Most mobile phones rely on a small card, known as the SIM card, which contains the phone number and enables calls and text messages. A SIM (Subscriber Identity Module) is a small chip that connects mobile phones to the cellular network. SIM cards are issued by telecom service providers and store essential information like subscriber details, network authorization data, etc.
With the evolution of smartphones, the size of SIM cards also changed. As mobile phones became increasingly thin and sophisticated, SIM cards also became smaller. From the different types of SIM cards, standard (full size), mini, micro, nano, or e-SIM, Nano-SIM is the most used and best SIM card size.
To use a SIM card:
Ensure you have the right fit for your mobile
Locate the SIM card slot (or SIM trays) on your phone
Insert your SIM card and turn on the device to set it up
