Siegard, I tried what you said, but that didn't work. Finally I started from
scratch. I restored the phone and was unable, at first, to send and receive
text messages from my 5 s. When I went to settings, then send and receive, it
let me sellect two emails where I could receive i messages,
I would try and disable it first, then go to Settings > General > Reset and
select to Reset Network Settings. After the phone reboots, reconnect to your
WiFi, make sure you are on the same WiFi as your iPhone 6 and that you are
using the same Apple Id. Now go and enable forwarding messages
