As you have just activated then this takes a little while and can be upto 24 hours to complete however it can be sooner, so please wait a little longer and you will soon be up and running….please do insert the sim into your phone and restart your phone every hour or so… don’t worry this is the normal procedure. A confirmation email will be sent to you.
You'll then see the "Congratulations. You made it!" screen to confirm it. You'll then be invited to use the Setup Wizard. This last step is very important as it is used to make sure your phone settings are correct, so you'll be able to use Internet and MMS.
