What Does A SIM Card Do?

These little plastic cards fit into a phone to contact the network through your phone’s antenna. What they do and how they work are essentially the same question. Once the card is installed into your phone, you can connect to your network. These small cards store data such as your phone number, network configuration settings, and more. SIM Cards allow your phone to place calls, send SMS & MMS, and use mobile data. They also store configuration data for your phone number and some phones can save your contacts there as well. Calls, SMS, MMS, and Mobile Data all route through the wireless network using that little card.
