I’m helping a friend set up his Galaxy S23, purchased in the US. We now live in Portugal. He has a Portuguese SIM (from MEO) and a US SIM (from Tello). We just configured the Tello SIM. We need to make sure Wi-Fi calling is enabled for his US SIM. I’m an iPhone user, so I’m used to that process, where each SIM has its own configuration screen.
How can he make sure Wi-Fi calling is enabled for his US SIM?
Thanks!
