The phone is due to arrive with me today between 1 and 6, so lets see what happens here.
Yesterday I tried the SIM in another 9700 on Orange and it worked fine, so therefore there is no reason a replacement will not work for me.
So the clock is ticking again. I look forward to the arrival of the phone so I can call Orange back to discuss the closing up of this whole issue.
Fingers crossed, I will be back on the grid shortly.
