Many of the calls are actually in Mandarin, which I don’t speak.
Over the last few months I’ve seen my spam phone calls go from around one a week to like ten a day, and it’s been infuriating.
After a good bit of Googling, I ended up coming up with two solutions that reduced the problem by around 90%.
A lot of spammers ignore the Do Not Call List, but many do honor it. It’s not possible to really know the ratio there, but being on the list will definitely reduce the number of calls you get to some degree.
This one is obviously AT&T only, but there are similar apps for other carriers below.
AT&T Call Protect is a carrier-provided app that automatically filters spam and fraud calls, and has a mobile app to help you manage it and see what it’s blocked.
Nomorobo is a third-party app that I settled on after trying 3-4 alternatives. I actually liked the look and feel of some of the others much better, but this one seemed most effective at stopping calls when combined with AT&T’s offering.
For non-AT&T customers
This is a cat and mouse game, and the spammers are always adjusting, but this has helped me massively and it should work for you as well.
