Ok, so I tried to do this tutorial to fix the SMS bug that was keeping me from texting my buddy in Switzerland (I'm in the US using AT&T on a Samsung Galaxy s6 Edge with Lollipop v5.0.2);
I followed it, did the
*#*#4636#*#* and brought up the screen. Hit "Refresh" and it displays
So I hit update "Update" and reboot. Now not only does my texts to him fail, but all the local US people I can normally msg fine fails as well. Could someone show me the light? Thanks!
