What is eSIM?
eSIM (embedded SIM) is a digital SIM built into your phone. No need to buy a physical SIM card at the airport. Just purchase online, scan a QR code, and you are connected instantly. Most modern smartphones (iPhone XS+, Pixel 3+, Samsung S20+) support eSIM.

Tips Before You Buy
- 1. Check if your phone supports eSIM and is SIM-unlocked.
- 2. Buy and install the eSIM before departure — some require WiFi to activate.
- 3. Screenshot the QR code in case you need it offline.
- 4. For China, most eSIMs do NOT bypass the Great Firewall — you still need a VPN.
- 5. Compare data amounts: 1GB lasts ~7 days for light use (maps, messaging).
