How much eSIM data do I need for a 10‑day trip to Thailand in February?

For a 10‑day trip with typical usage—maps, ride-hailing apps, messaging, social media, and some web browsing—most travelers find that 5–10 GB of high-speed data is enough. If you plan to stream a lot of video, upload large numbers of photos, or work remotely with frequent video calls, consider 15–20 GB for more flexibility. You can always top up or add another eSIM plan if you notice you are running low during your stay.
