What Is a Blank Sim Card?

The nano-SIM card is also called the fourth form element integrated circuit board, which is a new generation of mobile phone SIM card. It is smaller and thinner than the micro-SIM card being used. Apple and Nokia competed for the design standard for nano-SIM cards, and submitted a design proposal in March 2012, waiting for the European Telecommunications Standards Institute to vote. It was reported on September 13, 2012 that domestic operators purchased Nano-SIM cards, and the first batch was launched on September 21, 2012.

Nano-SIM cards are smaller and thinner than Micro-SIM cards and ordinary SIM cards. The nano-SIM card has a length and width of 12x9mm, which is better than a micro-

The SIM card (15x12mm) is reduced by 30%, and it is 60% smaller than the mini-SIM card (25x15mm). In terms of thickness, it will be about 0.67mm, which is 15% thinner than ordinary SIM cards.

First, use scissors and vernier calipers (high-precision instruments) to cut ordinary SIM cards into nano-SIM card sizes and shapes, and strictly control the accuracy.

Then, sand the ordinary SIM card to the thickness of the nano-SIM card with strict control of the intensity.
