I just found what was wrong, while watching what happened during a
connection under MSWIN. The Username and Password were supposed to be
both set to 'orange.ie', so I believed, especially since this was
supposed to be a short for 'Orange Internet Everywhere'. 'orange.ie' was
also the first choice that was being proposed by 'Sakis 3G'. I learnt
that it had to be changed to 'orange.fr'. Once this was done, I could
get connexions under Ubuntu without any further problems, whether using
'wvdial' or 'Sakis 3G'.
