Thank you this is very helpful. Can you please elaborate on "providing imessage is set up to use the phone number". I am now thinking this is the problem, as my texts to my husband come through on his phone as coming from my email address. ???
If you are using an iPad to send iMessages, your "Reply" address will be your e-mail address (as the iPad can't/doesn't have a phone number). The iPhone, on the other hand, can show the "reply" as being their phone number or an e-mail address (should they choose to have one).
If I remember correctly, when iMessage is turned on for the phone, it defaults to using the phone number and you have to add an e-mail address as extra if you wish. With the iPad, iMessage won't work without an e-mail address. Again, this is if the phone has been set up to use iMessage. You can, however, have the phone show an e-mail address as the "reply to" address. I do this so that any iMessage I send from the phone will be sent back to the e-mail address. This allows me to see the iMessage on my iPad also.
All that to say that what you are seeing is correct - a message from you and your iPad should show up on your husband's phone with an e-mail address to reply to.
Hope this clarifies.
