    Everything was working fine untill a few days back when I suddenly lost VoLTE network on my SIM 1 and every time I make a call, I get a call failed error. LTE is working fine. I just cannot seem to make calls.
    This happened after I updated my phone to the latest security patch.
    I tried clearing cache partition, rebooting the phone etc. Nothing worked so far.

    Kindly help. I am not able to make to any calls

    Is the phone carrier-branded, or did you get it unlocked? If it's carrier-branded, are you using it on the original carrier's network, or a different one?

    It was already unlocked. And was working fine until the latest monthly update. . Could the update have caused the issue?

    It could be due to the update. Can you make calls if you turn off VoLTE, or does you carrier depend on VoLTE for calls?

    Depends on VoLTE for call. Cannot make any calls without it.

    Hard to say if there was a glitch during the update, or if the glitch is part of the update itself. I can't find an easy way to reinstall the firmware (it looks like Motorola Device Manager only allows you to update, not to reinstall the firmware). It's worth contacting Lenovo about your issue: https://mobilesupport.lenovo.com/us/en/contactus

    You could try a factory data reset.

    I believe I've had this issue.
    VoLTE allows a phone conversation and using data, simultaneously, correct?
    Most days, in the way home from work, I call the wife and have Waze running. Some, but not all days, Waze loses data and the LTE label, for the service icon is gone.
    If I cycle airplane mode, I can call back and have data, simultaneously. I do not know the cause.
    This is a US Unlocked Z2 Play with Verizon service.

    I'm on Verizon. The only time I've seen VoLTE displayed on the call screen was when in a conversation with another Verizon user on their VoLTE compatible phone.
    I don't think it crosses to let service providers.
    Please, someone correct me, if this is not accurate.
