Residents of the Linda Mar neighborhood of Pacifica have been without AT&T cell phone service since last Friday.
AT&T says the problem is that the cell tower causing the outage is on top of a mountain and their heavy trucks cannot get up the muddy roads.
"We got rid of [our land line] a few years ago, thinking, 'Oh, it's not going to be a good deal,' and it hadn't been until now," AT&T Wireless customer Rebecca Newlin said.
"Unfortunately the tower is inaccessible because of the weather; it's up on a hill and the police are looking into that," AT&T store representative Cheyenne Santo said.
There are reports that someone deliberately cut the wires, but the AT&T spokesperson cannot confirm that. He also cannot confirm how many customers are affected or when service will be restored.
Thursday, the company plans to fly crews to the location to assess the situation.
