Introduction
Are you planning a trip to Indonesia? Great choice. Between the volcanic landscapes, tropical beaches, and over 17,000 islands, you’re in for a treat.
But there’s one point we tend to underestimate… it’s the internet connection. And yet, whether it’s to keep in touch, use GPS, or share your moments, it quickly becomes essential.
We tell you this because we’ve been there. We took a long trip to Indonesia, and clearly, we didn’t anticipate as we should have. The result: hassles, bad surprises… and a few pounds that disappeared a bit too quickly.
So, the idea here is simple: to help you avoid making the same mistakes we did (because yes, we would have loved to come across this kind of article before leaving).
We will look together at the best solutions for getting internet in Indonesia, without headaches and without blowing your budget.

How to find the ideal unlimited SIM card for your trip to Indonesia?
If Indonesia is on your list, this country with breathtaking landscapes, vibrant culture and unforgettable sights, then get ready for an extraordinary journey. But before you get lost in the bustle of Jakarta or marvel at the views of Nusa Penida, one essential question arises: how to stay connected in Indonesia?
No panic, we’re here to guide you through the maze of mobile options.
Three alternatives emerge to ensure your connectivity in Indonesia:
Use your UK plan abroad thanks to roaming agreements
Buy a local SIM card to benefit from local rates
Activate an eSIM before your departure, without changing your physical card

Solution 1: Using your UK mobile plan in Indonesia
It might seem logical to think you can just use your UK mobile plan in Indonesia. After all, your operator probably offers some form of roaming… so it should be fine, right?
Well… not quite.
No, you won’t be able to casually post your latest photos on Instagram of your trip to Bali without it costing a small fortune.
Unlike European destinations where roaming is often included, Indonesia falls outside the standard roaming zones for most UK operators. That means daily passes, bolt-ons, and per-MB charges that add up fast (and we speak from experience).
As a result, this seemingly simple solution on paper is far from being the most suitable for a trip to Indonesia.
UK operator roaming in Indonesia
Here’s what each of the four major UK operators offers for Indonesia — and as you’ll see, the options are far from generous:
EE places Indonesia in Zone 4, where you get just 500 MB per day for around £7.50. That’s barely enough to check your emails, let alone share photos or use GPS.
Three UK covers Indonesia via Go Roam Around the World Extra at £8 per day, with a 12 GB monthly fair usage cap. Decent in theory, but the daily cost adds up quickly on a longer trip.
Vodafone UK puts Indonesia in Zone D at around £8 per day, with a 25 GB monthly cap. Similar pricing to Three, slightly more generous on data.
O2 offers the Travel Bolt On at £7 per day with unlimited data (throttled to 2 Mbps) across 75 destinations including Indonesia. Usable, but the speed limit makes video calls and streaming painful.

Are you wondering what you can do with 1 GB of data? Here are some concrete examples:
- Listening to music on Spotify for 1 hour every day will last you 20 days.
- Watching an HD video (1080p quality) for 30 minutes.
- Binge-watching 4K videos for 10 minutes.
- Video chatting for 4 hours on WhatsApp, or having fun on Insta and TikTok.

Advantages:
To be fair, there is one advantage: convenience. You don’t need to buy anything extra — just activate a roaming pass from your operator’s app before you land.
Three UK and O2 offer the most usable options for Indonesia, with reasonable daily rates and enough data for basic use. If you’re only going for a long weekend and don’t use much data, it can work.
But beyond 3-4 days, the daily charges start adding up to a point where other solutions become significantly cheaper.
Disadvantages:
The cost is the main issue. At £7-8 per day, a two-week trip to Indonesia would cost you £98-112 just for mobile data — that’s more than many monthly UK phone contracts.
EE is practically unusable in Indonesia with only 500 MB per day in Zone 4. And O2’s unlimited option is throttled to 2 Mbps, which makes video calls and streaming frustrating.
The bottom line: UK operator roaming in Indonesia is expensive, limited, and often confusing with zone classifications that vary between operators. There are much better alternatives, as we’ll see below.
Solution 2: Local SIM card in Indonesia
The second option is to get a local SIM card once you’re there. By choosing this route, you avoid roaming fees and enjoy local rates for mobile internet, which can make a real difference for longer stays.
In practice, you can find a card quite easily, whether at an airport, a telecom store, or in local sales points (and that’s part of the experience).
Which local mobile operator for a stay in Indonesia?
In Indonesia, the main mobile operators are Telkomsel, Indosat Ooredoo Hutchison, XL Axiata, and Smartfren. The idea is to compare the network coverage and mobile data allowance based on your route, and to check the validity period of the SIM card before you buy.
Once you’ve bought your local SIM card, simply insert it into your phone and follow the activation instructions. And just like that, you’re ready to explore Indonesia while staying connected like a local.

