Best eSIM for Thailand 2026 — Australian guide
Thailand — cheap travel, even cheaper data
Thailand is one of the most visited destinations by Australians. Bangkok, Chiang Mai, Phuket, Koh Samui, Pai — wherever you're headed, reliable mobile data makes the trip smoother.
From booking Grab rides in Bangkok traffic to finding street food stalls on Google Maps to staying in touch with family back home, data is essential in Thailand.
Is roaming worth it in Thailand?
Short answer: no. Australian carrier roaming in Thailand costs $10–$15 per day. For a two-week trip that's up to $210 extra on your phone bill. Thailand has excellent, affordable local networks — there's no reason to pay Australian roaming prices.
Thailand's mobile networks
Thailand has two major networks — AIS and DTAC (now True Move H). Both offer excellent 4G and expanding 5G coverage in major cities and tourist areas. Coverage is strong in Bangkok, Chiang Mai, Phuket, Pattaya and Koh Samui. More remote islands and jungle areas may have slower speeds.
