This app was horrible!!! I tried it the first time WITH a verizon rep on the phone providing direction. We finally got it to start the transfer process but it was so very very slow transferring I went out the app and the procesd STOPPED. Had to start the entire process over!! The 2nd attempt took just as long. So many quirks with the phones not being recognized with using the wifi. One phone would be ready for the four digit code however the numbers wouldn't be accepted on the other phone.
