drnewcomb2,
thanks for the quick reply. I brought an old Nokia 2g phone with me which did work for Internet when i just got off the flight with Movistar. Since then it won't even make a connection (mesaage is "connection not available") with Movistar or any other network.
thanks for the helpline number, will try that next. Was in a situation today with cancelled flights etc - exactly when it would have come in handy.
