TonMobile leads the Thailand board with an average of 9.3, ahead of HelloRoam at 8.8, Nomad at 8.6 and Saily at 8.5.

Board questions
Why is TonMobile first on the board?
TonMobile scores highest on plan range, validity and payment: seven fixed plans from 1 GB to 100 GB, validity up to 180 days, and TON, Bitcoin, cards, Apple Pay and Google Pay. It scores lower on network transparency because the plan page does not name a Thai network.
Do providers pay for their position?
No. Positions follow the average of six criterion scores, and the criteria are public on the scoring page.

HelloRoam lists 10 GB for 30 days at $9.97, Nomad at $10, Sim Local at $10.25, Saily at $10.99, TonMobile at $11.00 and Jetpac at $11.50, as read on October 27, 2026.
