Question

Hello,
I am trying to use AT commands on RUT240 in order to select multi-IMSI on SIM cards.
Following the SIM vendor user guide, I am trying to send these types of AT commands:

gsmctl -A 'AT+CSIM=14,"00A40004023F00"'
gsmctl -A 'AT+CSIM=34,"00A404040CA0000000871002FFFFFFFF89"'
gsmctl -A 'AT+CSIM=56,"8010000017FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"'
gsmctl -A 'AT+CSIM=28,"80C2000009D30782020181900180"'
gsmctl -A 'AT+CSIM=40,"801400000F810301240082028281830100900102"'

But it seems that they do not have any effects.
Do you know if these AT commands are supported by RUT240?
Furthermore, there is some detailed information on the cellular modem used by Teltonika RUT240? Does it support SKT (sim toolkit commands)?

Thanks,
M
