so all of my reception issues on my 6s for the past 5 years has been caused by:
- literally it being so ancient it doesn't support 600mhz or 850mhz in my area
Which means that I've been only using 1900mhz ... so THATS why my coverage goes from -80 to -100 to -117 to NO SERVICE... and I've always seen anywhere from -110 to -127
