Short codes are complicated in terms of cost, as when there is a "fee" it's usually because a specific amount is sent to the party who you send the text to.
Virgin does maintain a list (Here) but sadly it doesn't include 62111 (it should, It did previously on the VMB site), not sure why it's not in the new list.
PSA (Premium phone regulator) says they manage shortcodes, but don't list 62111 as being in the database - O2 also list it as being reseved and not in use.
Personally - this is just me, I never reply to any shortcode (5 or 6 digit number) because some can empty your bank account.
Carriers also sometimes block shortcodes (as you can use them to get a cheaper service for things like international calls or text), but perhaps I am going way beyond your original question :P.

I do not work for VM, but I would. It is just a Job.
Most things I say I make up and sometimes it's useful, don't be mean if it's wrong.
I would also make websites for them, because the job never seems to require the website to work.
