tower issues for sure. especially if its more than one phone.
I'm having dropped calls and It says I'm roaming even though I'm in the middle of the city. Also my text keep failing as well. My zip is 85206
are you able to get on the browser? it could be 2 things. either tower issues in your area. or your phone might have gotten stuck on a tower...or possibly mixed up some of its data as it was switching from towers. yes i know that was 3 things lol
easiest fix attempt is to pull your battery for a few minutes. put it back in. go into settings and update your profile and prl. see if that works. if not then call into sprint and have them check your area for tower issues. if nothing shows they have a way to kind of reset your phones reception. it makes it look for another tower from their side of things. also make sure your phone isnt set to sprint only. settings-wireless and networks-mobile networks-roaming. it should be on automatic
being stuck on roaming makes it sound like the towers more than anything though.
hopefully one of those things will help.
