Global eSIMs vs. Local Indonesian Carriers
When you're trying to decide on data for your Indonesian adventure, the first fork in the road is always: do I go with a global eSIM provider that I can set up before I even leave France, or do I wait and get a local Indonesian SIM or eSIM? For families, this isn't just a matter of convenience; it's about minimising stress when you're already juggling luggage, tired kids, and unfamiliar surroundings.
Global eSIM providers like Airalo, Holafly, or Cellesim offer plans for Indonesia that can be purchased and activated from your couch in Paris. This means your phone, and crucially, your children's iPads or Nintendo Switches, can be connected the moment you land. Imagine, stepping off the plane at Denpasar, and instead of hunting for a SIM card vendor, you're already checking Grab for your ride to Ubud, while the kids immediately connect to their pre-loaded games or a downloaded Disney+ episode. That's a huge win in my book, especially after a long-haul flight.
Local Indonesian carriers, primarily Telkomsel and XL Axiata, also offer eSIMs. These usually provide more data for your money and can sometimes offer slightly better local network speeds, particularly if you're venturing off the beaten path. However, you often need to register them with your passport in person, which can be a bit of a bureaucratic dance at the airport or a local store. While Telkomsel eSIM Bali can be a solid option for individuals, the multi-device scenario for a family adds complexity.
| Feature | Global eSIM Providers (e.g., Cellesim, Airalo) | Local Indonesian Carriers (e.g., Telkomsel) |
|---|---|---|
| Purchase & Activation Location | From France, before travel | In Indonesia, often requiring in-person registration |
| Convenience for Families | High, instant connectivity on arrival | Lower, requires airport or store visit, potential queues |
| Data Volume vs. Cost | Good value, but sometimes less data per euro | Excellent value, more data per euro |
| Setup Difficulty | Easy, QR code scan from your current phone | Can be complex with registration requirements |
| Multi-Device Support | Easy to manage via a single hotspot or multiple eSIMs | Requires separate purchases or complex sharing |
My take: for family travel, particularly with younger kids, the convenience of a global eSIM provider like Cellesim simply cannot be beaten. The ability to land and immediately connect to a pre-arranged plan, without any fuss, is worth a small premium.
Data Needs for the Family: Disney+ and Beyond
Let's be real: family travel today means devices. Lots of them. My two (ages 9 and 11) have their iPads for Minecraft and Roblox, plus my eldest has a Switch for online gaming with friends back home. Then there's my phone for navigation, booking tours, and keeping up with the parents' WhatsApp group, and my husband's for emails (because someone has to work). That's at least four devices constantly vying for data.
Streaming Disney+ for two kids on a rainy afternoon in Seminyak, or allowing them to catch up on YouTube Kids during a long car ride to Candidasa, eats data faster than you can say 'Are we there yet?'. An hour of standard definition streaming can be around 0.7 GB. If both kids are streaming for two hours a day, that's almost 3 GB gone. Factor in map usage, social media, messaging, and whatever else teens do on their phones, and you're looking at a substantial data requirement.
For a two-week trip, I typically budget at least 10 GB per adult and 5-7 GB per child, minimum. This isn't just for entertainment; it's for essential things like checking hotel bookings, using Google Translate, and emergency calls. Pre-loading apps like Google Maps (offline maps are a lifesaver), language translation tools, and entertainment (movies, audiobooks) before you leave France can significantly reduce your daily data consumption, but you'll still need a robust plan.
What I look for in an eSIM is often a pooled data option or at least large individual allowances. Some global providers offer regional plans that cover multiple countries in Southeast Asia, which is fantastic if you're hopping from Bali to Singapore for a few days. Just ensure the data allowance is generous. For a family of four, aiming for a total of 50-70 GB over two weeks is a comfortable starting point, especially if you're not always relying on hotel Wi-Fi.
Coverage and Reliability: Where Your Family Will Actually Be
Indonesia is vast, and while Bali has excellent connectivity, other islands or even remote parts of Bali might be a different story. The main local players are Telkomsel and XL Axiata, with Telkomsel generally having the widest coverage, especially outside of major tourist hubs. When global eSIM providers offer plans, they usually piggyback on one of these local networks. It's crucial to know which network your chosen eSIM provider uses.
