Each company offers slightly different coverage, data packages, and overall value.
This guide provides a Bali SIM card price comparison and helps you decide which provider best matches your travel style. We won’t include exact tariffs here—since they often change—but instead, we’ll focus on relative strengths, coverage, and what you can expect as a tourist.
By the end of this article, you’ll know how each provider compares, where to buy your SIM card, and why booking ahead through services like SIM Card Airport Bali can save you time and stress.
Why Compare SIM Card Providers in Bali?
Choosing the right SIM card in Bali isn’t only about the price. Other key factors include:
Coverage: Does the provider work well across tourist hotspots and rural areas?
Data Speeds: Can you stream videos, upload photos, and use maps without delays?
Convenience: How easy is it to purchase and activate the card?
Value for Money: Are the data plans sufficient for your trip length and usage?
Tourists often focus solely on cost but forget that weak coverage or slow internet can ruin their experience. Comparing providers ensures you choose a SIM card that matches your needs—not just your budget.
Telkomsel: The Coverage Leader
Telkomsel is Indonesia’s largest mobile network provider, and in Bali, it is widely regarded as having the best overall coverage. Even in more remote areas like North Bali or the smaller islands nearby, Telkomsel generally provides reliable service.
Strengths:
Strongest coverage in Bali, including rural areas and beaches.
Consistent 4G and growing 5G availability in urban centers.
Reliable for digital nomads or tourists exploring the whole island.
Considerations:
Typically priced higher compared to other providers.
Better suited for travelers who value reliability over savings.
If you’re planning to visit Ubud’s rice terraces, remote waterfalls, or Nusa Penida, Telkomsel ensures you stay connected without interruption.
XL Axiata: A Balance of Value and Coverage
XL Axiata is another popular option, known for providing a good balance between price and coverage. In major tourist destinations like Seminyak, Kuta, Ubud, and Canggu, XL performs reliably with fast data speeds.
Strengths:
Competitive pricing with decent data options.
Strong coverage in cities, towns, and main tourist areas.
Good performance for social media, video calls, and navigation.
Considerations:
Coverage may weaken in remote villages or mountainous regions.
Not always as consistent as Telkomsel in less populated areas.
For most average travelers staying in central Bali or along the southern beaches, XL offers an excellent balance of affordability and performance.
Tri (3): Budget-Friendly for Short Trips
Tri, often called “Three” or “3,” is known as a budget-friendly provider. Many young travelers, backpackers, or those staying in Bali for just a short holiday choose Tri because of its lower prices.
Strengths:
Typically the most affordable option.
Great for short stays or light data users.
Popular among budget travelers.
Considerations:
Coverage is weaker in rural and mountainous areas.
Data speeds can fluctuate during peak usage times.
Not ideal for travelers who rely heavily on stable internet.
If you’re spending most of your time in Denpasar, Kuta, or Seminyak and want to save money, Tri can be a suitable choice. However, if you’re venturing further, you may experience weaker signals.
Indosat Ooredoo Hutchison: Affordable and Practical
Indosat Ooredoo Hutchison (IM3) sits somewhere between Tri and XL in terms of pricing and coverage. It appeals to travelers who want affordability without sacrificing too much reliability.
Strengths:
Affordable plans with reasonable data allowances.
Good coverage in tourist hubs like Ubud, Sanur, and Nusa Dua.
Competitive with XL in terms of speed and availability.
Considerations:
Coverage in remote locations isn’t as strong as Telkomsel.
Data speeds can sometimes be inconsistent in rural areas.
Indosat is often chosen by travelers who want a middle ground: not the cheapest, not the priciest, but still reliable in most areas tourists visit.

Which Provider Should You Choose?
The decision comes down to your priorities:
Choose Telkomsel if… you want the best coverage everywhere in Bali, including remote areas.
Choose XL Axiata if… you want good value and strong performance in popular tourist regions.
Choose Tri if… you’re on a budget and staying mainly in city or coastal areas.
Choose Indosat if… you want affordable prices with reasonable coverage across most of Bali.
Each option has its pros and cons, but for most tourists, either Telkomsel or XL Axiata strikes the right balance.
Bali SIM Cards vs. International Roaming
Some travelers consider using international roaming instead of buying a local SIM. While convenient, roaming charges are often much higher than local SIM card prices. A local SIM provides:
Lower costs for calls, texts, and data.
Faster connection speeds on local networks.
Better reliability when moving around the island.
By choosing a Bali SIM card, you get the advantage of local rates and coverage designed for travelers.
Staying Connected Responsibly
While it’s tempting to stay online constantly, remember to enjoy Bali’s natural beauty, culture, and traditions. Use your SIM card wisely for navigation, communication, and safety—while also disconnecting to fully appreciate the island.
