I just migrated from pay as you go to contract.  Suddenly my phone stopped connecting to the network (it connected perfectly as pay as you go).  Thought it was a sim problem and tried to lock and unlock my sim card.  Now I am told the sim card is disabled and for me to enter the PUK code that I must have thrown away.  What should I do?

@AMEODE 

You can get your PUK here https://www.o2.co.uk/help/phones-sims-and-devices/unblock-your-phone?osr=puk 

Edited to add, you need a new sim card when moving to contract as they are different.

O2 should automatically send you a new sim card when you arranged to go onto contract

If you haven't received it you need to call them

Contact numbers from any phone or Skype here Guide: Coronavirus Community Help and Support 

When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
