Era of Physical SIM Cards Is Coming to an End

Qualcomm has teamed up with Vodafone and Thales to introduce a new integrated SIM (iSim) which is an alternative to eSim and physical SIM cards.

The iSim is basically a SIM that will be installed in the processor of the device which will not require replacement of physical SIM in phones and will be able to use larger batteries, more memory and other components.

All three companies demonstrated the concept of iSim on Samsung’s Galaxy Z Philip 3.

A new type of SIM card directly integrated into the processor has just been tested by Vodafone, Qualcomm and Thales. To save even more space and connect more devices to the mobile network.

The SIM card continues to evolve. After the eSIM, this SIM card directly integrated into the terminal, it is the turn of the iSIM to emerge. This time it is a question of soldering it to the main processor, which would avoid maintaining a separate chip as in the case of the eSIM and would make it possible to eliminate the space which was devoted to it.

A first proof of concept

Manufacturers have been talking about it for several years now. ARM was betting on it as early as 2018. The technology, standardized by the GSMA, did not emerge quickly. Qualcomm announced that its Snapdragon 888 5G mobile platform supports iSIM last August. And he has just carried out a proof of concept in Europe with the British operator Vodafone and the SIM card specialist Thales.

It was carried out with a Samsung Galaxy Z Flip 3 5G device and therefore the Snapdragon 888 5G platform, but also the Thales iSIM operating system in Samsung’s European R&D laboratories on the Vodafone network.

The expected benefits are obviously space saving and better system integration. Qualcomm also claims that it would improve the design, performance and memory capacities of the terminal. Finally, there is the promise, thanks to the iSIM, to connect a greater number of devices to the mobile network such as connected objects and wearables.

At the IT level, operators will continue to provision the card remotely using the infrastructure already in place for the eSIM. No smartphone manufacturer has yet announced an iSIM compatible device.

ISim is based on standard eSim but there is a fundamental difference.

E-SIM requires a separate chip that processes the data but the main feature of i-SIM is that it eliminates the need for extra space for SIM services while all the benefits of e-SIM such as the use of remote SIM Are part of


the new standard will also allow a wide variety of devices, such as wearables, laptops, tablets, VR headsets and IoT devices, to benefit from an active data connection.

Snapdragon 888 processor for Galaxy Z Philip 3 for iSim was modified and then tested on Vodafone network.

According to Qualcomm, better performance, increase in memory capacity and better system integration will be enabled from iSim.

It is unknown at this time what he will do after leaving the post.
