For some reason i cannot access the Easyphone features on the Slingshot website. At first i thought it may have been Adblock stopping it, turned that off but still no go.
Detruire: Are you trying to access it from a Slingshot connection? If not, it's probably because they block non-Slingshot connections from accessing that page for some silly reason. (Access from other NZ ISPs, please. )
