The call forwarding on iphone does not load. Tried Network reset, taken SIM card out and fit back, tried SIM card in another phone to switch off still no joy. Spoken to Apple support who asked me to enter ##002# and ID mobile serever still cannot be seen and I get error message. I have been told that this is ID Mobile setting and they are the only ones who can reset it and thne stop call forwarding. I have proven the issue is not the phone but the ID SIM.
