Thailand eSIM: the biggest gap is on the monthly plan

Bangkok, Phuket and Krabi are places where a stay can stretch to three or four weeks, so the monthly plan matters most. In our 22 October 2026 check Thailand was the cheapest destination in our list at Airalo, with unlimited data from 9.50 dollars for three days on the True network.

The gap with Holafly grows with length: 21 dollars against 27.50 for a week, then 49 dollars against 73.90 for 30 days, a difference of almost 25 dollars. For a month of island hopping that is the clearest price gap we found between the two providers in this batch. Still, compare the length you really need; there is no point paying for a month on a ten-day trip.
