What phone do you currently have?

This sounds embarrassing but I am using my Ipad Air like a phone. Yes you can use a large tablet as a phone as long as you put a sim card in it. I use earbuds so I can hear the voice of the person I am talking to. Tablets can also be used for sending SMS messages and texting is actually easier to do with a larger touch screen. My eyes cannot tolerate small screens, I am wearing glasses because I am a bit visually impaired. It is easier for me read messages when my screen is larger. I am actually planning to buy Ipad pro because it's screen is larger.
