Buying at the airport is convenient but costs the same as in the city. 7-Eleven and dedicated carrier shops often have the same prices โ the airport just saves you going out of your way. Pick it up on arrival and be online within minutes.
Most airport counters give you a free SIM ejector pin. If you're switching at a 7-Eleven, grab a pin or use a thin paperclip. Modern iPhones also accept a thin fingernail in a pinch.
Good news: all tourist SIM plans allow hotspot tethering. You can share your data with your laptop, tablet, or travel companion's phone. Just note that heavy tethering will eat through your data faster.
If you're using an Airalo eSIM, install and activate it before you get on the plane โ not at the airport. Once activated, your Thai number will be live the moment you land, with no queuing at the airport counter.
Airalo eSIM plans are data-only (no voice). If you need to make calls, use WhatsApp, Line, or FaceTime over data. Thai locals and businesses are very accustomed to WhatsApp and Line.
Koh Tao and remote islands can have spotty coverage regardless of carrier. AIS and True Move perform best. Expect occasional dead zones in jungle areas โ that's part of the adventure. Download offline maps on Google Maps before heading off-grid.
Skip the airport queue entirely. Buy your eSIM from Airalo, activate it at home, and be online the moment your flight touches down in Bangkok.
