I had this device for a year and it worked fine; about 3 weeks ago, it suddenly stopped working saying the error message above. I called Verizon customer service for assistance and did the factory reset, and did not work; now they sent me a new replacement and it is still poping the same error message, so it is not a device error.
Here are the setup message:
