This made me curious so i poked around; their github issues has one where they state the sim module sim7000g doesn't support voice calling. The datasheet does list VoLTE, but its asterisked with a note saying "in planning"

I think the T-Call can do voice calls, but it’s only 2G if I understand their documentation correctly. https://lilygo.cc/en-pl/products/t-call-v1-4?variant=4344064...
