Staying connected in Bali is essential, whether you are navigating through the island, booking transport, or sharing your adventures online. While most hotels and cafes offer free Wi-Fi, getting a local SIM card is the smartest way to ensure reliable internet and call access during your stay.
But with so many options available, which SIM card should you choose in Bali? This guide breaks down everything you need to know, from the best providers and packages to where to buy one and what to expect.
Why You Should Get a SIM Card in Bali?
While international roaming is convenient, it can be extremely expensive. Buying a local SIM card gives you access to affordable data, calls, and texts, whether you’re staying for a few days or several months. It’s especially helpful if you’re planning to travel outside major tourist hubs, where Wi-Fi may be limited or unreliable.
Top SIM Card Providers in Bali
1. Telkomsel
Telkomsel is widely regarded as the most reliable SIM card provider in Bali, especially if you plan to explore beyond the typical tourist zones. Its strongest advantage is nationwide coverage, you will get a strong 4G signal in urban areas like Canggu, Ubud, and Seminyak, as well as more remote destinations like Amed, Sidemen, or even Nusa Penida. This makes it ideal for long-term travelers, road trippers, and anyone needing stable internet on the go.
However, Telkomsel is also the most expensive option among local providers, and while you do get premium reliability, budget-conscious tourists may find it a bit pricey. Additionally, the SIM registration process might be confusing if you are not fluent in Bahasa Indonesia, though staff at official stores and airport counters are usually helpful.
2. XL Axiata
XL Axiata strikes a good balance between cost and performance for most visitors to Bali. The provider offers affordable data packages and solid coverage across popular areas like Denpasar, Uluwatu, Seminyak, and Ubud. If you are a digital nomad or remote worker staying mostly in South and Central Bali, XL is a practical and budget-friendly choice.
One of its main advantages is the easy top-up system and various prepaid data bundles tailored for short-term stays. However, coverage tends to weaken in Bali’s rural areas and mountains, such as the northern coast or less-touristy inland villages. While not as powerful as Telkomsel in remote zones, XL still serves the needs of most urban and semi-rural travelers very well.
3. Indosat Ooredoo (IM3)
Indosat Ooredoo, commonly branded as IM3, is known for its affordable and generous data packages, making it a favorite among budget travelers and younger tourists. It performs well in major towns and beachside areas like Kuta, Legian, and Canggu, and its activation process is generally fast and foreigner-friendly. IM3 often offers promo data plans with large GB allowances at competitive prices.
The downside is that the signal can be inconsistent outside city centers, especially in mountainous regions or coastal villages far from Denpasar. Data speeds may also drop during peak hours. Still, if your plans don’t involve much remote exploration and you want a cost-effective SIM card with decent internet, Indosat is a great pick.
4. Smartfren
Smartfren is a lesser-known option among international travelers but is still used locally due to its competitive pricing and internet-focused plans. Its biggest advantage is affordability, especially for tourists who only need data and don’t plan to make local calls. Smartfren offers packages with large data quotas and no-frills access for casual use like messaging, browsing, or social media.
However, the provider has limited coverage, primarily focused on urban areas such as Denpasar, Sanur, or Kuta. It may not work in remote destinations, and some foreign phones may not be compatible without prior unlocking or frequency support. For travelers staying within the main towns and relying mostly on data, Smartfren is an economical alternative, but not suitable for adventurers heading off-grid.

Where to Buy a SIM Card in Bali?
There are a few safe and convenient places to purchase a SIM card:
1. At the Airport (Ngurah Rai International Airport)
Once you arrive, you’ll see several official booths for Telkomsel, XL, and IM3 in the arrivals area. Staff usually speak English and help with SIM activation. However, prices here are typically higher than in town.
2. Local Mobile Shops and Convenience Stores
Shops in Canggu, Seminyak, Ubud, and Denpasar often sell SIM cards at more affordable prices. Look for authorized resellers or mobile phone stores. XL and Telkomsel outlets usually provide assistance with registration and choosing the right data plan.
3. Official Provider Stores
If you want to ensure your SIM card is activated properly, visit an official store like Grapari Telkomsel or XL Center. Bring your passport, as ID is required for activation in Indonesia.
4. Online Pre-Order (eSIM or Physical SIM)
Some travelers prefer to order an Indonesian SIM before arrival through platforms like Klook or Airalo (for eSIMs). This is ideal if you want immediate access when you land, although eSIM compatibility depends on your phone model. Make sure your phone is supported eSIM card before you buy it.
How Much Does a SIM Card Cost in Bali?
Prices vary depending on the provider and package, but here’s a general range:
- Basic tourist package with 10–25GB data: IDR 100,000–250,000 (~$6–$15).
- Unlimited or high-data plans (30+ GB): IDR 200,000–400,000 (~$13–$26).
- eSIM options (via app): usually priced in USD, starting from $7–$20.

What Documents Do You Need?
Indonesia requires SIM card registration for both locals and tourists. To buy and activate your SIM, you’ll need to:
- Show your passport.
- Register your SIM card with a local phone number and name (done by the shop staff).
- Wait a few minutes for the process to complete.
If you don’t speak Bahasa Indonesia, it’s best to buy from stores that are used to handling tourists.
Which Bali SIM Card Is Right for You?
Choosing the right SIM card in Bali depends on your travel style and where you’ll be spending most of your time. If you’re exploring the island in-depth, Telkomsel is the most reliable. For urban stays in places like Canggu or Seminyak, XL or Indosat offer great value. If you only need internet and don’t plan on moving around much, Smartfren or an eSIM could be your go-to.
Whatever you choose, having a local SIM will make your trip smoother, from calling a Grab to finding the nearest warung. Just be sure to activate your SIM at a trusted store and check the coverage map if you are headed off the beaten path.
