/*
 * I, Mother Mychaela, am hoping to get some SIM cards from Grcard
 * that follow the protocol which the Osmocom community has nicknamed
 * GrcardSIM2:
 *
 * https://osmocom.org/projects/cellular-infrastructure/wiki/GrcardSIM2
 *
 * I haven't got these cards yet and may not get them for a long time,
 * hence the following code has been written blindly, untested.
 * If anyone in the community happens to have a sysmoSIM-GR2 card
 * that was once (aeons ago) sold by Sysmocom, please test this code!
