Unauthorized/unauthenticated msg when trying to d/l backup assistant

We bought new Verizon labelled 8560s off eBay to replace our old 8560s.

We were able to activate them online using the MEID. However we could not finish the programming (we're in a rural area) and had to call Verizon customer service for assistance.

They walked us through the manual programming and the phones worked fine for voice/text, but we could not download the Backup Assistant to restore our contacts. The message was something about lack of authorization/authentication. Called Verizon again and their suggestion was to go to a location with Verizon service, which we did, but continued to get the message.

Went to a Verizon store with the phones and they tried a few things, including a reset to factory defaults and reprogram, but continued to get the message.

Called Verizon and they have no clue as to why this is happening. The tech connected a phone to our number and tried there to d/l Backup Assistant and had no problem.

We will return the phones (the eBay seller is responsive and we'll get a full refund) but we'd really like to keep them so we're looking for help here. We noticed that the phone info for the new phones had S/W version VX85607, PRL 52642 while the old phones were at VX85605 and 51143. All other versions (Media Center, browser, etc.) were identical.

Does anyone know if this might have a bearing on our problem, or have a clue as to how to solve our problem?

TIA

That's strange. The first thing that comes to mind is was the number in the phone changed to your current number. If I remember correctly this setting is separate from the programming and I'm thinking it may affect backup assistant. I'm assuming when you first programmed the phones and tried to use backup assistant the correct credentials were entered, or did it not even get to that point?

The phone numbers had been ported over to the new phones and were visible under [my number] in the [phone info] menu. We were able to call each other using the phones.

Activation is a 2 step process: (1) online you enter the MEID to activate the phone; (2) dial *228 to finish programming, or, as we had to do, call Verizon to do this manually, which may be due to our rural location.

Thanks for the response, and for helping think this through.

You need to change your simcard.Sometime these issue are mostly comes with sim card.
