Unfortunately @deejay Dixon, mobile number transfers in the UK don’t happen immediately. 

Your switch happens sometime between 8am - 10pm, on the date it was scheduled. 

You’ll know iD have started work on your switch when your old O2 SIM card stops working.

When I switched to iD my old SIM stopped working at ~11am, and the number I was keeping started working with my iD SIM at ~3pm.
