i-SIM Technology for Smartphone

i-SIM:

Smartphone manufacturing company ‘ARM’ has been striving to reduce the size of their devices. Now, the chip designer ARM has designed a new component called i-SIM which stands for integrated subscriber identity module that aims to pack SIM cards into the same chip as the processor.

The i-SIM assuredly takes up a mere "fraction of a millimeter squared" compared to current SIM cards. Naturally, as Smart devices have gotten smaller with the passage of time, packing increasingly powerful hardware inside them.

Difference between i-SIM and e-SIM:

e-SIM relies on a separate processor. Furthermore, it requires more space and can be dislodged easily but i-SIM no longer relies on a separate processor; nor does it demand a significant share of a device’s hardware footprint.

Why do we need to improve the design of SIM card?

We need to improve the design because an IoT and connected consumer devices continue to shrink, a physical SIM card occupies a relatively larger proportion of a device. This creates a design challenge for device makers that may need that space for an important feature.  

Benefits of i-SIM:

·         i-SIM can’t be dislodged but Physical SIM cards can be easily dislodged and damaged.

·         Theft can never clone and misuse your sim card because it is integrated in a system on a chip (SOC)

·         Tracking of mobile phone containing i- will be easier compared to normal sim card

·         Normal smart phones have ability to physically remove a card from a device makes it easy to steal, which happens countless times every day, around the world,but I sim can’t be removed because it is integrated in a mobile processor.

·         The space that i-SIM would free up could allow for larger batteries, even thinner phones, additional RAM capacity or simply more powerful mobile hardware overall down the line. Furthermore, card manufacturers could save quite a bit of money.
