How to find out if iPhone is unlocked if phone doesn't have a plan?

My phone doesn't have a plan so I can't check it by putting in another sim. Also, IMEI.info gave me an error message. The carrier in the "about" section in Setting says "Rogers 14.0". Any help would be greatly appreciated.

Call Apple. They have a way to check if it is unlocked. They will need the serial number of the phone to check though.
