Indonesia's mobile network is extensive but variable across its 17,000+ islands. Telkomsel operates the largest network, covering more than 95% of populated areas with 4G/LTE and deploying 5G in Java's major cities. Bali has excellent coverage across all tourist areas including Seminyak, Canggu, Ubud, and Uluwatu cliffs. Lombok and the Gili Islands have solid 4G in Kuta and Senggigi — Gili Trawangan has adequate LTE at beach resorts. Java (Jakarta, Bandung, Yogyakarta, Surabaya) is fully covered. Major Sumatra cities have good 4G; rural Sumatra thins to 3G. Komodo National Park has 4G at Labuan Bajo port. Borneo (Kalimantan) has coverage in cities; remote rainforest areas may be offline.
Plan size
How much data do you need?
Pick your travel style and trip length — we'll suggest the right Indonesia plan, no guessing.
Yes. Bali has excellent 4G coverage in all tourist areas — Seminyak, Canggu, Kuta, Ubud, and the Uluwatu cliffside temples are all well-connected.
How is coverage on the Gili Islands?
4G is available on Gili Trawangan at beach resorts and in town. Gili Meno and Gili Air have more variable coverage. Open-water ferry crossings may have brief gaps.
Can I use this in Jakarta?
Yes. Jakarta has fast 4G/LTE with speeds up to 100 Mbps in the CBD. 5G is deploying in Sudirman, Thamrin, and other central districts.
Is this cheaper than buying a local SIM card in Bali?
Yes, comparable or cheaper — and you skip the hassle of finding a SIM shop, showing your passport, and waiting for registration.
Does this work in Komodo National Park?
Yes at Labuan Bajo port and on the main Komodo Island pier. Open water and remote islands within the park may have no signal.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical card, you scan a QR code and your plan installs instantly — no SIM tray needed.
Is my phone eSIM-compatible?
iPhone XS (2018) and newer, most Android flagships from 2020+, and all Samsung Galaxy S21+ devices support eSIM. Check our compatibility page for the full device list.
How do I install the eSIM?
After purchase, we email a QR code. On iPhone: Settings → Cellular → Add eSIM → Scan QR Code. On Android: Settings → Network & Internet → SIMs → Add eSIM. The whole process takes under 60 seconds.
Can I keep my regular SIM while using this eSIM?
Yes. Most phones support dual SIM (physical + eSIM). Keep your home number for calls and SMS — use Flysimio for data abroad. You control which SIM handles what in your phone Settings.
Does the eSIM include a hotspot (tethering)?
Yes, all Flysimio plans include mobile hotspot at no extra charge. Share your data connection with laptops, tablets, or other devices freely.
What happens when my data runs out?
You can top up data from your account dashboard at any time. Top-ups are applied instantly — no need to buy a new eSIM or wait.
Can I get a refund?
Yes. We offer a full refund within 7 days of purchase. Contact contact@flysimio.com with your order number.
How long is the eSIM valid for?
You have 6 months from your purchase date to activate the eSIM. Once activated, the plan validity period (e.g., 7 days, 30 days) begins counting down.
Will the eSIM work at the airport when I land?
Yes — as long as you installed the eSIM before your flight, it activates automatically when your phone connects to a local network on landing. No Wi-Fi required for activation.
What if the QR code doesn't scan?
If the QR code won't scan, you can enter the activation code manually — we include both in the email. You can also contact our 24/7 support team and we'll resend or manually provision your eSIM.
eSIM in Indonesia
The complete guide.
Best eSIM for travel to Bali & Indonesia
The best Indonesia eSIM — whether you're headed to Bali or beyond — combines strong coverage, honest pricing, and instant setup. Flysimio runs on Telkomsel, Indosat, and Tri, with Telkomsel operating the country's largest network across Bali, Jakarta, Lombok, and the Gili Islands. Plans are prepaid with no contract and no roaming surprises, so the price you see is what you pay. Your QR code arrives by email seconds after checkout and installs in under a minute, every plan includes free mobile hotspot, and there's a 7-day money-back guarantee. Land at Bali's Ngurah Rai or Jakarta already connected — no SIM kiosk, no passport registration.
How to set up a Bali / Indonesia eSIM (step by step)
Getting online in Indonesia takes about two minutes. First, confirm your phone supports eSIM — iPhone XS (2018) and newer and most Android flagships from 2020 qualify. Choose your Indonesia plan on Flysimio and pay with card, Apple Pay, or Google Pay; your QR code arrives by email within seconds. On Wi-Fi before you fly, open Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android) and scan it — a manual code is included too. Unlike a local SIM, there's no passport registration. Keep your home line as default until arrival; when you land at Ngurah Rai in Bali, Jakarta, or Surabaya, your Flysimio line connects automatically.
How much data do you need in Bali & Indonesia?
Most travellers over-buy. For maps, messaging, and email, roughly 300 MB a day is plenty, so a 3–5 GB plan covers a week in Bali comfortably. Add social media, photos, and reels and you'll want about 700 MB a day — a 10 GB plan suits a two-week trip across Bali, Lombok, and the Gilis. Heavy streamers, video callers, and anyone tethering a laptop for remote work should plan for 1.5 GB or more per day or choose an unlimited daily plan. Not sure? The calculator above matches your travel style and trip length to a size, and you can top up mid-trip if you run low in Ubud.
Using an Indonesia eSIM on iPhone and Android
Flysimio runs as a second line beside your usual SIM, so you keep your home number for calls and texts while your Indonesian data flows over the eSIM — standard dual-SIM behaviour on iPhone XS and later and most Android phones from 2018. After installing, set the Flysimio eSIM as your cellular-data line and turn on Data Roaming for that line only; it simply lets the eSIM connect to Indonesian networks, with no roaming fees. Keep your home SIM on for messages and calls, or switch it off to avoid your own carrier's charges. If you're unsure about your model, the compatibility page confirms it before you buy.
Hotspot, calls, and texts on an Indonesia data eSIM
Every Flysimio Indonesia plan includes mobile hotspot at no extra cost and without throttling — popular with the digital nomads working from Canggu and Ubud, since you can tether a laptop and use your full allowance freely. As a data-only eSIM it has no Indonesian phone number, but that rarely matters: WhatsApp, Instagram, FaceTime, and Google Meet all work normally over data, and your home number stays reachable on your primary SIM. You stay connected across the islands without the per-minute charges of traditional roaming.
Short Bali trips vs. long stays
For a quick Bali getaway, a small 1–5 GB plan on a 7-day validity is the most economical choice. For a two-week island-hop across Bali, Lombok, and the Gilis — or a longer nomad stay — a 10–20 GB plan or an unlimited daily option lets you navigate, stream, and work without watching a meter. Because Flysimio gives you six months to activate, you can buy before you leave and the validity only starts when your eSIM first connects in Indonesia. No contract, nothing to cancel — the plan stops when it's done, and you can top up or rebuy for your next trip.
