AT+CGLA=? not supported on EM7590 and AT+CCHO returns error

With this fix I can report that everything works!

So in short:

  1. AT+CGLA=? isn’t supported (Please fix your documentation)
  2. SIMLPA doesn’t allow AT+CCHO to work
  3. Disabling SIMLPA requires AT!ENTERCND=“A710” followed by AT!CUSTOM=“SIMLPA”,0
  4. After that AT+CCHO and AT+CGLA= (but not AT+CGLA=?) works

I can confirm that with this instructions and some hacking into lpac to make it not check for AT+CGLA=? I can list the profiles in the eSIM I use
