SIM Card Dimension Guide

SIM card dimension guide

Here's GCT guide to SIM card dimension and thicknesses. We offer a large variety of SIM card connectors which accept the three main SIM card types.

Mini SIM, also known as 2ff or 2nd form factor was introduced in 1996 and has been the standard type for many years, there are a wide variety of connector products in the market, but with the emergence of Micro and Nano it’s now a mature product.

2003 saw the introduction of the Micro SIM card, also known as 3ff, or 3rd form factor. Micro SIM is the same thickness as Mini SIM at 0.76 mm, however it offers a much smaller overall package, the contact area remains exactly the same, but size is reduced by more than 50%.

Nano SIM was introduced in 2012 and is becoming more and more prevalent in the market. Nano SIM is also know as 4ff or 4th form factor. It’s even smaller and thinner than Micro SIM, with a 108 mm footprint, vs. 180 mm for Micro. However it is very small and can be fiddly for end users to handle.  We see that Micro SIM has longevity in the market, as although smaller it is more easily handled by the end consumer.

Global Connector Technology offer connectors for every SIM card type, with a variety of different styles, such as push-pull, push-push and hinged.
