    Most likely your phone previously was carrier unlocked using an unauthorized method.  When you updated, it was re-locked to the origninal carrier.

    Where did you purchase the phone? 

     

    There's no reliable way for you to determine the carrier it's locked to.  Apple may be able to do this if you call them

    "Apple dealer" - do you mean a corporate Apple store?  Apple doesn't unlock phones.  They can sell already unlocked phones from the factory.

     

    There are no settings in the phone to unlock.  Downgrading isn't supported and wouldn't help even if you could.
