Hi there. I've been having dropped calls quite a bit. Verizon hasn't been helpful at all at trying to resolve this so far. Service outside the home is ok at 3 bars 4G. Even had Verizon drive by the front of the house to check for service availability. Had to buy an extender which I just set up yesterday after noticing numerous dropped calls from clients daily. (most of the time I just get voicemail notifications. No missed calls in my call log). Text messages won't send/receive either sporadically.
Wifi Calling drops too many calls as well as takes too long to connect sometimes, and call quality has alot of static sometimes over wifi. Right now I'm sitting next to the network extender which says service active 7/14 satellites connected, 0/16 devices connected. My Samsung Galaxy Note 9 is at full wifi signal, and 1x service.
Tried verifying the phone via #48, and says not connected (Welcome to Verizon Wireless, you are not 4G LTE Network Extender coverage. It connected yesterday when I installed the extender, and worked great for a few hours. I walked 10 ft away from it out of the room, and got disconnected from it. Now it no longer connects to it. Same with my wife's Iphone 10, and my mom's Kyocera flip phone.
