An iPhone 12 mini on my account has been having calling issues since day one. They have poor reception in the area they live (Raleigh, NC) so we tried wifi calling and we have a Verizon LTE Extender, that doesn't really work, it would still drop calls. People seemed to say this had to do with the iPhone 12's default band and that it would go to the "5G" band even in poor connection over choosing to connect to wifi calling or the LTE extender. I have no idea if that's true or not.
Then about a month ago they started running into this issue where the phone doesn't ring and doesn't alert them of missed calls. It rings twice and goes to voicemail for the caller. We have quadruple checked that do not disturb is not active. We have no idea what the issue is. The LTE Extender is still active but who knows if the phone defaults to that or not. Wifi Calling is usually active as well when this happens.
I've tried opening ports 500 and 4500 on the wifi network for the device but it doesn't make a difference. They have 200mbps down and 14mbps up with a wireless mesh network throughout the home.
Any help would be amazing, this has become a very serious problem as calls simply do not register.
Vanquished, we are terribly sorry to hear about the service experience you are having with one of your devices. We appreciate all of the steps you have taken so far in efforts to resolve this concern. Allow us the opportunity to further review. Can you please clarify if the service concern happens primarily indoors or everywhere you go? Also, can you please confirm that the device has the latest Software Update? Please go to the device Settings> General> About to locate the details.
This is primarily at home. It may be related to wifi calling or the LTE Extender that we got from Verizon. The dropped calls were happening before we got the LTE Extender and with or without wifi calling on but this no-ring/notify issue seems to be new since we got the LTE Extender.
Phone is running iOS 14.4.2
We have reset network settings a bunch of times and but it doesn't make a difference.
This appears to be a common problem with the Askey LTE Extender and Verizon has not provided a resolution. There are a few theads in this forum with this same issue.
Verizon - please provide a resolution for this.
Hi, Vanquished. Sorry to hear about the trouble. You've got a fairly unique situation there, because you've got some 5G signal coming in, but you also have an LTE Extender, and also have WiFi Calling active. The software in the phone is always going to try to connect to the highest priority signal, which is going to be the 5G signal. If the extender is in range, it will always connect to that next, and then only if the extender is out of range, should it be kicking down to WiFi Calling. However, whenever in WiFi Calling, if one of the other network types becomes available, it will switch again, and drop any current call. Whenever phones switch connection type, it can cause a period of "registration". This is basically the phone connecting back to the network and registering to receive calls. If you have very frequent signal switching, it's possible that this could cause a real problem for receiving calls. There's no way to lock 5G phones to LTE only, but you can try locking to WiFi Calling, which may completely alleviate all concerns. To do this, please ensure your WiFi Calling is active in your settings and then try entering airplane mode on the phone first. Then switch on the WiFi, and then wait a minute or so and see if the incoming calls work better. The one downside to this technique is you would need to remember to switch off your airplane mode when leaving home.
Thanks for following up. We send you a Private Note, please keep us posted.
Vanquished, we are concerned to hear you are having trouble with the ringer on your device. Is this something that recently began for you? Have you attempted any troubleshooting steps thus far?
Just to gain clarity, have you checked to ensure your Do Not Disturb is turned off? Have you tried to Factory Reset your device?
