Can I use my number both on a physical sim and a esim at the same time

A nice idea @Jalexa94 .  Unfortunately,  this won't work, when you move to eSim, the physical SIM will be disconnected.

Any given mobile number can only have one active SIM at a given time. This is a technical restriction that applies to all UK mobile networks
