I traded in my old phone and forgot to take out the SIM card! Help!! It’s iPhone 11.

there is no data stored on the sim card. IF you already activated your iphone 11 then you should be good, if not get a new sim from them.

Assuming that you moved that phone number to your new iPhone 14 via an eSIM …

… the old nanoSIM was deactivated by your carrier as part of the process.

Nothing to fret over.
