Thanks to John G he's been a great help.
This new post is just as an update, not a solution im afraid, so here's my progress...
Got a new SIM from Orange, worked fine for about 3 weeks, then the texts started coming again... they are fairly regular now, and Im sure they affect the performance of the phone too. Does it affect others users phone performance? Would be interested to know...
