In addition to physical SIM cards that store your carrier and contacts subscription information, for the past few years phone makers have been offering eSIMs built into phones to easily switch between providers without swapping a physical card. But chipmaker Qualcomm has a new way to exchange service digitally: iSIM, or embedded SIM, which could be a faster and cheaper alternative.
While eSIMs are installed on the silicon somewhere inside the phones, iSIMs are located directly in the processor, and should similarly let you digitally manage carrier profiles on the phone. According to Qualcomm, this results in lower costs and better efficiency, since iSIMs need fewer components and take up less space. That could make iSIMs more attractive to cheaper phones and other connected devices, such as tablets and wearables, the company said. press release.
Since iSIMs consume much less power than eSIMs, they would be ideal for IoT devices, according to a blog post by the cybersecurity firm. Thaleswhich co-developed iSIMs with Qualcomm.
The first chip to use iSIMs is Qualcomm’s Snapdragon 8 Gen 2 chipset. But Qualcomm hasn’t indicated whether higher-end Android phones that already shipped with the chip, like the Samsung Galaxy S23 series or the OnePlus 11, will be able to use iSIM.
Qualcomm did not immediately respond to a request for comment.
