I have an iPhone 11 and I want to transfer it to an iPhone 14

If this is the US model iPhone 14, contact your carrier.

All US iPhone 14 models are eSIM only, so (here) transferring the cellular plan happens via your carrier.

If you're located elsewhere, swap the SIM over: Remove or switch the SIM card in your iPhone - Apple Support

Contact your cellular carrier to get your service moved over to the new phone.

Unfortunately you do not say what the new phone model is. Use these documents for guidance:

Learn which size SIM card your iPhone or iPad uses - Apple Support

Remove or switch the SIM card in your iPhone - Apple Support

If you cannot move the SIM card, contact your telephone carrier for help.
