A:Answer Hi Chief,
Thank you for reaching out. I appreciate your concern regarding putting a SIM card and making phone calls on the Galaxy Tab A (2019). Unfortunately, the tablet doesn't include any SIM card slot and cannot make phone calls. However, you can still make one-to-one video calls via the DUO app.
Please see the user manual on Page 12, 13, and 73 for your reference:
