Imagine your SIM tray as a doorKeeper holder of something, whose design and structure can drastically affect the delivery, perception, and utility of the phone.

The SIM tray is custom made from good quality plastic or really thin metal so that it can endure standard wear and tear on maintaining the SIM card and memory card.

Durability: The materials should give the tray enough strength to withstand standard wear and tear. It is important to note that it must be handled with care to avoid damage.
