We have put together a short survey to capture your feedback in terms of what BT can do when you experience home Wi-Fi issues. We would appreciate it if you could take a couple of minutes to complete a short survey. Read more from here, Fix my home Wi-Fi
Yes, fair point. She does have a mobile but prefers the landline. My thinking was if she has to change eventually she might as well get a free phone but as you say, they are cheap enough.
Interesting that phones will no longer work in a power cut.
Digital Voice is delivered to the BT Smart Hub 2 over the Internet. If power is lost to the hub, then none of the phones will work. Any other equipment like alarms that rely on the phone connection, will also stop working.
Also, the free DV phones still need power to charge up the battery, so if they go flat, then they do not work.
BT do sell a suitable backup power supply for the home hub, but its not cheap, and other alternatives are available.
@tmarsh12345 if your Mum is vulnerable and moves to digital voice she would be entitled to a free battery backup unit to call the emergency services if needed. However, as you mentioned she has a Mobile so that could be used in the event of a power cut.