The main competitor. Very popular in Bali and Lombok with coverage often comparable to Telkomsel in tourist areas for a slightly lower price.
Smaller operator but very innovative with Data. The ONLY one offering a Tourist eSIM purchasable and activatable 100% online before departure (via their official website).

Advantages:
For longer stays or heavy data users, a local Indonesian SIM card is often the most cost-effective option. Local tourist plans typically give you far more data per pound than UK roaming caps allow.
You also get full local rates for calls and texts inside Indonesia, which is useful if you’re booking accommodation, calling restaurants, or arranging activities on the ground.
Disadvantages:
Language Barrier and Technical Complexities
When purchasing, setting up, or even troubleshooting, you might feel lost with technical jargon, unless the shop’s English is up to it.
Device Incompatibility
First and foremost, make sure that your smartphone or 4G modem is unlocked and compatible with local frequencies. Also, pay attention to the SIM card size, which can vary and may not fit your phone.
Risks and Downsides
- Loss of Your UK Number: By replacing your SIM, you risk temporarily losing your regular number, which can be inconvenient if you’re expecting important calls or 2FA codes.
- Frequent SIM Changes: If your travels take you on to Singapore or Malaysia, you might need to change SIM cards more than you’d like.
- Documentation requirements: Some Indonesian operators ask for ID, a local address, or a minimum subscription duration — worth checking before you go.

Solution 3: Holafly eSIM for Indonesia
For us, there is a third solution: the Holafly eSIM for Indonesia. And here, we are clearly on the simplest option if you don’t want to hassle.
No store, no paperwork, no complicated handling. You activate your eSIM, and you’re connected.
In practice, it allows you to stay connected easily everywhere in Indonesia: receive booking confirmations from your hotel in Jakarta, book a restaurant on your favorite app, or organise your visits without ever worrying about your connection (and that, while traveling, is a real comfort).
What is an eSIM?
An eSIM is simply a SIM card integrated directly into the phone. No need for a physical card, everything is done online in a few minutes.
And on top of that, you can have multiple eSIM profiles on your smartphone, which allows you to keep your UK number active while using local internet in Indonesia. So you don’t miss a call or a 2FA code from home.
Advantages:
The main advantage here is clearly peace of mind before departure. You download your eSIM calmly at home, either via the app or directly by email.
As a result: you arrive in Indonesia already ready to be connected. You can even activate your line just before boarding the plane or upon exiting the airport (and that makes all the difference when arriving in a country you don’t know).
Then, everything is much simpler: no paperwork, no store, no unpleasant surprises. You enjoy an immediate internet connection without constraints, whether in Bali, Yogyakarta, or elsewhere.
And on top of that, you keep your UK number active in parallel, while using the internet locally. In short, it’s a quick, efficient solution, and above all, hassle-free.
Disadvantages:
The main point to keep in mind is that the price can be higher than a local SIM card, especially if you stay a long time in Indonesia.
Depending on the offers, you may also have plans with limited data. So if you consume a lot of internet, you need to check carefully beforehand.
Finally, one last important point: not all smartphones are eSIM compatible. Be sure to check your device before choosing this solution.
