Called Telecom who said the usual, reboot etc.. but to no avail
To cut the story short, had to wait till monday and went into a telecom store and was told "oh you need the new v2 sim as your old v1 sim has been disconnected"
Ohh really ? crikey.. Guess XT are lucky i persevered in wanting to fix it, i was *so* close to changing provider after all these outages .. why on earth would they do this without notification of some sort eg: txt a week before hand to say "hey go change your sim" grr ..how was i meant to know.
rant over.. :)