Think about your itinerary. Are you sticking to the well-trodden paths of Seminyak, Ubud, and the Gili Islands? Or are you planning to explore Nusa Penida, Lombok, or even further afield? Connectivity inside theme parks, like Waterbom Bali, is generally good, as are most major resorts and cruise ships around the archipelago, but those moments in transit between islands or on a remote beach can be patchy. Having a reliable connection means you can easily check ferry schedules or find an alternative activity when the kids are getting restless.
From my experience, Cellesim often partners with the strongest local networks, offering that peace of mind. Before purchasing, a quick check of their website or customer service can confirm which local operator they use in Indonesia. This is especially important if you're relying on data for navigation (Google Maps is essential) or for keeping track of your children using apps like Life360.
| Provider Type | Primary Network Partner (Indonesia) | Coverage Strength (Bali/Java) | Coverage Strength (Remote Areas) |
|---|---|---|---|
| Cellesim | Telkomsel or XL Axiata (check specific plan) | Excellent | Good, often best available |
| Airalo | Telkomsel or XL Axiata (check specific plan) | Excellent | Good, depends on partner |
| Holafly | Telkomsel | Excellent | Good |
| Telkomsel (Local) | Telkomsel | Excellent | Best available |
| XL Axiata (Local) | XL Axiata | Good | Moderate to Good |
Always check the specific plan details. Some eSIMs might offer excellent coverage in Jakarta but be weaker on a small island off the coast of Sumatra. The goal is consistent connectivity, not just the cheapest option.
Parental Control and Device Management with eSIMs
This is where things get interesting for me as a parent. We all know the drill: the iPad needs a data top-up, or you want to ensure the kids aren't accidentally racking up charges on premium sites. While eSIMs primarily provide data, they also influence how you manage your family's screen time and device usage abroad.
Most global eSIMs are data-only, meaning they don't come with a traditional phone number for calls and SMS. This is actually a blessing in disguise for parental controls. It means that while the kids can use WhatsApp, Messenger Kids, or FaceTime over data, they can't make traditional calls to unknown numbers or receive spam texts. You can also use your existing phone's parental control features, like Apple's Screen Time or Google's Family Link, which will work seamlessly over the eSIM data connection.
If you're tethering your kids' devices to your phone's hotspot (which is how I often manage their iPads), you have full control over when they get online and for how long. I find this invaluable for managing screen time on holiday. If their iPad needs a top-up, it needs to connect to my phone, giving me a chance to check in. If you opt for individual eSIMs for older children, remember to enable their device's built-in parental controls before you leave France.
One thing to be aware of: some services require a local phone number for two-factor authentication (OTP). This is usually for banking or specific local apps. Since most eSIMs don't provide a local number, you might encounter issues. Make sure any critical accounts that rely on OTP are set up to send codes to your primary French number (if you keep it active for SMS roaming) or an alternative method before you travel.

Cost Comparison: Getting the Best Value for Your Family
Let's talk money. Roaming charges from French networks are simply not an option for families. A single day's roaming can be €10-€15 per device, and that adds up horrifically over a two-week trip for four people. You could easily spend hundreds of euros just on data.
For families, the best value usually comes from purchasing a larger data package that can be shared via hotspot, or individual, moderately sized eSIMs for each data-consuming device (parent phones, older kids' phones/tablets).
Here's a quick comparison of typical costs for a 15-day trip to Indonesia, assuming a family of four needs around 40-50 GB total data:
| Provider Type | Data Allowance (Example) | Validity | Approx. Cost (EUR) | Notes for Families |
|---|---|---|---|---|
| Cellesim (Indonesia) | 50 GB | 30 days | €35 - €45 | Excellent value for shared data via hotspot. Reliable network. |
| Airalo (Indonesia) | 30 GB | 30 days | €28 - €38 | Good for individual devices, may need multiple purchases for family. |
| Holafly (Indonesia) | Unlimited* | 15 days | €47 - €57 | Unlimited data is appealing, but often throttled after a certain threshold. High cost. |
| Telkomsel (Local eSIM) | 50 GB | 30 days | €25 - €35 | Best price per GB, but requires in-person registration in Indonesia. |
| French Network Roaming | Varies, daily cap | Daily | €150 - €200+ (for 15 days, 1 phone) | Prohibitively expensive, avoid at all costs. |
(*Note on 'unlimited' plans: always read the fine print. Many 'unlimited' eSIMs, like those from Holafly, have fair usage policies that significantly throttle speeds after a certain amount of data is consumed, making them less ideal for multiple simultaneous streams of Disney+.)

