Apple hasn't ever included a Phone app on the iPad, and maybe that's just as well. Do we really need to see people with 7.9- or 9.7-inch devices propped up to their heads? Yet iPad owners may certainly need to make calls too, and like the giant conference phones of old, in some cases, bigger really can be better. So, if you absolutely, positively need to get your call on, and the iPad is what you want to use, you'll need to check out some alternatives. Luckily, there are several excellent voice calling apps to choose from, and one is even built-right in!
