They are different in size. The S6 is a dedicated small card, the S4 is a Micro SIM card, and the S6 is a Nano SIM card.
Micro-SIM card, with the successive launch and exposure of Apple’s two new products, iPad and iPhone four generations, Apple continues to challenge the current industry standards. One of them is the small Micro-SIM card. -SIM card (SIM small card), replaces the standard size SIM card we usually use.

It can also ensure that the device will not be damaged when the user inserts it incorrectly, while providing reliable mechanical performance.
nano-SIM card, also known as the fourth mode element integrated circuit board, is a new generation of mobile phone SIM card. It is smaller and thinner than the micro-SIM in use. Apple and Nokia competed for design standards for the nano-SIM card and submitted designs in March 2012, awaiting a vote by the European Telecommunications Standards Institute. It was reported on September 13, 2012 that domestic operators purchased Nano-SIM cards, and the first batch was launched on September 21, 2012.
The nano-SIM card is a micro-SIM card for mobile phones, which is smaller than the Micro-SIM card. It only has an area of ??60% of the first-generation SIM card. Its specific size is 12mm x 9mm, and its thickness is also 12mm x 9mm. reduced by 15. The goal of nano-SIM is to replace the micro-SIM installed on iPhones. Its smaller size will free up space for increased memory, larger batteries and denser motherboard arrangements, helping mobile phone manufacturers to produce thinner and lighter products. products.
