Is there a way within Verizon to block all numbers from a country? i.e. by blocking every call with a specific prefix(es). There are several apps which do a version of this, but I would prefer to limit providing phone access to third parties.
Blocking individual numbers does not help, as these are robo-calls being routed through numerous numbers in the same countries/exchanges.
As consumers ourselves, we can understand the nuisance that these spam calls coming from a specific country can create. We have different tools that allow you to block these numbers for free or advanced features that will allow recognizing these numbers when they call you and block them from calling you and texting you. Please review the options we have to offer in the link below:
From your link, it appears the only viable option is the $3/month Call Filter. However, I have seen reviews that this service only flags calls and doesn't effectively block them? And is it able to stop spoofed robo-calls?
We totally understand how important it is to avoid unwanted calls, especially when they are from another country. We do want to help review what options are currently available to you.
At this time there is no way to block international calls at all with the tool we have available. However, there are third party apps that can help direct international calls to voicemail when they are received. Another option is to change your mobile number. This is something that many consumers do, since their number is known by those third parties, that is why they are getting those unwanted calls https://www.verizonwireless.com/support/change-mobile-number-faqs/?lid=sayt&sayt=mobile%20number%20c...
We are also developing new tools for our customers to combat spam and spoofed calls as well. You can always check back in the future to see what options may be available in the future.
