I can't add my verified phone number on iMessage, it only says Add Another Email
I have added my phone number on my Apple ID, on my iCloud account on Contact Information.
And what I see on Send and Receive on Messages is "Add Another Email", I cannot add my phone number and I tried.
I have restarted my iPad, and logged off my Apple ID and then on; I guarantee I verified my phone number already.
iPad Air Wi-Fi + Cellular, iOS 9.3.5
