What is SimFuse?
What is SimFuse?
SimFuse is a solution for comparing and purchasing travel eSIMs. It presents data plans by destination, then delivers an eSIM profile to install on the compatible device after payment. The service offers local, regional, and global plans, with variable data volumes depending on the country or zone. Installation is guided within the app, and the eSIM works alongside the physical SIM card to keep the main number for calls and SMS. Since it is a data-dedicated eSIM, internet connection passes through SimFuse while the usual line remains active on the phone if the user wishes.
