Does your SIM work in the old handset still?

No just says emergency calls only but I had a message to say new sim activated bit not received one 

Odd, when upgrading you normally continue to use your existing SIM.

The fastest way to get this resolved @Leanne Langley would be to call in to a local Curry’s store and ask for a replacement SIM card. If you prefer, contact iD Mobile but be warned, you will be waiting a while for a replacement to be delivered via Royal Mail.

Thanks gonna go in currys tomorrow and get it sorted 

Hey @Leanne Langley,

If you’ve got the SIM Card now, you can head to https://www.idmobile.co.uk/help-and-advice/your-sim-card to activate this.
