhere. Here’s what I usually recommend keeping in mind when picking the best budget-friendly eSIM option.

Picking the Right Data Limit for Short Trips

For shorter holidays - say 5 to 14 days - you’d be surprised how little data most people actually use. Unless you’re glued to Instagram Reels 24/7 or uploading daily travel vlogs, 10GB is usually plenty. That gives you enough to navigate, message, browse, and post the occasional beach pic without worrying. Though with that said 20GB is only a very small price jump, at least with the ZenSim plans. You can however always top up later if you need more with any decent provider.

Picking the Right Data Limit for Longer Trips

If you’re going to be exploring Indonesia for a few weeks or more, 20GB is where things get more comfortable. It gives you enough headroom for things like booking transport, researching spots, streaming music, or hot spotting to your tablet or laptop. From my own experience and customer feedback, 20GB covers an average data without breaking the budget. You can also always opt for unlimited plans which come at a premium but really avoid the need to worry about usage.

Validity Periods – What to Watch For

One thing that catches a lot of travellers out is overthinking the number of days they actually need. At ZenSim, we offer 10-day and 30-day options, and to be honest, the price difference between them is usually only $1 or $2. So even if you're only in Indonesia for a 12-day trip, there's no need to stress about "wasting" a few days on the longer plan. In most cases, it’s more important to compare the price rather than just the duration.

Some providers out there do offer shorter-term plans - like 7 or 15 days - but once you break it down, the cost per day or per gigabyte often ends up being worse value. And if you're staying more than 30 days, no stress. With ZenSim, you can top up your plan with as many extra days as you need directly onto the same eSIM. Super easy, and you don’t need to reinstall anything or switch plans mid-trip.

Price Comparison – Top eSIM Providers for Indonesia

With so many providers offering “cheap” eSIMs for Indonesia, it can be tricky to figure out what’s actually good value. Some plans give you more data, others run longer, and some sneak in speed caps or unclear limits. Here's a breakdown of the most popular options right now, comparing price, data, and how long each plan lasts.

ZenSim

• ZenSim 20GB for A$37 ($23 USD) – 30 days
• Unlimited (3GB/day at full speed, then slowed) for A$79 ($48 USD) – 30 days

Jetpac

• Jetpac offers 20GB for A$55 ($35 USD) – 30 days
• Unlimited plan only available for 10 days
• Well-known brand, solid reviews, but fewer long-term options

Ubigi

• Ubigi provide 25GB for A$45 ($28 USD) – 30 days
• Unlimited (capped at 60GB total) for A$106 ($66 USD) – 30 days
• Extra data is a bonus, but the speed cap on unlimited is worth noting

Holafly

• Holafly only do unlimited which is A$117 ($74.90 USD) – 30 days
• No public daily cap listed, which makes it a bit of a mystery
• Great for convenience, not so great if you want transparency

If you're on a tight budget, ZenSim’s 20GB plan is the cheapest option at $23 USD. Ubigi gives you a bit more data for a few dollars extra, while Nomad stretches the plan to 45 days if you're staying longer. Jetpac suits shorter trips, and Holafly is one of the pricier options, especially without clear usage limits. Just make sure to weigh the cost against what you actually need for your trip.
