My iphone is locked and saying " sim Invalid"

Brought a tescos sim card for my iphone and it says 'sim card not valid' but when I filled in the activation codes online I did not put in my iphones number, I put in a different number, will it not work?

Check your sim card in another mobile . . .
80% it will not work
but if I worked , put out your sim card from your iphone , then connect your iphone to Itunes , then out sim card back .
i don't have any more idea . . .
