So overall I've been very happy with my launch day Gnex. No real issues to speak of. Verizon 4G has been good to me. But this afternoon, I made a call (checking voicemail), no problem. This evening, I went to make another call and I can't. It states dialing, but never connects. After maybe 30 sec, it states call ended. I tried calling my number, but it doesn't ring either. Now a Moto Droid 4 on Verizon in my other hand works fine, so it's not the network. I have full 4G access, and can connect with no problems to data. But I can't make or receive phone calls. So I'm not a noob at this, and did the normal Airplane mode toggle, then power off, then removed battery. Nothing. Forced 3G only, set roaming to home only, etc. Still nothing. 40 min with Verizon tech support got me nothing as well. Only options left were to factory reset and/or replace SIM card at store tomorrow. Anyone else have any gems of info on what to do here?
