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, 5–10 GB costs $11.52–19.20 total instead of $70–105 in roaming charges.
Every price in this guide was read directly off each provider's own Indonesia page in September 2026 — 14 providers in all. There's no Bali-only eSIM; an Indonesia plan covers Bali, Lombok, and the rest of the country. We ranked on price per GB and on which network each eSIM uses, not on which provider pays us more.
Our Top 3 eSIM Picks for Bali
Yesim
Yesim runs on Telkomsel, Bali's widest network, and among 30-day plans on Telkomsel it's the cheapest at 5 GB and 20 GB: 5 GB for $11.52, 10 GB for $19.20, and 20 GB for $26.40 ($1.32/GB) — the cheapest 30-day 20 GB from any provider outside the MobiMatter marketplace. Every fixed plan runs 30 days, even the 1 GB at $3, so a short trip doesn't cost you validity.
Best for: Most Bali trips, especially if you're heading to Nusa Penida or the Gilis. The honest tradeoffs: Ubigi and Nomad are slightly cheaper at exactly 10 GB ($16 and $19), and Yesim shows its prices as discounts against much higher list prices (20 GB is listed at $60), so confirm the price at checkout. Its unlimited plans are no bargain at $68.40 for 30 days.

Nomad also runs on Telkomsel and ties Ubigi for the cheapest week from a provider that names its network: 1 GB for 7 days at $4. Its 10 GB is $19, and its larger plans run 45 days instead of 30: 20 GB for $33 and 50 GB for $41 ($0.82/GB), the cheapest 50 GB from a mainstream provider.
Best for: Remote workers in Canggu or Ubud and anyone staying longer than a month. The tradeoffs: Nomad's fixed plans are 4G only (its unlimited plans are 5G), and unlimited comes in just 5- and 10-day lengths, slowing after 2 GB a day.
View Nomad Indonesia Plans→Maya
If you want unlimited data, Maya is the cheapest way to get it in Indonesia: 30 days for $49.99, against $59 from Ubigi, $69 from Airalo, and $73.90 from Holafly. It's also the cheapest week at 7 days for $19.99 and the cheapest two weeks at 14 days for $27.99. The same eSIM covers more than 160 other countries at the same prices, which helps on a wider Southeast Asia trip — check Maya's country list for each stop.
Best for: Content creators, heavy video callers, and travelers who don't want to track usage. The tradeoffs: Maya sells no fixed-data plans and doesn't name an Indonesian network, and for most visitors 10–20 GB of fixed data costs less.

Here's how the major eSIM providers stack up for Indonesia and Bali coverage:
The same 10 GB, ten different prices
10 GB over 30 days is the cleanest way to compare providers side by side:
Ubigi is the cheapest 10 GB from a mainstream provider, but it runs on Indosat rather than Telkomsel — fine for Seminyak, Canggu, and Ubud, less so for the outer islands. Airalo names all three of Telkomsel, Indosat, and 3 and has the most polished app, but charges $21, $1.80 more than Yesim. For a trip of a week or less, SimOptions sells 10 GB for 7 days at $9.50 on Telkomsel and XL, and the MobiMatter marketplace lists an Indonesia-only 10 GB for $7.99 from third-party sellers, if you're comfortable with a lesser-known brand.
What about Holafly?
Holafly sells unlimited data only, on XL and Telkomsel, at the same prices it charges in most countries: $20.50 for 5 days and $73.90 for 30 days. That's $23.91 more than Maya for the same month, and it isn't the cheapest unlimited plan at any length we checked.
Which plan should you choose?
For most travelers on a 7–10 day Bali trip, 5 GB covers maps, messaging, Grab rides, and social media: $11.52 from Yesim or $12 from Nomad, both on Telkomsel — with more options on our full Indonesia comparison. Sharing a lot of photos and video? Yesim's 20 GB at $26.40 beats every unlimited plan on price. Want no limits at all? Maya's unlimited is $19.99 for a week.
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 providers now list 5G support, but outside Denpasar you'll mostly be on 4G/LTE, which is more than sufficient for travel. Nomad's fixed-data plans are 4G only.
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. Of the providers in this guide, Yesim, Nomad, Airalo, SimOptions, and Holafly name Telkomsel.
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 — 5 GB is plenty — Yesim sells it for $11.52 and Nomad for $12, both on Telkomsel. If you plan to video call frequently or share lots of photos and reels, go for 10 GB (from $16 at Ubigi, $19 at Nomad) or an unlimited plan: Maya's is the cheapest at $19.99 for 7 days.
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: Yesim, Nomad, Airalo, SimOptions, and Holafly all name Telkomsel; Ubigi and aloSIM name Indosat.
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. Unlimited plans don't need top-ups, though most slow down after a daily allowance (Airalo after 3 GB a day, Nomad after 2 GB). You can also buy a second eSIM if your provider doesn't offer top-ups.
