Since about May of this year I have not gotten more than two bars (LTE) no matter where I am. Took a trip to upstate NY where my phone was pretty much useless for days & I NEEDED my maps. Hotspot has not worked consistently which has affected my business and now my mail and all apps seem to be lagging. I've reset networks & phone. Pay a lot of money to have unlimited data but it's worthless if it doesn't work!
