I have inherited my father’s iPhone. It has no SIM card. I don’t know his 4 digit passcode. Am I able to make use of this iPhone if I get a SIM card for it ?

I don’t know his 4 digit passcode.


What model iPhone?


If it is old enough to have a 4-digit passcode, you may never be able to activate it. Apple's changes to iCloud system requirements in Nov 2025 mean that an iPhone must be able to run iOS 11 or higher to use iCloud Services. Many reports here suggest that also means that iOS 11 is required for activation.


The following iPhone models cannot run iOS 11:


— Original iPhone

— iPhone 3 (all variants)

— iPhone 4 (all variants)

— iPhone 5 (all variants EXCEPT iPhone 5s)

If he let you know his apple ID and password fhere is no need to go the legal route. Simply reset it in recovery mode using his comouter.

If not then sberman gives the only way.

My family know my passwords for when I go, and my 4 digit password which has always been an option and still is. Apart from anything my account holds 65 years of family photos.
