I recently picked my wife up an HTC One V from Virgin Mobile. She's upgrading from an LG Optimus V. Adjusting to ICS has been different for her. She's noticed that she's only receiving around a 3rd of her voice calls. We have excellent coverage, so that doesn't seem to be the issue. Voicemail will suddenly appear in a zone where she has full bar 3G service. I tried calling her phone from my Triumph, and she received the first call, but the second two didn't register on her phone. Is there an ICS specific setting that could be causing this? Thanks for any input.
