Broken phone

[JLB1980]

Morning EE

my screen on my iPhone 12 is smashed and the LED has also gone making it completely unreadable. 
while I look into options of getting this fixed how do I re-use my old phone that I originally upgraded from. It’s no longer as simple as “take out your SIM card and reinsert”

Hello @JLB1980 ,

Welcome to the community,

Why is it no longer simple to take the SIM card out of one phone and insert it in your old phone?

If you are unable to do so, you will either have to request a replacement SIM card or go to a high street store with ID and request a replacement SIM card. If you have esim, then you would have to request a physical SIM card.
