Before SIM cards were introduced, mobile phones connected to cellular networks using a system called "fixed identification." Users were assigned a unique phone number that was tied to the device itself, rather than to a removable SIM card. This meant that the phone's identity and subscriber information were hardcoded into the device, making it less flexible and portable compared to the SIM-based system that followed.
