As handsets move more compactly, the number of SIMs in handsets has moved from kcal to medium-sized cards (MicroSIMs) to the now popular NanoSIMs, but in 2015, Apple started to do e-SIMs However, the concept of e-SIM card has been around for many years, but there is still no exact plan for promotion.

According to foreign media reports, the well-known chip design firm ARM announced the iSIM technology, that is, in the ARM architecture SoC-level integration SIM card, as mobile phones and operators to achieve a new link in communications.This set of design platform named Kigen , Including the Kigen OS system (GSMA-compliant), independent hardware blocks with secure encryption, etc. However, the first ARM-based platform to be used is the IoT IoT device, which may naturally target handset products in the future. By 2035, more than one trillion devices had integrated iSIM technology.

However, just as the promotion of eSIM is constrained by operators, iSIM also needs the cooperation of the latter, and the reason why operators do not want to promote e-SIM or i-SIM card is that if the service is introduced, Then its own customers will be a wide range of mobile operators for the competition will intensify.But the number portability network has begun to gradually implement the e-SIM card and i-SIM card implementation of the resistance will be reduced in the future Users can also use better wireless network.
