Iphone 6 required Remote management when set up new iphone

It is clearly not a retail new iPhone 6. It was a company phone and is tied to the company that owns it. Either the seller was selling stolen property, or if they did have permission to sell it, they did not take it to the company IT people and get it released for re-sale.

Since the iPhone 6 was discontinued more than a year ago now, it’s questionable anyone would have truly “new” devices sitting in stock. The only truly new iPhone 6 model available is the 32GB model that has been re-released through some officially supported carrier stores (those re-releases are supposedly being assembled from unused stock parts and Apple itself does not sell them).

You cannot continue to use it unless you can login to the company profile. I don’t care how big or how reputable the store you bought it form is, that is NOT a retail new iPhone 6.

Farmers Group Inc. is an American Insurance company. If their company profile is on that phone then it was originally purchased by Farmers and set up under their corporate IT deployment policy. Unless you are an employee of Farmers Group Inc. you cannot use that phone.

You were ripped off by the store that sold it to you, and should take it back and demand a refund. They or whomever the got the phone from must have hacked it to bypass the company profile and make it work, and now you’ve restored it, the hack has been removed

Where, exactly, did you buy this "new" iPhone 6? Sounds to me like it's stolen and was repackaged to appear new. Re-packaging a phone is trivially easy.

Take it back to wherever you got it.
