Help Weird SMS issue

[Saheim]

Greetings all!

Not sure if I put this in the right section. Partly because I honestly do not know if it is an issue with my OS, Carrier, or Hardware.

I have a Note 5, my wife has a Note 3 (both on ATT). Neither device is rooted, both are running stock ROM and we are both (currently) using the native messaging app.

My wife's handset is actually Note 3 number FIVE. Her first one was damaged and EVERY insurance replacement up until the fourth one was defective.

Her original Note 3 was damaged but also developed a weird quirk - it would not receive texts from my mother's phone (all on the same ATT account). It received msg's from everyonelse, just not that particular number.

Fast forward to Note 3 number 5 - it has stopped receiving texts from MY number (Note 5 also on ATT). I will sit with both phones, send texts from one to the other. Texts make it from my wife's Note 3 to my Note 5 but will NOT make it from my Note 5 to her Note 3. I send texts to every other number, without issue.

I've checked in every setting I can think of and do not see any type of "block" on my number.

Ideas?

Thanks

I mean you could try using an application that uses Wifi/Data to text not the SMS connection. An application like this is listed below. Otherwise I would go back to AT&T and tell them of this issue.
