/*
 * This module implements special commands for the grcard.cn card model
 * which is known in the Osmocom community as GrcardSIM2:
 *
 * https://osmocom.org/projects/cellular-infrastructure/wiki/GrcardSIM2
 *
 * The sample cards which Mother Mychaela received from Grcard in 2021-02
 * are GrcardSIM2, and so are historical sysmoSIM-GR2 and 30C3 cards.
