Thanks. Yes, all our landline handsets (currently) have to be plugged into a phone socket. I'm moderately deaf. My wife and I are both in our 70s in a large two-storey house. Two of the handsets are (expensive) amplified phones, and one of these is fitted with an (expensive) Oticon bluetooth device so I can hear it through my hearing aids. I use this one to make calls - or pick up calls once my wife has answered a call for me on one of the other handsets. (BT sold us mobile phones and SIM cards falsely assuring us we had a good mobile signal at home.) We are concerned that, once we have been moved over to Digital Voice (DV), in a power cut, we will have no means of communication. So Wifi Calling isn't a solution. We have yet to be moved over to DV but have had 'the letter'. I'm trying to work out options to avoid the situation in which, having been switched, we have only one handset or, in a power cut, none. I have considered battery back up but that seems to have a one hour life - it doesn't seem to say whether that is one hour of use, several hours if on standby or whether it powers the router or just the phone?
The best solution so far seems to be to connect the router to the socket system - disconnecting the faceplate from the incoming copper wires if I am able, and buying SIM cards from a network that gives us a mobile signal at home?
Alternatively I could buy 3 Adapters (to add to the free one) or 4 adapters (to add to the free handset). All our phone sockets have mains plugs adjacent. Hence my question: 'HOW MUCH DOES AN ADAPTER COST'? I guess BT aren't saying what the price is because they want customers to buy new handsets. This may no be a viable option for the deaf and retired. Please excuse the length. Thanks
