Karina in Miami Lakes, Florida listens online and asked Into Tomorrow about using her tablet as a cellphone:
I have a new iPad Air that has its own cell phone number and cellular capabilities. Could this be used as a phone as well, to make or receive calls?
Unfortunately the iPad Air cannot be used as a phone to make or receive calls. It may have a number assigned to it for billing and tracking purposes, but it uses a dedicated data connection and not voice. However, you can use apps like Skype to make international calls at a low price.
There is one exception, you can make one kind of phone call without downloading any extra apps, you can make FaceTime Audio phone calls to anyone with an iPhone.
