mdav056:I'm not sure this is right. I think most tablets with a sim are set up for data only.
As I mentioned earlier, it depends on whether the manufacturer cripples them to as not to compete with their other product lines. I've got an ancient Cube tablet (Chinese brand, slightly better than noname) and that does phonecalls. Here's the first hit than came up, that's a more expensive dual boot one and several years newer than my one, but does calls just as well. Just google phone call tablet or something, there any huge numbers of second- and third-tier vendors who don't cripple their products.
