hi are 0500 phone numbers free to call?

They're free.

I've had a look at this for James. We don't see call data for 0500 calls - just the same as 0800 so these are always free. I see calls going through on 055 & 056 - there are all rated @ g21:
g21 on new call plans:
Setup fee: 13.87p
Daytime: 4.99p per min
Evening: 2.04p per min
Weekend: 1.20p per min

I'm not sure about 055, but 056 numbers are VoIP so would normally be chargeable calls from a land line.
