Been scouring the forum now for sometime & starting to develope square eye syndrome!.... Can anyone please answer a simple question for me please! Being, when I call internationally, do I have to hang up after 30 mins or 60 mins in order to avoid being surcharged? (presuming I am still within my 300 mins as contracted of course). Seen many conflicting threads,some stating 30 mins,others stating 60? However these were some years old,nothing recent.
