Why use an eSIM in Cuba?
Cuba is the one Caribbean destination where getting online is a genuine part of trip planning rather than an afterthought. There is a single mobile operator, ETECSA, and everything — local phones, visitors, roaming connections — runs on that one network. For years travellers managed with Wi-Fi cards bought in queues and used in public squares, which is why Havana's parks fill with people holding phones up. Having your own data changes the rhythm of a trip that otherwise depends on arranging casas particulares, classic-car drivers and Viñales day trips through whoever you can reach. A travel eSIM installed before you fly is set up before you reach José Martí (HAV) or Varadero (VRA), with no counter to find. See the plans above.
