Most hotels, villas and cafes in Bali offer Wi-Fi. But measured data puts Bali's fixed-line internet among the slower connections in Southeast Asia's popular remote-work hubs, with roughly one in five tests failing to reach 25 Mbps download. On top of that, around 40% of Wi-Fi connections in Bali still run on the old Wi-Fi 4 standard. Mobile networks, by contrast, have become much faster over the past year. This guide uses speed data from Ookla and official guidance from Indonesian Customs to show how far you can rely on Wi-Fi in Bali and what to prepare for your own connection.
If you want maps and ride-hailing apps working as soon as you land, you can set up an Indonesia eSIM before you leave. Choose a data plan that fits your stay from Coral eSIM's Indonesia plans.
Wi-Fi in Bali: easy to find, but quality varies a lot
Bali is well known as a base for both holidays and remote work, and Wi-Fi is standard in accommodation, cafes and coworking spaces around the southern beach areas and Ubud. Finding a connection is rarely the problem. The speed and stability once you are connected is.
In September 2026, Ookla published an analysis comparing April to June 2026 data for 13 remote-work hubs in Southeast Asia, treating the whole province of Bali as one destination. Bali's fixed broadband, the line that feeds hotel and cafe Wi-Fi, ranked near the bottom alongside Jakarta.
- Median fixed download speed: 67.04 Mbps (Singapore 447.75 Mbps, Bangkok 317.02 Mbps)
- Share of fixed tests below 25 Mbps download and 3 Mbps upload: 22.1%
- Share of Wi-Fi connections on the older Wi-Fi 4 standard: 41.9%
A 67 Mbps median is plenty for maps, messaging and streaming. But falling below 25 Mbps in roughly one test out of five means the experience can change a lot by room and time of day, even within the same property.
Why Wi-Fi in Bali feels slow: the line and the equipment
The fixed line itself is not very consistent
Ookla looked beyond medians at the share of tests that clear a minimum speed. Bali's fixed connections combined a low median with a low share of tests clearing the bar, meaning there is little headroom in either speed or stability. Evenings, when many guests are online at once, are more exposed to congestion.
The Wi-Fi equipment is old
Ookla points out that Wi-Fi is the last step between a venue's fixed line and your laptop, so a fast line can still deliver a slow session. With 41.9% of Wi-Fi connections in Bali on Wi-Fi 4, even the newest phone or laptop only performs like a Wi-Fi 4 device when connected to a Wi-Fi 4 access point. A booking site saying "free Wi-Fi" tells you nothing about speed.
Mobile internet in Bali improved sharply in a year
Mobile networks tell a different story. In the same Ookla analysis, Bali's median mobile download speed rose 62.4% between Q2 2025 and Q2 2026, the largest increase among the 13 destinations.
5G is spreading too. The share of time 5G-capable devices actually spent on 5G reached 42.3% in Bali, up 25.0 percentage points in a year. That is still well behind Phuket (83.8%) and Bangkok (80.5%), so expect to spend a good part of your time on 4G.
Across Indonesia as a whole, Ookla's August 2026 index puts the median mobile speed at 83.62 Mbps download, 23.82 Mbps upload and 25 ms latency, and the median fixed speed at 84.19 Mbps download and 64.82 Mbps upload. Download speeds on mobile and fixed are roughly on par, so switching to your own mobile data when the hotel Wi-Fi is slow is a genuinely useful option.
When to use Wi-Fi and when to use an eSIM in Bali
Based on the data, it makes sense to treat venue Wi-Fi in Bali as a bonus and to rely on your own connection when you are on the move or doing anything important.
| Situation | Best connection |
|---|---|
| Streaming and photo backups at your accommodation | Hotel Wi-Fi (switch to eSIM if it is slow) |
| Ride-hailing, maps and messages on the go | eSIM (no Wi-Fi outdoors) |
| Video calls and work uploads | Keep an eSIM as backup and switch if Wi-Fi is unstable |
| Online banking and entering card details | eSIM (avoid public Wi-Fi) |
If you work on a laptop, you can also share your phone's connection by tethering. See how to use hotspot tethering with an eSIM. For longer stays based around cafes and coworking spaces, our eSIM guide for digital nomads may also help.
Using a local SIM in Bali: watch out for IMEI registration
In Indonesia, phones used with a domestic SIM card must have their IMEI (device identification number) registered. According to the official guidance from the Ngurah Rai (Bali) office of Indonesian Customs, foreign travelers are treated as follows.
- Using a foreign SIM on international roaming: no IMEI registration needed
- Using an Indonesian SIM for a stay of up to 90 days: register the IMEI at a mobile operator's store
- Using an Indonesian SIM for a stay of more than 90 days: register the IMEI via the Customs website or app (up to two devices per person)
In other words, buying a local SIM at the airport or in town means going through an in-store process. If you would rather skip that step on arrival, set up a travel eSIM before you leave and simply switch the line on after landing. Your phone needs to support eSIM and be carrier-unlocked (how to check whether your phone is unlocked).
Tips for using free Wi-Fi in Bali safely
Cafes and restaurants usually display the password or share it when you order. That is convenient, but, as with public Wi-Fi anywhere, the network is shared by strangers. Switch to your own mobile data before online banking, entering card details or logging into accounts, and watch out for fake access points with similar names. See our guide to free Wi-Fi security for more.
Bali also comes to a standstill on Nyepi, the Balinese Day of Silence. How connectivity works on that day, and what coverage is like in the hills and on the outer islands, is covered in our Bali and Indonesia eSIM guide.
Internet in Bali: frequently asked questions
Is hotel and villa Wi-Fi in Bali fast?
It varies widely by property. In Ookla's April to June 2026 data, Bali's median fixed download speed was 67.04 Mbps, and 22.1% of tests did not reach 25 Mbps download. A "free Wi-Fi" listing on a booking site does not tell you the speed, so it is worth having your own connection as a backup.
Can I work or join video calls from a cafe in Bali?
Usually yes, but there is little margin for stability. 41.9% of Wi-Fi connections in Bali run on the older Wi-Fi 4 standard, so even new devices may not reach their full speed. For important meetings, be ready to switch to eSIM tethering.
Is mobile internet in Bali slow?
It has improved a lot. Ookla's analysis shows Bali's median mobile download speed rose 62.4% in a year. Indonesia's national median mobile download speed was 83.62 Mbps in August 2026. Devices were on 5G 42.3% of the time, so expect to use 4G for a fair share of your trip.
Do I need to do anything to use a local SIM in Bali?
Yes. To use an Indonesian SIM, your phone's IMEI must be registered. According to Indonesian Customs, foreign travelers staying 90 days or less register at a mobile operator's store. If you keep using a foreign SIM on international roaming, no registration is required.
Is it safe to pay by card on free Wi-Fi in Bali?
It is not recommended. On networks shared with strangers, your traffic could be intercepted or you could be lured onto a fake access point. Switch to your own mobile data before entering card details or using online banking.
In Bali, treat Wi-Fi as a bonus and make your own connection the main one
Wi-Fi is easy to find in Bali's hotels and cafes. What the measured data shows, though, is that fixed-line speed and stability leave little headroom and much of the Wi-Fi equipment is old. Mobile networks, meanwhile, have become much faster in a year and are often the more comfortable option. Set up a travel eSIM before you leave, and use your own connection when the Wi-Fi is slow, when you are out and about, and whenever you do something important. That is the practical way to stay connected in Bali without frustration.
