My iPhone 6 calls have tons of static as soon as I leave my wifi assist calling area and the phone switches to regular calling (3G or LTE). Can't stop the static-y calls, even if I power down a few times, manually switch off wifi assist, turn off LTE. Nothing helps.
I'm frustrated. Any ideas of what to do? This just started yesterday after several weeks of using the wifi assist at home (which I have to have due to poor Verizon coverage in my neighborhood).
