So i thought that if you upgraded your phone, you kept the sim you were currently using? I've been sent a new sim alongside my new phone so very confused as my old sim fits in my new phone etc.

When you upgrade, a new SIM is automatically sent out. Log into the iD Account and you should see a message asking if you’ve received the new SIM. Select Yes to activate this.
If you don’t see the message, go to https://www.idmobile.co.uk/help-and-advice/your-sim-card to activate your SIM.
