You'll need to call CS if you want to transfer your number to new sim card http://www.o2.co.uk/contactus

or how I lost my card and want to activate the number again I have to do it differently ?

Yes, you need to call CS as I said above http://www.o2.co.uk/contactus @Tomasz3

Did you report your sim as lost? They may have barred it. Not sure what action you have taken already. Either

way all the info you need has been given above @Tomasz3
