How can you make calls with Samsung Galaxy Tab S3 with 4G/LTE? I am looking for a way to make calls from an Android tablet, namely Samsung Galaxy Tab S3 which has 4G/LTE support and thus has a SIM card slot. Do you know any ways of making calling from the Android tablet which are either official or not? 

I am open for rooting, installing custom ROMs and using external equipment like headphones.
From what I read, it can receive phone calls. So, I assume there's a Phone app?
