Bali is one of Southeast Asia's most connected islands, with excellent 4G coverage from Telkomsel, Indosat, and XL Axiata across every major tourist area. But international roaming on your home carrier can cost $10–15/day — or more.
A travel eSIM replaces that daily roaming fee with a fixed upfront cost. For a 7-day Bali trip, you'll pay $4–17 total instead of $70–105 in roaming charges. Here are our top picks.
Our Top 3 eSIM Picks for Bali
Airalo
Airalo's Indonesia local plans are consistently the cheapest per-GB option. Plans start at $4 for 1 GB / 7 days and scale up to $14 for 20 GB / 30 days. Coverage routes through Telkomsel or Indosat, depending on the plan. The app is polished and top-ups are easy.
Best for: Budget-conscious travelers, short trips, and anyone who wants reliable coverage without paying for unlimited data.

Holafly's unlimited Indonesia plan starts at $17 for 5 days with no data cap. Routes through Telkomsel for wide coverage across Bali. The higher price buys peace of mind — no worrying about data limits while sharing photos, streaming, or video calling.
Best for: Heavy data users, content creators, and travelers who don't want to monitor usage.
View Holafly Indonesia Plans→Saily
Saily (by the makers of NordVPN) offers a clean, beginner-friendly app and competitive pricing. Plans start at $4 for 1 GB / 7 days. The setup process is the simplest we've tested — three taps and you're connected.
Best for: First-time eSIM users who want the smoothest setup experience.

Here's how the major eSIM providers stack up for Indonesia and Bali coverage:
Which plan should you choose?
For most travelers on a 7–10 day Bali trip, a 3–5 GB plan from Airalo or Saily gives you enough data for maps, messaging, Grab rides, and social media at $5–8. Heavy users or content creators should grab Holafly's unlimited plan.
Coverage & Network in Bali
Bali has excellent mobile infrastructure. Here's what to expect across the island:
Major Tourist Areas
Kuta, Seminyak, Canggu, Ubud, and Uluwatu all have strong 4G coverage from every carrier. Speeds typically range from 15–40 Mbps — fast enough for video calls, streaming, and uploading photos.
Nusa Islands
Nusa Penida, Nusa Lembongan, and Nusa Ceningan have usable 4G from Telkomsel and Indosat. Coverage can be spotty in more remote areas and along cliff roads. Download offline maps before heading over.
Gili Islands
The Gili Islands (Gili Trawangan, Gili Air, Gili Meno) have limited coverage. Telkomsel provides the most reliable signal, followed by XL Axiata on Gili T. Expect slower speeds than mainland Bali, especially during peak season.
5G Status
5G is available in parts of Denpasar on Telkomsel and Indosat networks, but it's not widespread across Bali yet. Most travel eSIM plans connect on 4G/LTE, which is more than sufficient for all travel needs.
Bottom line:If you pick an eSIM that routes through Telkomsel, you'll have the most reliable coverage across Bali — including the Nusa and Gili Islands.
How to Set Up Your eSIM for Bali
Setting up a travel eSIM takes about 5 minutes. Do this before you leave home:
Buy your plan
Choose a provider and Indonesia plan through their app or website. You'll receive a QR code or direct install link.
Install the eSIM profile
On iPhone: Settings → Cellular → Add eSIM. On Android: Settings → Network → SIMs → Add eSIM. Scan the QR code over WiFi.
Label it
Name the new line "Bali Data" or "Travel" so you can easily identify it. Keep your primary line active for iMessage and calls.
Activate on arrival
When you land at Ngurah Rai airport, turn off airplane mode. Your eSIM connects to the local network automatically. Most plans activate within 1–2 minutes.

Staying Connected in Bali: Practical Tips
Grab & Gojek Need Data
Bali's ride-hailing apps are essential — Gojek especially is used for rides, food delivery, and even payments. Both require an active data connection. Having your eSIM ready means you can book a ride straight from Ngurah Rai airport instead of negotiating with taxi drivers.
Download Offline Maps
Download the Bali region in Google Maps or Maps.me before your trip. While 4G coverage is excellent in tourist areas, you'll appreciate offline maps for rice terrace walks in Tegallalang, waterfall hikes, and areas around Mount Batur where signal can be patchy.
WiFi Is Widely Available
Most hotels, cafes, and co-working spaces in Bali offer free WiFi. Canggu and Ubud are especially well-equipped for remote workers. Use your eSIM for on-the-go navigation and apps, and switch to WiFi when available to conserve data.
Keep Your Home Number Active
With dual SIM, your eSIM handles data while your home SIM stays active for iMessage, texts, and calls over WiFi. Turn off data roaming on your home SIM to avoid surprise charges.
Frequently Asked Questions
Should I buy my Bali eSIM before or after I land?
Buy and install before you fly. Most eSIM providers let you install the profile over WiFi at home, then it activates automatically when your phone connects to a local network in Bali. This means you have data the moment you clear customs — essential for booking a Grab from the airport.
Does 5G work in Bali?
5G is available in parts of Denpasar and a few urban areas, but coverage is not island-wide. Telkomsel and Indosat are rolling out 5G gradually. For most of Bali — Ubud, Seminyak, Canggu, Uluwatu — you'll be on 4G/LTE, which delivers 10–40 Mbps and is more than enough for navigation, video calls, and streaming.
Will my eSIM work on the Gili Islands?
Coverage on the Gili Islands (Gili Trawangan, Gili Air, Gili Meno) is limited compared to mainland Bali. Telkomsel provides the most reliable signal. Expect slower speeds, especially during peak tourist season. Download offline maps before heading to the Gilis.
Can I use Grab and Gojek with an eSIM in Bali?
Yes — both Grab and Gojek work with data-only eSIMs. Gojek is particularly dominant in Indonesia and offers rides, food delivery, and payments. Having reliable data makes getting around Bali much easier and safer than negotiating with taxi drivers.
How much data do I need for a week in Bali?
For a typical 7-day vacation — maps, messaging, social media, Grab rides, and light browsing — 3–5 GB is plenty. If you plan to video call frequently or share lots of photos and reels, go for 10 GB or an unlimited plan from Holafly.
Which carrier has the best coverage in Bali?
Telkomsel has the widest and most reliable coverage across Bali, including more remote areas like Nusa Penida and the Gili Islands. Indosat Ooredoo Hutchison is the second-best option with strong coverage in tourist areas. When choosing an eSIM, check which local carrier it routes through.
Is an Indonesia eSIM the same as a Bali eSIM?
Yes — there's no Bali-specific eSIM. All eSIM plans for Indonesia cover the entire country, including Bali, Java, Lombok, and other islands. If you're island-hopping beyond Bali, the same plan works everywhere.
Can I top up my eSIM if I run out of data in Bali?
Most providers — including Airalo, Saily, and Alosim — allow you to buy additional data through their app. Holafly's unlimited plans don't require top-ups. You can also purchase a second eSIM if your provider doesn't offer top-ups.
