I live in Silicon Valley and am using a 5s. The phone's data speeds were blazing fast when I got it, now they're crawling. Symptoms: Slow data speeds, even basic things like refreshing email crawl on LTE (OK on wifi) Generally have only two bars of LTE. Occasionally I see up to 4 but it's rare. Data is largely unusable if I'm indoors - so slow that I end up needing to hop on a wifi network or just give up. Sometimes switching LTE off yields more bars, data speeds are still slow. Anyone seen anything like this or have suggestions? I'm used to having bad service in my house due to living in a VZW dead zone but it's weird that it's also soul-crushingly slow in other neighborhoods nearby. Most of my friends are ATT so don't have a great basis to compare to. Thanks!
