Moving Data from Android to iPhone 6 plus

I am trying to set up the iPhone 6 Plus. I did start to before I tried to transfer the data from my Android phone.

I rest the iPhone but when I put in the code, the wifi bar on the iPhone disappears when I move to the move data from Android screen and the samsung cannot find the iPhone.

I just want to transfer my messages. I have successfully transferred info from my Android to Gcloud etc and email but I want to transfer the messages.

I did use a pig but nothing can read the file despite it saying Gmail and Google can read it.
