Stop the closure of the Public Switched Telephone Network

The PSTN works with a simple corded phone into a landline, & continues to work even when a powercut occurs. Digital broadband & Voice over Internet Protocol services are often disrupted. During a powercut, with mobile reception poor due to severe weather conditions, the PSTN can still work fine, providing a communication option for elderly and vulnerable people to stay in contact with friends and family. Digital systems often won't work, and mobiles can be out of credit/charge.
