Xfinity mobile as a back up

[Kevin-P]

Xfinity should be installing mobile SIM cards in all their WiFi routers so that when their system goes down, the landline at home switches to the mobile connection and still can make calls (and maybe limited internet). Power was off in CA the past few days and now that it is back, Comcast is still down so no landline for emergencies.
A home generator will keep the power on in the house during outage but doesn’t help if Comcast can’t keep their network running without generators (which they should have).
Comcast/Xfinity, your thoughts?

If there’s no power, like this one off you’re experiencing, what good would the Comcast equipment having a SIM card do. Never mind the fact there isn’t a spot for one.

How much are you willing to pay monthly for that hot-cellular-backup functionality you are requesting?    I prefer the zero-cost approach via which one manually retrieves cellphone from under-sofa-cushion when the power fails.
