 /*
- * I, Mother Mychaela, am hoping to get some SIM cards from Grcard
- * that follow the protocol which the Osmocom community has nicknamed
- * GrcardSIM2:
+ * 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
  *
- * 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!
+ * The sample cards which Mother Mychaela received from Grcard in 2021-02
+ * are GrcardSIM2, and so are historical sysmoSIM-GR2 and 30C3 cards.
