Hi, I'm in desperate need of access to Wi-Fi calling on my S7 Edge (running Nougat, and thru Sprint) which I've seen 1000x and never understood so just ignored. Now i need it and followed the process that i thought wud lead me to it but it's no longer there (settings>Wi-Fi>advanced>shud be here!!!). Idk if something changed with this or if I'm just in the wrong place. I've googled it and followed the paths that were posted to access it but to no avail. It's really really important! Can anyone PLEASE help me?! I'm in panic mode! Thank you!!!!
