Hi All,
I used AT commands before to set MSISDN field in the Physical SIM card.
Example:
AT+CPBS= ?
+CPBS: “SM”,0,500
AT+CPBS=“ON”
AT+CPBS?
+CPBS: “ON”,0,3 OK
AT+CPBR=1
OK
AT+CPBW=,“+912345678”
OK
AT+CNUM
+CNUM: “”,“+912345678”,145
OK
Now for esim , I cannot set CPBS=“ON” so my question is, how can I set the MSISDN field to the eSIM ?
The AT+CPBS=? command may help with a list of supported phonebooks.
If “ON” isn’t listed, please query the currently enabled phonebook set with AT$QCPBMPREF?
If that command returns something like:
0 -- Slot 1 Global Phone Book
try setting the set to local phonebooks with AT$QCPBMPREF=1
I managed to reach a result
AT$QCPBMPREF=3
This will point to the local address book for SIM2 (Which is an eSIM in my case)
AT+CPBS=“ON”
OK
but the command AT+CPBW gave error. I doubt that the eSIM manufacture has set the write permission for the EF_MSISDN file to be “ADM” so only the Telecom Operator can change it.
The question is : How can I verify that the EF_MSISDN write permission is set to “ADM” ? Is there any AT command to know this ? Or any way arround ?
