Yesterday i tried with a friend to solve that.
I changed my send/receive configurations... i choosed to send/receive by my two emails and my phone number and start a conversation with the email of my Apple account.
Then, my friend received my message on her email and one of her iphones numbers. But one of them remaining "not delivered".
Today, i tried to repeat this again and test and i can´t send again any imessage.
I think i will go to an Apple Store to ask about how can it be possible.
