My iPhone won't send texts and I can't recive any texts unless I'm on Wi-Fi. My iPhone says I have LTE but nothing that requires internet will load. I have cellular data for all my apps turned on. I've tried rebooting my iPhone, and turning the cellular data off and on. My family members who are hooked up with the same data package can use their data just fine. Any advice on how to fix this?
