How to transfer my number from ee to ee

[KateA1]

I have been with EE since the 90's and kept the same number. THis is on my Iphone 12 mini. I also have an old iphone 6 plus which has a BT sim which is included in our BT package (i'd forgotten I had this phone). BT have now issued us with new EE sim Cards whhich I would use in my old iphone 6  but I want to have it in my iphone 12 with my old and cherishd phone number. How do I do this? Do I have to transfer the new number to my old BT sim and then transfer my EE (iphone 12 sim)  to the new EE or visa versa? I can't get my head around it and I can't get through to Customer support. I hope I've explained this correctly

@KateA1  You can not transfer contract numbers between SIM cards  ie swap them over.     You can however put the SIM cards in any device you choose.     If the BT one is a PAYG number you can move that over to your EE sim.  You will however loose the number on the EE sim when the BT number is ported over.    

Are they PAYG or contract numbers?
