Default [Q] How to extract APN settings from a locked phone?

As the subject says. Anyone know how to extract APN settings from a locked phone? I tried "APN Backup & Restore" but seeing Softbank has locked down the settings part I cant extract info, same goes for "Sbm4GSimInfo", it just returns blank fields.

I need this info as I want to buy a Nexus 5 or HTC One.
