Phuket, two weeks. Bought the plan before flying, just switched it on — worked on the beach and on tours.
Bangkok and Pattaya. Fast enough for video calls, navigation and Grab. Cheaper than an airport SIM.
Inland Samui the signal dipped, by the sea it was great. Instant QR, Galaxy S23.
QR arrived a minute after payment. Installed at home over Wi-Fi, data switched on automatically at the arrival airport.
Smooth checkout, QR in about two minutes. Not a single dropout during the trip.
Third purchase here. Pay, scan, go — still works every time.
