Nano Sim for iPhone5 | Size matters | Quick Guide to Nano Sims
When the GSM network first appeared, mobile devices resembled bricks or even briefcases, and SIM cards were the size of credit cards. The subsequent miniaturization of the phones led to the standardization of smaller SIMs, the Plug-in SIM, and later the Mini-UICC also known as 3rd form factor (3FF). With the introduction of Apple’s iPad, the 3FF, or the Micro-SIM as it was then called, established itself widely in the market. Nevertheless, the trend towards miniaturization of the SIM card is still not over.
The latest form factor which is currently in discussion at ETSI (European Telecom-Communications Standards Institute) is the 4th form factor (4FF) or Nano-SIM. Measuring 12.3 x 8.8 mm, the Nano-SIM is about 30 percent smaller than the Micro-SIM. Even the thickness (0.7 mm) of the card has been reduced by about 15 percent – a tremendous
The Nano-SIM offers device manufacturers the crucial advantage of freeing up extra space for other mobile phone components such as additional memory or larger batteries. Popular smart phones in particular have to strike a balance between the need for components that are more powerful but bulkier and a slim design.
The reduced volume of the 4FF gives manufacturers the opportunity to produce devices that are thinner and more appealing.
