So my issue this time is when I am connected to Wi-Fi, with the phone, I cannot receive calls. I can receive text messages, which I guess makes sense, since those just wait until you have a proper signal and then send them. But phone calls I don't get at all. I have pretty good service I have at least 4g most of the time and it seems when I'm connected to Wi-Fi I can't get calls. If I turn off Wi-Fi and just go right to 4G, i receive calls with no issues. I am using T-Mobile in the United States and just wondering what I could possibly do to fix this. Thank you
