    Hello there.

    I'm encountering a very inconvenient but consistent problem. I recently bought a Blackview 9800 Pro and it's working very decent, but whenever I'm at my desk at work, I'm not able to make or receive phone calls. I'm able to send and receive text messages and my mobile data (4G) is working, but phone calls aren't possible.
    When I'm somewhere else everything is working just fine.

    Is there maybe a setting that enables location based call restrictions?
    Does someone have an explanation for this?

    I work at a small engineering office of which the I.T. department is basicly me. So I'm pretty sure there are no jammers installed or something. Would be strange to, because I need to make phone calls for my work now and then.

    There are some spots that have no signal, and it could simply be that.

    Welcome to Android Central! How many cell signal bars do you have at work? Are you connected to wi-fi and using wi-fi calling?

    I have full reception. With my previous phone, there wasn't any problem.
    Yesterday I think I've found the problem. We have a mobile signal extender in the office, close to my desk. When unplugged, my phone works normal. So ironically enough, the mobile extender jams the signal of my phone.

    Aha! Good detective work. In my experience, network extenders do tend to cause glitchy behavior.
