Since getting this prepaid Verizon plan a couple of years ago, my phone will randomly stop accepting calls. It won't ring, it will just send callers straight to my phonemail. It also will not alert me that I have any phonemail messages. This happens all the time, constantly. I have no warning. It is extremely upsetting to my elderly parents if they cannot reach me for a day, or two days, because my phone decides to turn into a brick, and I don't know it. It WILL still access the internet, email, etc - which makes it almost worse, because I think it is working fine. Restarting it will fix the problem, but I cannot keep restarting my phone every hour, on the hour, so that it keeps working. It does seem to happen when Verizon sends its monthly "thanks for your automatic payment" message, and it seems to also coincide with changes in my phone's display (meaning Verizon pushed some sort of update through, I assume). Something needs to be done. This situation is unacceptable.
