I used to buy SIM cards at the airport. Then I bought them at mall shops. Now I just use eSIMs—easy-peasy and better value. Download and set up at home. On arrival: connect to free airport Wi-Fi and start the eSIM.

### 📱 SIM CARDS AT AIRPORT/7-ELEVEN/MALLS

**Location:** After exiting arrivals, booths immediately visible. But ignore these! Wait until you’re at a mall or 7-Eleven – cheaper.
