How do i use iMessage on 2 iPhones?

Question

I have 2 iphone 6's (work and personal).  I want iMessages to be mirrored on both phones.  I have 1 apple ID on both and both phone numbers listed on both, so 2 phone numbers and 1 apple id on each.  I am not using forwarding.  It works great for a few days but eventually iMessage hangs up and i eventually have to shut down the phone and turn iMessage back on.  When is gets hung up, i can't even turn iMessage back on.  it seemed to work fine for a while, so not sure why it stopped.  anyone now the proper way to set this up?

Answer 1

i think the difference is i have both numbers checked, so both phones will get the same messages if either number gets a text or iMessage.  i suspect thats the conflict.  the phone doesn't lock-up, just iMessage does.  i was going t try the text message forwarding feature, but someone at an apple store said the text forwarding feature in iMessage is only for phones to forward to non-phone devices, but i may test that out to see if i get a different result.  this has worked ok for a few years and recently stopped working - wonder if it's iOS8.2....
