Couldnt make calls, SMS wouldn't work and people couldn't ring me..

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.. :)
