My husband and I both have iPhone SEs and we are each getting two of four bars which is completely normal for where we live. I just confirmed again that I can successfully call out (well not to hubby... again... his phone does the same as mine for incoming calls, it won’t ring and it eventually goes to voicemail)
I called support about this. There's nothing that can be done. Virgin Mobile ROMs rarely get updated... if ever, so bugs linger indefinitely. You get what you pay for. My ex pays for my service so I just deal with it. 3 way calling doesn't work either. Lol.
