ThirdSIM is a travel eSIM provider with data plans for 200+ countries and regions, from single-country plans to regional and global ones. Travellers can choose fixed data plans in a range of sizes and durations, or an unlimited day pass priced per day. The eSIM is delivered instantly by QR code and can be installed in about two minutes, before departure or on arrival. Plans are data-only, hotspot is allowed, and most plans can be topped up with more data and days without changing the eSIM. ThirdSIM is available on the web and in our iOS and Android apps, with 24/7 support, and an eSIM that has not been installed can be refunded within 180 days.
