I was wonder if you sell laptop computers that have a SIM card port?

You asked the community, not best buy. Call them. But I'm sure they do

I work with the Geek Squad. Cellular enabled laptops are not super common and I don't think we STOCK any in the store, but you can order them online.

Though depending on your desired use, you may be better off buying a tablet with 4G/5G capability, like a Surface or an iPad.
