What is the exact phone model? You listed two different models in your post.

You cannot add that device to a Verizon Wireless account
That is an old CDMA only flip phone. Verizon stop allowing those to be activated on their network as of July 1st as they are shutting down CDMA on Dec 31 2019.
It's important you have the right phone to meet your needs on your account, GYMSHU. You can activate a phone with the steps here, http://spr.ly/6584D22X0. To ensure the device is compatible with the Verizon network, check here, http://spr.ly/6585D22XF;
