Phones just don't work anymore in rural areas.
My landline's been dead for over a week with some trouble at the exchange. Using the mobile phone I usually keep in the car for emergencies I tried calling someone who lives locally yesterday, outside for good reception. It went to voice mail on two attempts. A while later they called back and said their phone hadn't got reception where it was in their house when I'd called. I went outside to get better reception on my end, but then it was too windy so they couldn't hear me, so I went into the shed but the phone dropped out, so I went out again and yelled into the phone, and I still don't think they could hear me. I gave up.
Both of us were within line-of-sight of the phone tower. Phones say they have signal inside the house/shed, but since the 3G switch-off it just doesn't work anymore (although my older 4G mobile broadband modem somehow seems to work a little better). But they're in no hurry to fix the landlines because everyone's supposed to be using mobile phones!
