Please forgive...I have very little idea about the big computer world out there and have only recently switched to MAC. I was told that if I wanted to access the web from my ipad away from home I would need a sim card - OK - purchased - inserted - never used of course because it is sometimes months in between use of my ipad.... I have just charged it up ( attached to itunes) and it is telling me( top LHS )- SOS only..what is this?? Does this mean the sim card has run outta juice?? Secondly it will not recognise my usual bigpond account password....I have delete the account on the ipad and started it up again but no joy What am I doing wrong...I used to be able to get all my bigpond mail and now NOTHING!!
