Cant make calls but can send texts, Samsung A20s

I have a new Samsung. It is unlocked. I inserted my SIM from the last phone. I downloaded and updated the software. But now I can't make calls, only texts.

Presuming your unlocked phone is on ATT’s list of supported phones, you may need a new SIM card. Depending on how old it is, it might not support ATT’s VoLTE, which is required to call. The first thing to try is get a replacement SIM card.
