How can I block calls that do not show a phone number?
An interesting question, which I’m going to answer initially with questions of my own. Do the calls in question show up as “private caller” or something similar? Which Republic phone (brand, model and if applicable generation) do you have?
I have a Nexus 6p with Oreo cookie on it and yes they do show up as private or just showed up blank they’re always advertisements I even get texts in the same way it’s quite annoying you can’t call him back you can’t get them to quit calling you and it’s really a pain at the worst times
At the Nexus 6p by Huawei
Not all phone models have an option to block private callers.
