Airalo Bali eSIM: Pros, Cons & Alternative

Airalo Bali eSIM review: the quick version

Airalo is one of the biggest names in travel eSIMs, and its Indonesia eSIM is a go-to for plenty of travellers heading to Bali. It's a Singapore-based brand selling data-only eSIMs for over 200 destinations, with a slick app and a wide spread of plan sizes. For a Bali trip it does the job, and for a lot of people that's enough.

Where it gets more interesting is when you line it up against the alternatives. On the plans most Bali travellers actually buy, 20GB and unlimited for 30 days, ZenSim comes in at A$45 ($29 USD) and A$99 ($69 USD), against A$51 and A$100 for Airalo. Both have the same 3GB daily cap on unlimited and both allow unlimited hotspotting. The bigger gaps show up in customer reviews, how you get help when something goes wrong, and plan options like a 40GB middle ground. Here's the full breakdown, the good bits included.

Does Airalo work in Bali?

Yes, Airalo works in Bali. Its Indonesia eSIM covers Bali along with the rest of the country, so Seminyak, Canggu, Ubud, Uluwatu and day trips to Nusa Penida, the Gilis and Lombok are all on the same plan. Like every travel eSIM, it needs a phone that's eSIM-compatible and carrier unlocked, and it's data-only, so there's no Indonesian phone number for traditional calls or SMS. WhatsApp, Grab and Google Maps all work fine on data.

Speed is where travel eSIMs differ more than most people expect. Two eSIMs can use the same local networks and still feel different on the ground, because of how each provider routes its traffic. In our own testing around Bali, ZenSim delivered better real-world speeds than Airalo, particularly in busy spots like Canggu and Seminyak at peak times. Your mileage will vary with location and time of day, but if you're planning to upload, stream or hotspot a laptop for work, it's worth knowing.

Is Airalo good for Bali? Pros and cons

Airalo has earned its popularity, so it's only fair to start with what it does well:

• A well-known brand with a polished app and a simple checkout
• A wide range of Indonesia plan sizes, including small packs for short trips
• Unlimited hotspotting, with the same 3GB daily cap on unlimited as most providers
• Coverage across all of Indonesia, not just Bali

And where it falls short for a lot of Bali travellers:

• A 3.9/5 rating on Trustpilot, well behind ZenSim's 4.9/5 on ProductReview.com.au
• Support runs through an in-app ticketing system rather than chat with a real person
• Slower real-world speeds than ZenSim in our own testing around Bali
• No Australian-based support team, which matters when you're in a time zone crunch

If you just want a small data pack for a few days and you're comfortable sorting out any issues through tickets, Airalo is a fair pick. If you want a 20GB, 40GB or unlimited plan with fast human support, ZenSim is built for exactly that.

Airalo vs ZenSim for Bali

Here's how the two stack up feature by feature on their Indonesia eSIMs, using regular prices rather than flash sales (checked September 2026).

On price, ZenSim is about A$6 cheaper on 20GB, and the unlimited plans are close to line ball. The 40GB plan is the sneaky winner for longer trips and families, sitting between 20GB and unlimited without paying unlimited money. The real split is everything around the data. ZenSim's 4.9/5 rating comes from more than 400 reviews, and when something goes sideways you can message the team on WhatsApp and get an answer from a human, not a ticket number.

How much is an Airalo eSIM for Bali?

Airalo's Indonesia eSIM comes in a range of data packs, from small top-up sized plans through to 20GB and unlimited. For a 30 day trip, its 20GB plan is A$51 and unlimited is A$100, based on our September 2026 price check. Prices can shift, so it's worth checking Airalo's app on the day you buy.

On ZenSim, the same 20GB plan is A$45 ($29 USD) and unlimited is A$99 ($69 USD), and you can see every plan size and price at the top of this page. Not sure how much data you need? A 15 day plan covers most week-long and two-week trips, 10GB suits average use, and unlimited makes sense if you're hotspotting a laptop or posting every day.

Airalo reviews: what to look for

Airalo sits at 3.9/5 on Trustpilot, which is a solid score for a brand its size but a fair way behind ZenSim's 4.9/5 from 442 reviews on ProductReview.com.au. When you're reading eSIM reviews for Bali, it pays to look past the star rating and into what people actually say about two things: speeds in busy areas and how quickly problems get fixed.

Speed complaints usually come from crowded spots at peak times, which is exactly where you'll be if you're in Canggu or Seminyak at sunset. Support complaints tend to come from travellers who hit an install or connection issue on arrival and had to wait on a ticket while standing in the arrivals hall. ZenSim's reviews consistently call out fast, friendly help on WhatsApp, which is the difference between a five minute fix and a frustrating first night.

Buying a Bali eSIM from Australia: Airalo or ZenSim?

Most Aussies sort their Bali data before they leave home, and both brands let you buy online and install on your home WiFi a few days before you fly. The eSIM sits ready on your phone and switches on once you land in Denpasar, so you're connected before you've even cleared immigration.

The differences show up after you hit buy. ZenSim is an Australian company, prices are in Aussie dollars with no conversion surprises, and support works on Aussie hours over WhatsApp and Messenger. Airalo is a global brand with support handled through its in-app ticketing system. If everything works first time, you might never notice. If it doesn't, having a local team a message away makes sorting it out a bloody breeze. And if your phone turns out not to be compatible, ZenSim's refund policy has you covered.

Unlimited data and hotspotting: Airalo vs ZenSim

On unlimited plans the two are more alike than different. Both include 3GB of high-speed data per day, which covers Maps, Grab, WhatsApp and a healthy amount of scrolling. Go over it and speeds drop until the next day, which on ZenSim means 1Mbps until midnight, still enough for messaging and booking a ride home.

Both also allow unlimited hotspotting, so you can share data with a laptop or the kids' tablets. Keep in mind the 3GB daily allowance is shared across every device on your hotspot. That's where ZenSim's 40GB plan earns its keep. For a couple sharing data or a family trip, 40GB for 30 days gives you a big bucket to dip into without a daily cap, and it's something Airalo doesn't offer in Indonesia.

Switching from Airalo to ZenSim

Already have an Airalo eSIM on your phone? No drama. Most eSIM-compatible phones can store several eSIMs at once, so you can install ZenSim alongside it and simply switch which one handles mobile data in your settings. There's no need to delete your Airalo eSIM unless you want the space back.

Install ZenSim at home before you fly, set it as your data line when you land, and keep your Aussie SIM switched on for texts like bank codes with roaming turned off. If you run low during the trip, you can top up in the ZenSim app without reinstalling anything, and our help guides walk you through it. Not sure your phone supports eSIM at all?
