I have a Galaxy Note 5, and a short while ago, I had an issue where I would send a text, but the recipient would not receive it. My phone would give me a sent text notification but the receiver would never get it. I thought the issue had been because I switched from Apple to Droid, so I removed anything with my phone number from my apple account, and also texted STOP to a number suggested by Apple, and it seemed to fix the issue. Now, I just updated Messages when the update rolled out, and I cannot send messages again to the same person! They are getting NONE of my texts. I have uninstalled the updates and restarted my phone and still nothing works! They have an iPhone, but I can text to other iPhone contacts no problem. I need a real solution to please. I have full bars, am connected to WiFi but this won't work!
