im sorry but i dont know, i think its best to contact customer service or have a visit to ur nearest o2 shop and make inquires on this matter....
No problems. I usually buy a £5 credit with a 3rd party provider (Story Telecoms) which means I can call the Phils for about 8-10 pence per minute by dialing a landline number in London. I'm quite happy with this arrangement anyway
