Ghost SIMs

Notes from a GrapheneOS Pixel user on SIM privacy. A SIM card has two identifiers, the ICCID printed on the plastic and the IMSI the network sees, and a phone adds its own IMEI on top. A removed SIM with no power cannot report its location, but the carrier keeps a record of the last cell it touched. GhostSims sells eSIMs and nano SIMs it says need no ID at checkout, plus de-Googled Pixel phones, with coverage in 180+ countries.
