I searched the forums for another thread on this topic, and apologize if this is brought up somewhere else. I added my phone number to iMessage on my iPhone and have it configured on my Macbook and iPad as well. Works great at sending as the phone number and works great receiving as well. So, iMessage is having some trouble with activations, as discussed in a few other threads. This caused iMessage for some reason to become disabled on my phone. This sets up what I feel is a design flaw. I was hanging with a friend and showed up to his house but he wasn't there, so I text'd him (he has an iPhone as well) to find out where he was. No reply. Eventually I called him and we met up. During the day I text'd my wife and never heard back from her. Eventually I called her and she said she had text'd me back. I looked in the settings and realized iMessage was disabled (turned off). I knew that I would get home and those messages would be on my iPad. Low and behold, they were. Summary: If you add your phone number to iMessage but your phone is out of service (not yet verified, but assumed - tried with Airplane Mode on, send message, airplane mode off, and it never came through) or iMessage for some reason turns off, you will not get your text messages that are sent from other iPhones running 5.x and above. Anyone else have experience with this? As much as I love being able to send text messages as my phone number from the Macbook and iPad, I need to make sure people who text my phone get through to my phone.
