eSIM Neden Endonezya için Fransa'dan Alınmalı?
Look, I've spent enough Thanksgiving holidays figuring out local SIMs in various airports that I've learned my lesson. Trying to find a reliable SIM card vendor after a 16-hour flight, especially when you're jet-lagged and just want to get to your Airbnb in Canggu, is a special kind of hell. Doing it from France means you're not trying to debug connectivity issues in a foreign language with a rapidly dying phone battery. You handle it at home, where you have stable Wi-Fi and time to deal with any hiccups. Your EE plan, while great for catching up on Netflix back in the UK, will hit you with brutal day-pass charges in Indonesia. A typical day pass from a home carrier like EE can easily run you £7-10 a day. For a month-long stay, that's £210-£300, which is roughly what I pay for a decent room in a co-living space in Ubud (think about 4.5 million IDR, or around £230 for a month's rent). Why spend that on data when you don't have to?
Setting up an eSIM beforehand also means you can immediately use ride-hailing apps like Gojek or Grab, which are absolutely essential for getting around. Some local apps, particularly banking apps if you're planning a longer stay, might even require a local number for verification, though for most tourists, a data-only eSIM is sufficient. The best part? You can compare options from France, pick the plan that suits your data needs, and even load it onto your device while sipping coffee at your favourite Parisian café, rather than sweating it out at Denpasar airport.
Endonezya eSIM Nasıl Alınır: Fransa'dan Adım Adım Satın Alma
Buying an eSIM for Indonesia from France is straightforward. The key is to choose a reputable provider like Cellesim. Here's how I typically do it, usually a week or two before I fly out from Heathrow.
- Choose Your Provider and Plan
Head to the Cellesim website or app. You're looking for an Indonesia eSIM. Pay close attention to the data allowance, validity period, and whether it's data-only or includes a local number (most tourist eSIMs are data-only, which is fine for WhatsApp and online calls). For a typical two-week trip, 10-20GB should be plenty if you're not constantly streaming. If you're staying for a month, especially if you plan to use it for tethering in a co-working space like Outpost in Canggu, I'd bump that up to 30GB or more. - Purchase Your eSIM
Once you've selected your plan, proceed to checkout. You'll enter your payment details. The process is usually quick and secure. - Receive Your eSIM QR Code or Activation Details
After your purchase is complete, you'll receive an email containing a QR code or manual activation details. This is the crucial part. Do not activate this until you are ready to install it on your device. Keep this email safe. - Download and Store the QR Code
I always recommend taking a screenshot of the QR code and saving it to your device's photo gallery, or even printing it out. If you're installing the eSIM on the same device you're viewing the email on, you'll need another screen to scan the QR code. My go-to is usually scanning from my laptop screen or a friend's phone.
eSIM Kurulumu: Varış Öncesi Hazırlıklar
This is where you actually get the eSIM onto your phone. You can do this at home, in France, before you even leave for the airport. Just make sure you have Wi-Fi.
- Open Your Phone's Settings
For iPhones, go to Settings > Cellular > Add eSIM. For Android phones, it's usually Settings > Network & Internet > SIMs > Add more or something similar, depending on your manufacturer (Samsung, Google Pixel, etc.). - Scan the QR Code
When prompted, choose the option to 'Use QR Code' or 'Scan QR Code'. Point your phone's camera at the QR code you received in your email (or printed out). Your phone should recognise it almost instantly. If you need to enter details manually, you'll find them in the same email. - Label Your eSIM
Once scanned, your phone will ask you to label the new eSIM. Call it something clear like 'Indonesia Data' or 'Cellesim Indo'. This helps keep things organised, especially if you have multiple eSIMs. I usually keep my primary EE SIM active for calls and texts (for things like bank verifications, though for true long-term travel, you'll eventually need a local number for some services like Brazilian banking apps or India's Aadhaar). - Choose Your Default Line (Optional)
Your phone might then ask which line you want to use for data, calls, and texts. For now, leave your primary EE SIM as the default for calls and texts. Crucially, do not switch your data to the Indonesia eSIM yet. We'll do that once you land.

This is the moment of truth. You've landed, cleared immigration, and you're ready to get online. The beauty of the eSIM is that you don't need physical contact with a vendor.
