The blog post discusses using a physical SIM to provision eSIMs on devices that only accept physical SIMs. The author purchased a bundle from 9eSIM, including a SIM card, smartcard reader, and adapter. They found that using the original SIM packaging made it easier to use the smartcard reader. The author successfully added and switched eSIM profiles using both Android and Linux. They also tested out free test eSIM profiles. The post provides detailed instructions on using the lpac command line tool on Linux and the EasyLPAC GUI for eSIM provisioning. Ultimately, the author was able to successfully use an eSIM on a physical SIM on a Debian laptop. The author mentions interest in trying other eSIM options, like the Sysmocom SIM.
