What is GoSIM?
What is GoSIM?
GoSIM is a prepaid eSIM provider for travelers, accessible on gosim.ch. An eSIM is a digital SIM card embedded in the phone: it is installed by scanning a QR code, without a physical card or store visit. GoSIM offers plans for one destination, as well as regional and global plans covering multiple countries (the exact list of countries is shown on each offer). Plans mainly focus on data, from 500 MB to unlimited, for 1 to 180 days. After payment, the QR code appears on the confirmation page and arrives by email in about two minutes. Validity starts when the eSIM connects to the destination network. A compatible and unlocked phone is required.
