If it was an upgrade, your old sim would still be working for you.

To use the new sim, you would need to do a sim swap Guide: Sim Swap: a mini guide 2017 update 

If it was a new contract, only O2 can help you and I can't understand why no one has, unless the phone is faulty.

If so, contact Samsung to check it out https://www.samsung.com/uk/support/contact/
