As noted by Droid Life, there’s a bug on the Verizon version of the Moto G5 Plus: it can’t dial 911 if you’ve turned on Voice over LTE (VoLTE). Lenovo has acknowledged the problem in its forums and says a fix is on the way soon:

We will be issuing a fix for this issue within the next week. Please accept and install the software update as soon as it is offered on your device.

The issue was uncovered after a G5 Plus user was unable to call emergency services and posted about the issue (and the less-than-adequate initial responses from Lenovo) on Reddit.

In the meanwhile, Lenovo recommends digging into your settings and disabling “Enhanced LTE Mode,” its name for VoLTE. Doing so will ensure that you can dial 911, but it will also mean that you won’t be able to use both voice and data at the same time when you’re out of Wi-Fi range. Small price to pay, especially if Lenovo and Verizon make good on the promised fix next week.
