Monday the network around 95 and deerfield beach boulevard was down due to a tower upgrade. This caused havoc for the business park i work in. lots of people with sprint couldn't make/receive calls or txts and the phones stayed in roaming. They fixed it by tuesday afternoon but it was definitely no joy. Got home tuesday and same thing happened in coral springs. I couldn't even roam. 4G signal went to crap afterwards and I can no longer get 4g in or around my home like before. I will say that i posted a question on FB and the person responding was a hell of a lot more helpful than there phone support. I was asked for cross streets etc and withing a few hours I got a response as to exactly what was going on both at home and work, near the home they detected erratic transmitter issues and opened a ticket for it, In deerfield they detected excessive blocks ? as well as they were upgrading the tower to LTE. Today I get to work and i actually get a decent 3g signal as well as in some spots I get 4g.. I think I will hit up sprints FB page in the future when having issues, they seem to get things done..
