For many travelers, a local Indonesian SIM card is essential – whether for using Google Maps, staying in touch via WhatsApp, or quickly accessing information on the go. The good news: You can now buy a SIM Card at Medan Airport (KNO), it’s now easier than ever to get connected right after you land.
New Counters for a SIM Card at Medan Airport
Recently, several official SIM card counters from well-known providers have opened in the arrival area of Kualanamu International Airport (Medan):
- Telkomsel – known for the best coverage, even in remote parts of Sumatra
- XL Axiata (XL) – affordable packages, reliable signal in urban areas
- Tri (3) – very low-cost data options, great for short trips
The booths are located just after the exit, between terminal and train station. They’re easy to spot by their bright branding, and most staff speak basic English.
Which SIM Card Is Best for Your Trip to Sumatra?
| Provider | Best for… | Benefits |
|---|---|---|
| Telkomsel | Jungle & rural regions (e.g., Bukit Lawang, Toba) | Best signal coverage, even in forests |
| XL Axiata | Cities & urban travel (e.g., Medan, Padang) | Good price-performance ratio |
| Tri (3) | Budget travelers & short stays | Cheapest plans, easy setup |
Our tip: If you’re heading to remote areas like Gunung Leuser National Park, we recommend Telkomsel. For urban travel, XL or Tri are also suitable.
