Hi Maria17,
Thanks for posting on our community forums. Great news that you have decided to join us on a sim only deal, but apologies that we have added two sims to your account and not one.
This will not be an issue to remove one of these for you as you only require one sim deal, but for me to do this I will need to pop you over a private message to take some details and see what mobile number you wish to keep.
Please click on the purple envelope to accept the chat.
Kind regards Jodi,
