Hi @Seby Fernandes,
Thank you for your message.
If you'd like to upgrade to a SIM Only deal, you'll need to log in to your existing iD Mobile account through the iD Mobile app or website and view the upgrade options available to you. This ensures you keep your current phone number and avoids accidentally creating a duplicate account or line.
Alternatively, you can contact our Sales Team on 0800 049 0250 or via Live Chat at https://www.idmobile.co.uk/live-chat, and they'll be happy to discuss the available SIM Only deals and help you with the upgrade.
Thanks,
