Calls are being made for mobile phone provider EE to do "whatever is necessary" to restore the signal to Dentdale.
The area's been without phone signal for two weeks following problems with the mast.
Several local residents have complained about it - and there's also concern that it could jeopardise residents’ safety, as the local First Responder team relies on the use of mobile phones to communicate.
For much of the area, EE is the only mobile phone provider.
Local MP Tim Farron has written to the Chief Executive of EE, asking that they “deploy all available staff to locate and repair whatever is causing the breakdown as a matter of the most immediate priority”.
He said: “In the 21st century, mobile phone signal is not a luxury, it is a necessity. Local residents and businesses alike are reliant on mobile phones every day. More importantly, the First Responder team also rely on mobile signal. Every day that this mast remains broken is another day of risk for local people needing to use that service.
“It is simply not acceptable for the phone signal to be down for two weeks, and for EE not to have fixed the mast. They are showing a complacent and disdainful attitude towards local residents who rely on the signal from the EE mast.”
