Does anyone know the cheapest phone card to call Sri Lanka, but from a payphone ?

A lot of the cards offer cheap calls to Asia etc, but only from a mobile or a landline with a surcharge of 25p a minute from a payphone.

Alternatively - if this is not a good option, perhaps any ideas of cards that will work on a mobile from Sri Lanka to call back to Sri Lanka.

All help would be appreciated !

some cards have an 0207 number that u can use, which might not incur the 25p payphone surcharge (the reason for the surcharge is because the phonecard company pays for the cost of 0800 calls, whereas u pay for 0207 calls by putting coins in the slot). obviously, u need to pay for the 0207 call to london and that is 40p for the first fifteen minutes.

Just looked at the Post Office web site their international card is 13p min to mob/landline in Sri Lanka Plus a 20p min surcharge from a payphone.
