I can send text to everyone of my contact Just fine. There's only one specific person that when I send it, they receive it, but they send it to me and I don't ever get it in my inbox anymore. It just happened out of the blue. We can call each other too.
We've already deleted each other's contact and added it again. Restart our phones, checked for software updates, checked our blocked list in case we accidentally blocked each other.
Why would my friends texts not come through to me. He receives my texts fine.
