I cannot get this USSD service to work on this phone.. It opens the first two menu's up succesfully,but thereafter it wont go any further and responds 'failed' Please,any help in this regard would be great, because I have to use this card like any other card...no mobile banking for me. Its a new phone the Samsung i600, so I cant understand why it will not work..because even very old phones can do this> Best wished Kevin ps Your service is gr8!
