A Deeper Apple Patent details methods and support for Multi-SIM and eSIM for iDevices and Macs
Back in September 2018 Apple's SVP of Worldwide Marketing introduced eSIM and Dual SIM with iPhone XS and XS Max. The video below presents that part of the keynote outlining these new technologies. The video is set up to start at the 1:17:30 mark of the keynote. You could stop it 2 minutes later when that segment is over.
In January of this year Patently Apple posted a report titled "Apple's Patent covering iPhone eSIM and Dual SIM Reveals that it was first filed in China."
Today the US Patent & Trademark Office published a patent application from Apple that generally relate to wireless communications, and more particularly, to methods and apparatus to support access to services for multiple subscriber identity modules (SIMs) simultaneously by a single-radio, multiple SIM (multi-SIM) wireless device. It's a much deeper patent than the one that we covered back in January.
