The ultra-small height can reach 1.5mm-1.2mm.
2) SIM card connector with movable support
This kind of card holder itself has a fixed sim card support, the support can realize the movement within the range of 180℃ through the rotating shaft, the card loading and unloading is convenient, and the design is also more convenient.
