Sky Mobile International Saver

Bargains25

I’m considering adding Sky Mobile’s International Saver £4/ month and would like to clarify call costs whilst overseas.  
If I was in say, New Zealand, and phone a New Zealand phone number, using their full code, as if phoning from the UK, would I benefit from reduced price per-minute calls of 5p a minute, 10p per text?  
Does anyone have experience of using Sky's International Saver whilst overseas?

Hard to work out what this has to do with water bills!
