What is Gleesim?
What is Gleesim?
Gleesim is a travel eSIM solution that replaces the physical SIM card with a digital profile installed directly on your smartphone. Once your destination is chosen and the plan purchased on the Gleesim website, you receive a QR code to scan to install the eSIM and enjoy a data connection abroad without changing card or opening a local line. The service offers plans for individual countries (such as Saudi Arabia, Turkey, the United States, France, or Japan), as well as regional and global offers allowing travel to several countries with the same eSIM. Plans are data-only, but they allow voice and video use via apps like WhatsApp, Telegram, or Skype. Gleesim's unique feature is full management via WhatsApp: purchase, delivery of the QR code, usage tracking, and top-ups are done through conversation, without a dedicated app, simplifying usage for travelers and pilgrims.
