What exactly is an eSIM and how does it function for travelers?

An eSIM, or 'embedded SIM,' is essentially a digital SIM card built directly into your phone. Instead of a tiny plastic chip you insert, the eSIM profile is downloaded and activated electronically. For travelers to Ecuador, this means no more fumbling with physical cards or finding local shops. You simply purchase an Ecuador Abroad plan, scan a QR code, and your phone instantly connects to local networks like Claro or Movistar, giving you data wherever your journey takes you, from the Galapagos to the Amazon.
