How much mobile data do I need for a 10–14 day trip to Sri Lanka in February?

For a 10–14 day trip to Sri Lanka, most travelers are comfortable with 5–10 GB of data, assuming typical usage like Google Maps, WhatsApp, email, social media, and some light browsing. If you plan to join a few video calls, upload a lot of photos and videos, or tether your laptop regularly, leaning toward 10 GB or more is safer. You can reduce data usage by downloading offline maps for Sri Lanka, saving playlists and shows over Wi‑Fi, and limiting HD video streaming on mobile data. Many eSIM plans allow top-ups, but it’s usually more cost‑effective to choose a slightly larger plan from the start than to buy multiple small add‑ons.
