When you say ‘customised AT commands’ do you mean ‘can I write an application with my own AT commands to output the information I want’? Short answer is no, the command set is defined and set in firmware.
You can get most of the information you have quoted below through these commands on the HL and MC cards although they are different sets. The MC is far more restrictive as it is designed primarily to work with the QMI interface and a Linux host.
