WiFi service while keeping landline
I’ve had Sonic for home internet service (DSL) for many years and been very happy with them.
As of July this year Sonic is changing to fiber optics which is faster- yay! - but it means I will loose my landline. I don’t want to loose my landline since the phone still works in a power outage and my 86 year old mother will only call me on my landline number.
Any suggestions for WiFi only service not bundled that will allow me to keep my old fashioned landline? Are landlines doomed?
