Hi everyone. I hope someone can help me. I have an iPhone and iPad both with the most updated operating systems. I can text on both to my niece and sister's iphones/ipads without any problem. iMessage works amazingly well and I am able to use their phone numbers.
But, when I message my friend who has the same setup as me, I can only send to her number from my iPad and not receive her messages on my iPad. They only come to my phone. And, she has the same problem. She can send to my number from her iPad but can't receive from me.
So...I believe the problem is on her end. I had her completely power off everything, toggle the iMessage on/off switch, match up her AppleID in the receive at section, etc.