The sweet spot for families typically involves a balance between upfront cost, data volume, and ease of use. Cellesim's larger packages often hit this sweet spot perfectly.
The Verdict: Best eSIM for Families Travelling to Indonesia from France
After countless family trips and wrestling with various connectivity solutions, my recommendation for families travelling to Indonesia from France is clear: a global eSIM provider, and specifically, I lean towards Cellesim for its balance of reliability, data options, and ease of purchase from home.
Here's why:
- Pre-travel setup: You can purchase and activate your Cellesim plan before you even leave France. This means instant connectivity on arrival, which is invaluable when you're managing children after a long flight. No scrambling at the airport for a local SIM, no language barriers, just working data from the moment you land.
- Data for multiple devices: Cellesim offers generous data packages that can easily support the needs of a family. Whether you're hot-spotting for two iPads streaming Disney+, checking Google Maps, or uploading holiday snaps, you'll have enough. (Remember, I pre-load all streaming content where possible, but a good connection is still essential for updates and new viewing.)
- Reliable network access: Cellesim typically partners with strong local networks like Telkomsel, ensuring you get the best possible coverage across Bali and other popular Indonesian destinations. This consistency is crucial for navigation, keeping in touch, and allowing you to confidently use parental control features that rely on a stable internet connection.
The only real downside to a global eSIM like Cellesim, when compared to a local Telkomsel eSIM, is that you might pay a few extra euros for the same amount of data. However, the convenience and peace of mind you gain by avoiding in-person registration and guaranteeing connectivity from the moment you arrive are, for me, well worth that small premium. When you're dealing with tired children and the logistics of international travel, anything that smooths the process is a win.
So, save yourself the hassle. Get your Indonesia eSIM from Cellesim sorted before you fly, load up those iPads with offline content, and enjoy a connected, stress-free family adventure in Indonesia.
Frequently Asked Questions
Can I use my French phone number with an Indonesian eSIM?
Yes, you can typically keep your French physical SIM card active in your phone for calls and SMS while using an Indonesian eSIM for data. Your phone will simply use the eSIM for internet access, and your primary SIM for its original number. Just be mindful of roaming charges for calls and texts on your French number.
How much data does a family of four need for two weeks in Indonesia?
For a family of four, including two children who might stream content, I recommend a minimum of 50-70 GB for a two-week trip. This accounts for navigation, social media, messaging, and moderate streaming for the kids. Pre-downloading movies and maps helps reduce this, but it's always better to have more than run out.
Will an eSIM work on my children's iPads or Nintendo Switch?
Most iPads and Nintendo Switches do not directly support eSIMs. However, you can easily use your phone with an active eSIM as a mobile hotspot. This allows your children's devices to connect to the internet through your phone's data, ensuring they stay connected for games, streaming, and educational apps.
What happens if I run out of data on my eSIM in Indonesia?
If you run out of data, most eSIM providers like Cellesim allow you to easily top up your plan directly through their app or website. This can be done quickly and conveniently from your phone, without needing to find a local store or purchase a new SIM.
Is Wi-Fi widely available in Indonesia for families?
Wi-Fi is generally available in hotels, guesthouses, restaurants, and cafes in major tourist areas like Bali. However, speeds can vary, and it may not always be reliable. Having your own eSIM data ensures consistent connectivity for navigation, communication, and keeping children entertained, especially during transit or in less developed areas.
Can I set parental controls on an eSIM data plan?
eSIMs primarily provide data, so direct parental controls are typically managed through your device's operating system (like Apple's Screen Time or Google's Family Link). If you're hot-spotting for your children's devices, you have direct control over their internet access. For individual eSIMs, set up device-specific parental controls before travel.
