Part 1: iPhone SIM Card Size

With the advent of technology every passing day, SIM cards have also evolved over the past years with their sizes and compatibility to various phones. Although SIM cards did maintain a thickness of just 1mm initially, it used to be as big as the size of credit cards but gradually, their size was reduced and made compact by shrinking the dimensions to the nano SIM cards available today. The modern-day SIM cards make it important for the contact footprint to be as small as possible without hampering any of the features of the embedded chip in a SIM card.

  • Nano SIM card is by far the smallest SIM card. It has the mere dimension of 12.3mm x 8.8mm x 0.67mm and can hold the same data as the earlier versions. It is the 4FF (Fourth Form Factor) SIM card with a reduced dimension of almost 42% of the original SIM card. The higher versions of iPhones starting from iPhone 5 use nano SIM cards.
  • The micro SIM cards are still popularly used by many high-end smartphones, even the original configurations of iPad, still use them. They are larger than the nano SIMs only by a slight percentage having the dimension of 15mm x 12mm x 0.76mm. For example, iPhone 4s still operates with micro SIM card.
