Understanding Wi-Fi and SIM Cards
Before we dive into the possibilities of using Wi-Fi without a SIM card, let’s first understand what Wi-Fi and SIM cards are.
What is Wi-Fi?
Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. Wi-Fi uses radio waves to transmit data between devices, and it operates on a specific frequency band. Wi-Fi networks are commonly used in homes, offices, cafes, and public hotspots to provide internet access to devices such as laptops, smartphones, and tablets.
What is a SIM Card?
A SIM (Subscriber Identity Module) card is a small card used in mobile phones and other devices to authenticate and identify the user to the mobile network. The SIM card contains information such as the user’s phone number, account details, and encryption keys. When a device is connected to a mobile network, the SIM card is used to authenticate the user and provide access to the network.
