Best SIM Card for Family Travel in Thailand

At BKK Airport: AIS Traveller SIM — 299 THB ($9) for 15 days, unlimited 4G + 100 minutes calls. Buy right after immigration; no setup.

Skip: Hotel WiFi-only plans. You'll need data outside.

For 2 weeks+: Get a local SIM with eSIM (Airalo app) before you fly. $15 covers the whole family if everyone has a recent iPhone.

Hot tip: Set up Google Family Sharing before the trip — everyone's location visible at all times.
