Mastering the Use of SIM Cards in Bali: A Guide for Transit Travelers


Staying connected is a common desire among most travelers, especially during a transit or stay in Bali. A reliable means of communication is key to a more comfortable and meaningful stay. This article aims to alleviate common concerns about connectivity for visitors to Bali and provide insights on how to identify the best SIM card options.

SIM Card Options in Bali

In Bali, there are primarily three SIM card options: prepaid SIM cards, e-SIM cards, and roaming through your home provider. Each option has its advantages and disadvantages, depending on convenience, cost, and the needs of travelers.

Prepaid SIM cards are the most accessible and economical option in Bali, offered by major local network providers such as Telkomsel, XL Axiata, Indosat, and others. They can be purchased at Denpasar Airport, tourist specialty stores, and street vendors.

e-SIM cards, offered in a digital format, are particularly convenient for travelers visiting multiple countries. They can be purchased online from providers like Holafly and WifiMap, offering easy plan changes and high flexibility.

Roaming with your home provider is the most convenient but also the most expensive option. It allows you to use your existing SIM card without needing to remember a new number.

Key Points When Choosing a SIM Card in Bali

Network Coverage and Speed

Coverage and speed vary across Bali, depending on your travel and usage areas. Checking the provider’s coverage map in advance is recommended.

Cost and Data Packages:

It’s crucial to choose the most cost-effective plan according to your usage and budget. Prepaid SIM cards generally offer better value.

Roaming offers convenience but tends to be expensive for data usage. In contrast, prepaid SIM cards may require initial setup but allow for economical plans based on data usage, reducing costs. Charges vary by country and data usage, but prepaid SIM cards may offer 1GB for a few dollars, whereas roaming can cost tens to over a hundred dollars for the same data usage. Prepaid SIM plans range from $10 to $50, allowing users to choose the best option according to their needs.

Travel Style

If your trip covers multiple countries, an e-SIM card may be more convenient. For visits exclusively to Bali, a prepaid SIM card is the most straightforward and economical choice.

Purchase and Activation

Prepaid SIM cards are available at Denpasar Airport’s arrival lobby and many tourist spots in Bali. e-SIM cards can be activated by scanning a QR code received via email after online purchase. If using your home provider, check if international roaming is enabled before departure.


The choice of SIM card in Bali heavily depends on your travel style and communication needs. Understanding the options of prepaid SIM, e-SIM, and roaming allows you to make the best choice for a comfortable stay. Even for short-term transit, securing the right means of communication can enhance your experience. This guide hopes to assist in planning your stay in Bali, ensuring you enjoy a worry-free trip and fully experience the island’s beautiful landscapes and culture.
