I switched to Verizon last year, I have been faced same issue that people call me straightly to VM. I called customer service and technical support couple times which still haven't solved until now. every time I need to restart my phone then the phones back to normal. after few days. it happened again. same as my wife's phone. happened once awhile. Couldn't fixed issues even I reset the network, reset phone. Also, I switched new phone 12 still happening same issue. My old and new phone were using E-sim, not sure it is because e-sim issues or not.
