No incoming calls, my friends who call me just hear a busy signal, but my R+ phone never rings
Throughout the morning and afternoon today, I have not been able to receive incoming calls. Different friends call me, but my phone never rings. My friends just hear a busy signal. My friends have called from both land lines and cell phones, and they all get the busy signal. They have called a total of 25 times to test. They have called from different carriers including AT&T, H2O, and Cricket. I am in Los Angeles. I can call out, but incoming calls are just non-existent, no rings at all. This is a RingPlus-specific problem because my other phone on standard Sprint receives phone calls just fine. I have read others mention this problem before in Discourse, Howard Forums, and Slickdeals, so I hope R+ finds a permanent fix for this problem. Thank you!
