Sprint, along with three other entities happen to rule the mobile industry and done so for quite a bit of time now. Sprint has always prided itself on coverage and towers. Well the reality is the tower systems lack depth so your coverage sucks. Personally ive lost signal and still was lost data evening though im in a state of roaming or airplane pretty much.
I find the phones more reliable then the service. Rude customer service reps. And idiots over them. They love to contact you though for there money. Why pay for baby networks? You worth a billion. You guys seriously need to step up.
