iPhone XR sim card
I have an iPhone 6 which I’m thinking of trading in for an iPhone XR because:
a) software updates are no longer available for the 6 and
b) I would like a bigger screen.
(I’m not really interested in a better camera which is why I’m not opting for an 11).
Can I simply transfer the SIM card from the 6 straight into the XR?
I’ve been told that they may not be compatible.
