You could use a call/SMS forwarding app on an old android phone. I haven't used any myself, but I know they're popular with small businesses.
Basically just get an old android phone, put a prepaid SIM in it, and leave it charging at home somewhere. The app will forward calls/texts to any other number(s) you choose.
