i swear i have tried everything.. here goes..

i bought my e71 in aus just before i come home for optus. so i come home and get a vodafone sim card. everything works brilliantly except for sending and receiving pxt. i have had settings sent from vodafone and that didnt work, so i tried the settings from nokia, no luck. i have rang both vodafone and nokia and it might just be miscommunication i dont know but no help there. even went into vodafone. ive googled and searched on geekzone for a similar problem but no luck. and i have tried using my sim in a mates phone to send a pxt to myself (her phone was pretty old tho so that might be why it didnt work)

any ideas would be appreciated
