Qualcomm integrates your mobile operator’s SIM into the SoC

It seems that the eSIM will have a very short life, and it is that we already have its successor, the iSIM. The most interesting of all is that this new way of interacting with the SIM card will facilitate the change of operatorAlthough the most interesting of all is that it will take up less space on the device. all of it reducing energy consumption.

For now, iSIM will be an exclusive feature of those devices that make use of the SoC Snapdragon 8 Gen 2. Specifically, Qualcomm has partnered with Thales to embed iSIM, or embedded SIM, within its SoC. Hence, it ends up taking up much less space compared to physical SIMs, not to mention eSIMs. In this way, the short-term future passes for removing physical SIMs solving the inconveniences that eSIM present today. For context, Thales is a mobile device security company.


“In essence, iSIM allows devices to connect to a mobile network without the need for a physical SIM card or an eSIM soldered onto a device motherboard (PCB).

Instead of using a separate physical SIM card, iSIM technology embeds SIM functions directly into the device’s hardware, allowing it to connect to the cellular network.”

The iSIM will be represented in all top-of-the-range smartphones with Qualcomm SoC

SIM size vs eSIM vs iSIM

Unlike eSIMs, iSIMs are located within the smartphone’s own main processor, the “SoC”. This implies taking up much less space compared to the slot to integrate the physical SIM cards. And even take up less space compared to the current eSIM solution.

In essence, the iSIM does not take up any additional space. According to Qualcomm, this reduces costs and improves efficiency from smartphone manufacturers. It also allows manufacturers create smaller and more compact devices.

“Together with the increasingly popular eSIM, Thales 5G iSIM offers device manufacturers and mobile operators even greater freedom to offer their customers effortless over-the-air connectivity and more exciting and accessible product designs,” said Guillaume. Lafaix, vice president of integrated products for Thales Mobile and Connectivity Solutions.

The most interesting of all is that iSIM consumes less power Regarding the eSIM. This means increasing the autonomy of mobile devices, not to mention IoT devices. Unfortunately, no concrete numbers were offered regarding energy savings. As stated by Thales, iSIMs support the same high-level security protections than the latest generation of eSIM.

“The new iSIM is fully compliant with the GSMA Remote SIM Provisioning standard, meaning your subscriptions can be managed remotely via any standard platform. The emerging iSIM form factor complements existing SIM and eSIM designs, and research suggests that the market share will grow to 300 million by 2027, representing 19% of all eSIM shipments,” according to consulting firm Kaleido Intelligence.
