Is there anyway to use a SIM card with a cordless home telephone?

I added another line to my ATT account to get an early upgrade while tweaking my plan so it virtually cost me nothing. Now I have an extra SIM card and mobile number and was wondering is there any technique or actual telephone that runs off a SIM card? I figured I could use the extra number as a home telephone but don't know what equipment would use it rather than a cell phone. Any ideas?
