Help me remember what movie this is.

[Cidien]

It's a horror ghost movie. They're somehow using electrical devices like TV's and cell phones to exist. At the end they drive away into dead zones to escape but find a pocket with radio transmissions and they get in through the car radio. For whatever reason red tape keeps them out. At one point they find someone partly responsible for what happened with his room completely covered in red tape.

Just can't seem to remember what this movie is called for some reason. ><
