Written by the company

Bidaiesim is an online shop for travel data eSIMs: digital SIM cards you install on your phone before you travel, so you have mobile data the moment you land, without roaming charges or buying a local SIM. "Bidaia" means "trip" in Basque. We are a Basque project from Bilbao. We sell data-only eSIMs for more than 200 destinations: single countries, regions and worldwide plans. You can choose a plan with a fixed amount of data for the whole trip, or a daily plan with a set amount of data each day. We started Bidaiesim because comparing eSIMs was harder than it should be, with "unlimited" plans that slow down after a few gigabytes and little clear information. So we show everything before you pay: the data, the days, the local networks and the country your connection reaches the internet from. If a plan slows down after its daily data, we say how slow. Your plan starts counting when you first connect at your destination, not when you buy it. The eSIM arrives by email with its QR code, usually within a minute. You can add data from your order page, and if you have not installed the eSIM yet, you can cancel it there for a full refund. The price you see is the final price, in euros. The shop is in Spanish, English, Basque and Russian, and we answer help@bidaiesim.com within one business day.

Usé Bidaeisim para mi viaje a Vanuatu

Usé Bidaeisim para mi viaje a Vanuatu. Y me sorprendió con creces lo bien que funcionaba en un archipiélago tan remoto. Estuve en Espiritu Santo donde mi pareja tenia una SIM local y yo estaba usando Bidaiesim y al llegar a Port Olry, Espiritu Santo tenia que compartirle datos ya que ella no recibia señal y yo si. La recomiendo 100% tengo ganas de probarla en el Suroeste asiático pronto 🙌🏻

No puedo estar más satisfecho con Bidaiesim. Desde el primer momento, la experiencia ha sido excelente. Todo el proceso es rápido, sencillo e intuitivo, y se nota que detrás hay un equipo que se preocupa de verdad por ofrecer un servicio de calidad.

Lo que más destacaría es la profesionalidad, la atención al cliente y la facilidad de uso. Todo está pensado para que el usuario tenga una experiencia cómoda, sin complicaciones y con total confianza.

Es una maravilla encontrar empresas que apuestan por hacer las cosas bien y cuidar hasta el más mínimo detalle. Sin duda, una opción que recomendaría a cualquiera que busque comodidad, confianza y un servicio de primera.

¡Enhorabuena al equipo de Bidaiesim por el gran trabajo! ¡Totalmente recomendable!
