Trip length is the first question and data size is the second. Our Thailand plans come in fixed sizes with fixed validity periods, so the right choice is usually the smallest plan that covers your days with some room to spare.
Seven days: start small
A long weekend or a short city stay needs little data: maps, ride apps, messages and a few photos. Our 1GB plan for 7 days costs $2.50. Many travelers find that enough when hotel and café Wi-Fi covers their evenings.
Fifteen days: the middle option
For a two-week trip with more ride-hailing and a few video calls, 3GB for 15 days costs $4.50. The 3GB plan for 30 days costs the same $4.50, so if your trip is 15 days long, you do not need to pay for the extra two weeks.
Thirty days: islands and longer stays
Longer stays and island hopping need more room. 5GB for 30 days costs $7.00, 10GB for 30 days costs $12.00 and 20GB for 30 days costs $20.50. Heavy users who stream on the beach can look at 50GB for 30 days at $67.50. Plan sizes are fixed, so choose the nearest size above your estimate.
A big plan is still not unlimited
Even a 50GB plan is a fixed amount of data, not unlimited. If you expect to go past it, buy a second plan rather than assuming it will never run out. We do not sell unlimited plans.
Coverage on the islands
Our Thailand plans run on TrueMove H and DTAC. Signal quality varies by location, and remote islands and national parks can have weaker coverage. Check the operator's own coverage map if you plan to spend much time away from the main towns.