- Disable Your Primary SIM's Roaming
Before you switch, go to your phone's settings and find your primary EE SIM. Make sure 'Data Roaming' is turned OFF for this line. This is a critical step to avoid any accidental charges. - Switch Data to Your Indonesia eSIM
Now, go back to your Cellular/Network settings. Under 'Cellular Data' or 'Mobile Data', select your 'Indonesia Data' eSIM as the preferred line for data. - Enable Data Roaming for eSIM (If Required)
Some eSIMs, depending on the provider, might require you to enable data roaming for the eSIM itself. Check the instructions provided by Cellesim for your specific plan. For most travel eSIMs, this is usually needed as they often roam on local networks. - Restart Your Phone (Optional but Recommended)
A quick restart can often help your phone register with the local network more smoothly. I've found this helps particularly in less urban areas, like when I was trying to get signal in a small warung in Kerobokan. - Confirm Connectivity
You should now see network bars and possibly an 'LTE' or '5G' indicator. Try opening a browser or an app like WhatsApp to confirm you have data. If all goes well, you're connected. You can now call that Gojek without having to hunt for Wi-Fi.
Sık Karşılaşılan eSIM Sorunları ve Çözümleri
Even with careful planning, things can sometimes go sideways. Here are the top three issues I've seen and how to tackle them.
eSIM Not Activating or Connecting
This is probably the most common headache. You've followed all the steps, but no data.
- Check Data Roaming Settings: Double-check that data roaming is enabled for your Indonesia eSIM and disabled for your primary EE SIM. This is the culprit 90% of the time.
- APN Settings: Sometimes, the Access Point Name (APN) settings aren't automatically configured. Your eSIM provider (Cellesim, in this case) will provide the correct APN settings in your confirmation email or on their support pages. Go to your phone's cellular settings, find the eSIM, and look for 'APN' or 'Access Point Names'. Enter the details manually.
- Network Selection: Try manually selecting a network. In your phone's settings, under the eSIM details, look for 'Network Selection' and turn off 'Automatic'. You should see a list of local Indonesian carriers (e.g., Telkomsel, XL Axiata). Try connecting to each one until you find one that works. Telkomsel is generally the most reliable for coverage across the archipelago, from Bali to Flores.

Slow or Intermittent Data
You have connection, but it's crawling, or keeps dropping out. This can be frustrating, especially if you're trying to work remotely from a café like Revolver Espresso in Seminyak.
- Check Coverage: Are you in a particularly remote area? Even in Indonesia, there are still spots with patchy coverage. Move to a more open area or higher ground if possible.
- Restart Phone: A simple restart can often clear up minor network glitches.
- Network Congestion: Sometimes, especially in popular tourist areas or during peak hours, networks can get congested. There's not much you can do here besides moving to a different location or trying again later.
eSIM Disappears or Becomes Unresponsive
This is rare, but it happens. Your eSIM profile might seem to vanish or become greyed out.
- Reinstall the eSIM: If you saved your QR code or activation details, try removing the eSIM profile from your phone (make sure you delete the correct one!) and then reinstalling it using the original QR code. This usually resolves the issue.
- Contact Support: If all else fails, reach out to Cellesim's customer support. They can often diagnose problems remotely or issue a new eSIM profile if yours is corrupted. For any general questions about eSIMs and troubleshooting, their FAQ page is usually a good first stop.
Frequently Asked Questions
Can I use my existing French phone number with an Indonesian eSIM?
Yes, you can. Your French SIM (like EE) will remain active for calls and texts while you use the Indonesian eSIM for data. Your phone will usually allow you to specify which line handles calls, texts, and data independently.
Is it better to buy an eSIM or a physical SIM card in Indonesia?
For short-term travel, an eSIM purchased in advance from France is almost always better. It saves you time and hassle at the airport, and you're connected instantly. For longer stays, especially if you need a local number for banking or a visa (like the B211A digital nomad visa which might require a local number for certain administrative processes), a physical SIM might be necessary, but you can still use an eSIM for your initial data.
How much data do I need for a two-week trip to Indonesia?
For a typical two-week tourist trip with moderate usage (maps, social media, light browsing, WhatsApp calls), 10-20GB should be sufficient. If you plan to heavily stream videos, use it for extensive tethering, or work remotely, consider a 30GB+ plan. My monthly usage for working from places like Hubud in Ubud usually hovers around 50GB.
Can I top up my Indonesian eSIM if I run out of data?
Most travel eSIM providers, including Cellesim, offer top-up options through their app or website. You can usually purchase additional data packages if your initial allowance runs low, often with similar validity periods.
What should I do if my eSIM doesn't work upon arrival in Indonesia?
First, restart your phone. Then, double-check that data roaming is enabled for your Indonesian eSIM and disabled for your primary SIM. Verify APN settings against the provider's instructions. If problems persist, try manually selecting a network operator in your phone's settings. If none of these work, contact your eSIM provider's support for immediate assistance.
