Sim900 works at at commnad but sim800 doesn’t work at same at commnad

hi
I have two GSM modem with sim900 and sim800c module.
I installed an applet on the SIM card when inserting it into the sim900 modem and sending the at command At + csim = 42,“00a4040010AID”. The applet is easily selected and will answer.
But when I put the same SIM card in the sim800c modem and sending the at command At + csim = 42,“00a4040010AID”. just reply: +CME ERROR: unknown
sim800 modem responds to many At command but has problems with this command: At + csim = 42,“00a4040010AID”

First check in datasheet and confirm if the SIM800C supports that command or not.
