@bejcass Good afternoon and welcome to 3Community, we're delighted to have you 😁 To answer your question, it sure is possible to move to SIM Only and keep your current number. To do this, log in to your My3 account and on your dashboard, you'll see the option to move from Prepay to Bill Pay, in here click Check Bill Pay Offers and you'll be brought to our online shop. Here, the first option you'll see in the item list is Bring Your Own Device. Select this to choose your SIM Only plan and continue through the order process. Let me know how you get on 👌
