Popular Thẻ SIM in Indonesia

For your trip to Indonesia, we recommend choosing a local SIM card, eSIM, or renting a portable WiFi device. Local SIM cards and eSIMs are convenient to install directly into your phone and offer stable internet, ideal for solo travelers or those with light data usage. Portable WiFi devices allow multiple users to share the connection, fulfilling group needs with a single device. You can select the most suitable plan based on your travel duration, data consumption, and the number of people traveling together. Pre-booking through KKday offers benefits like Chinese customer support and flexible cancellation, avoiding language barriers when purchasing locally.

Setting up an Indonesia eSIM is typically done by scanning a QR code. After purchasing your eSIM, you will receive activation details. Before or upon arrival in Indonesia, scan the QR code or manually enter the activation code via your phone's settings to configure the eSIM as your mobile network. Remember to enable mobile data roaming for this eSIM in your phone's settings and ensure the correct APN settings are selected. The advantage of eSIM is that it eliminates the need for a physical card, offering a convenient and quick experience without the hassle of swapping SIM cards.

Mobile network coverage is generally good in major Indonesian cities like Jakarta and Surabaya, as well as popular tourist destinations such as Bali. Most areas offer stable 4G service, with some major cities even providing 5G signals. However, in more remote islands or mountainous regions, network signals might weaken or become unstable. It's advisable to check the network status of your intended destinations beforehand or opt for a telecommunication provider with wider coverage to ensure smooth connectivity during your trip.

The primary telecommunication providers in Indonesia are Telkomsel and XL Axiata. Telkomsel is generally known for its extensive network coverage, performing relatively stable even in remote areas, making it a popular choice for many travelers. XL Axiata, on the other hand, often offers competitive pricing and good network speeds in specific areas, such as major cities and tourist spots. Travelers can choose a suitable plan based on their main travel regions and their requirements for network stability.

Indonesia's rainy season typically runs from November to April. While network infrastructure is usually designed to withstand weather changes, extreme heavy rain or thunderstorms may temporarily cause slight disruptions to mobile network signals in some areas, leading to slower speeds or instability. This is less common and has minimal impact in major cities or tourist areas. During the rainy season, it's recommended to have offline maps ready or download media content in advance as a backup, ensuring a smooth journey.

When traveling to Indonesia, apart from purchasing a local SIM card, there are several other mobile internet options. Travelers can consider using an eSIM, which requires no physical card and can be activated by scanning a QR code, offering convenience and speed. Renting a portable WiFi hotspot is also a popular choice, allowing multiple people to share the internet connection, which is ideal for group travel. If you don't use the internet frequently, international roaming services offered by some telecommunication providers are another option, but be mindful of their fee structure. You can assess these based on your data needs and convenience.

Upon arriving in Bali, you can purchase Indonesian SIM cards at telecom counters in the airport, telecom stores in the city, convenience stores, or some souvenir shops. Buying at the airport is usually convenient, but selection might be limited. If you wish to save time searching and communicating upon arrival, we recommend pre-booking through KKday. Pre-booking via KKday provides access to Chinese customer support and flexible cancellation, ensuring you can quickly obtain and activate your internet service upon arrival.

After purchasing an Indonesian SIM card, the activation process typically involves the following steps. First, insert the SIM card into your phone. Then, according to Indonesian regulations, you may need to provide identification documents such as your passport for real-name registration. Once registration is complete, the SIM card will usually activate automatically, or you may need to send a specific SMS to activate your data plan. After activation, it's recommended to immediately test the network connection to ensure you can go online normally. If you have any questions, seek assistance from the staff at the point of purchase.

The cost of using international roaming services in Indonesia primarily depends on the roaming plan provided by your original telecommunications operator. Generally, international roaming charges are higher than purchasing a local SIM card or eSIM. The cost calculation may include data usage, calls, and SMS, and charges can be based on daily rates or data volume. We advise you to check the latest international roaming plans and fee details with your own telecommunications provider before your trip. Evaluate if it aligns with your internet usage habits and budget to avoid high charges.

Estimating your mobile data needs for your trip to Indonesia mainly depends on your usage habits and travel duration. If you only use it for navigation, instant messaging, browsing social media, and checking information, a small amount of daily data is usually sufficient. However, if you frequently watch online videos, make video calls, upload large amounts of photos, or need to handle work, it's advisable to choose a plan with a larger data allowance. You can review your typical mobile data usage to select a suitable plan. If you're concerned about insufficient data, you might consider plans with top-up options or flexible extensions.
