Talking about banking in Argentina reminds me of an old joke. Two Jews (or Catholics or Muslims, take your pick) are stuck on a desert island. They create three synagogues/churches/mosques. One for each of them and third that they can both boycott.
It isn;t always easy banking here, although in some ways (technologically) Argentina is ahead certainly of Canada and the US - its a hell of lot easier to pay my bills here - I just go to bank's web site and all my bills are with amounts owing and due dates. It is also easy to transfer money between accounts, even between banks.
That said, I suggest you talk HSBC BEFORE you leave, they are about the about the only bank that has a truly global operation with the various countries actually talking to each other. If anyone can help you out, they can.
That said, the authorities and the labyrinthine banking laws here never make any simple transaction easy. And the people at the local branhces generally know nothing, so they do nothing.
Welcome to South America. I do love it, but as a friend once said, its as if the Nazi's had been put in charge of the BBC during the Monty Python era: very, very funny, but deadly.
Good luck.
