There is a tower out in Irving that is out..or a sector on the tower.
Engineers are trying get to the tower to look at it, but its on private property and they are trying to get a hold of the owner of it.
You can call sprint customer service, ask them to log you a trouble ticket with the trouble ticket team, as there is a known sector outage on a tower in Irving. It started dropping calls/service on 7/25.
BTW...if you can get service away from your house, your phone has a call forwarding feature. dial star then 72, put in the full # with area code, it should give you 1 to 2 beeps, this will forward your calls. dial star 720 takes it off. so star 72 972 123 4567 beep beep and it will go to the phone you directed it to.
