iPhone not activated
Can I activate my iPhone without knowing iCloud password
iPhone 11 Pro Max, iOS 16
Question marked as
It depends upon what you mean by "activate". Usually "activate" is understood to mean setting up cellular service. That is separate from turning on and using Apple's iCloud services which do require you login with an iCloud account.
