Types of SIM Card Connectors

We cannot imagine a world without mobile phones. These little devices help us stay connected with each other in an age that is buzzing with digital noise.

But these mobile phones wouldn't mean a thing if they didn't come with SIM cards. SIM is short for Subscriber Identity Module and they are the lifeline for the mobile phones that we carry around.

A SIM card consists of a body and a number of connected receptacles for receiving and conducting terminals. These terminals are responsible for the electric signalling which is received by the SIM card.

Now this SIM card is held in place by a SIM card holder. These SIM card holders can be of various types depending on the design of the mobile phone. In this article, we will be discussing about these types.
