What makes an eSIM the best choice for Thailand?
Three things decide it: a price agreed before you fly, data that doesn't run out mid-trip, and a setup you can finish at home. A prepaid unlimited travel eSIM answers all three — from £2.35 per day in Thailand, with the QR code in your inbox seconds after ordering.
Long-stay day rates make month-long Thailand trips surprisingly cheap per day — 30-day plans get the deepest discount.
