You just landed in Indonesia, and you need internet access immediately. Whether it’s for transportation, navigating to your hotel, or staying in touch with loved ones, having reliable mobile internet is crucial. You have two options: a local SIM card or an eSIM.
An eSIM offers instant connectivity right after landing, allowing you to activate your plan online without any hassle. However, a local SIM card might provide better coverage and cost savings, especially if you plan to explore beyond the tourist hotspots. Let’s dive into the best options to kickstart your Indonesian adventure!
Key Takeaways for Mobile Connectivity in Indonesia
- Choose an eSIM for immediate connection upon arrival; it’s hassle-free and quick.
- Opt for Telkomsel as your local provider for the best coverage and positive user sentiment.
- Saily stands out as the top eSIM provider with a high rating and excellent service.
- Be prepared to show your passport for local SIM registration; it’s a requirement.
- Expect significant savings with local SIMs, as prices range from $8 to $25 compared to international eSIMs starting at $4.
- For short vacations, consider an eSIM for convenience; for longer stays, a local SIM offers better value.
- In urban areas, coverage is reliable, but rural regions may have limited connectivity; plan accordingly.

Steps to Activate Your SIM or eSIM
Technical Assistance & Smart Maintenance
Avoid connectivity headaches with these essential tips for a smooth internet experience in Indonesia.
- APN Configuration: Set your APN to ‘internet’ for Telkomsel and ‘internet.xl’ for XL Axiata. Go to your phone’s settings, select ‘Mobile Networks’, then ‘Access Point Names’, and add or edit the APN.

Important Note: Check your balance by dialing *888# for Telkomsel or *123# for XL Axiata. You can also use their respective apps for real-time updates.
To extend your data validity, simply purchase a new data package through the provider’s app or website before your current plan expires.
