I have read the other posts about calls going straight to Voice mail and I am having the same issue. My bluetooth is not on.
It has happened twice
and each time I've had to call Verizon. There's no indication on the phone that this is happening: I've got cell phone bars, I can get on Facebook, etc., but when people call the phone doesn't ring on my or their end and goes right to VM. The Voice mail alert doesn't come in and text messages don't come in either. The only way I'll know is when someone tells me or if I call my cell from another phone.
The second time it happened. I called Verizon and tech support said that my phone wasn't registering on the network, so it thinks the phone is shut off, even though my phone wasn't powered off. I had to go through the steps of dialing *228 and re-registering it on the network and finally all of my texts messages that I missed came in and they called me on my cell and it was working again.
If it happens again, then I have to call Verizon back and do a factory reset.
To those that are experiencing this, I'm wondering if it's because I let the phone's battery discharge completely, so that it shuts itself off, before I recharge it. Maybe that could be doing it?
If you have solved the problem please let me know how you did it?
