The first crucial step upon arrival in Sumatra is to register your phone. This process must be completed at the airport in Medan, specifically after immigration and before you exit the terminal. Phone registration is mandatory to ensure your device works with local SIM cards. If you skip this step, your phone will not function with an Indonesian SIM card. Make sure you have your passport and phone ready for the registration process.

To get a SIM card in Sumatra, it’s convenient to start at the airport where drivers can take you to a nearby shop. Telkomsel is highly recommended for its extensive coverage and fast internet, even in remote areas like Bukit Lawang. While Telkomsel is generally the best option, having Axis as a backup can be useful during occasional power cuts, because Telkomsel normally doesn’t work when there is a power cut. You can also purchase SIM cards in Bukit Lawang, ensuring you stay connected throughout your journey. Just make sure, your phone is already registered.

For added convenience, you might consider using an eSIM. An eSIM is an embedded SIM technology that allows you to activate a mobile plan without using a physical SIM card. Many modern smartphones support eSIMs, and they can be a great option for travelers who want to avoid the hassle of swapping physical SIM cards. Check if your phone supports eSIM and if your preferred provider offers this service.
