After repeated data breaches that no company really seems to give a s— about my phone is blowing up with literally hundreds of spam calls and texts month. I get and make MAAAAYBE 2 or 3 important calls per month, 180-200 of the rest are literally all spam. Anyone have any suggestions, apps ect that they have found refuge with? I really don’t use SMS that much either, mostly it’s via signal, discord whats app, ect…

Just to put it out there I run CalyxOS on a Pixel 5a.

  • Note: this depends a lot on which governments you pay taxes to (country, state/province, city). With that in mind:

    • Check if there’s a “do not call” list where you live - i.e. a gov-enforced list of numbers that you are forbidden to call for advertisement. If there is one, put your number there.
    • Do not answer spam calls at all. Usually it’s easy to identify them, but there are some applications for this, like this (it’s in F-Droid so likely available for CalyxOS). By simply not answering those calls, your number gets marked as “inactive” by the advertisers/spammers/telemarketers, so the frequency of the calls gets lower over time.
    • Get a new phone number, redirect all legitimate contacts to your new number, and trash away the old one.
    • gov-enforced list of numbers that you are forbidden to call for advertisement. If there is one, put your number there.

      As a scam caller from some country the US has no influence over, that would be a great resource!

      • I believe that it should still reduce the likelihood of spam calls - because you don’t advertise where you aren’t selling stuff, and if you’re selling stuff you don’t want to piss off the local government.

        For reference: where I live the “do not call” list is from the state. Most of those spam calls come from people in other states controlled by the same republic, thus not subjected to the rules of my state - and yet the “do not call” list still does its job.

  • I had a similar attack of spam calls for a while. It started the moment I answered one call and continued for months. Simply not answering was not enough. Blocking specific numbers does not help either because they change every time. I then blocked all calls not in my address book for a few weeks and that helped. I could then disable the block again and for a year only got an occasional call here and there but could ignore it based on the area code. Now it finally seems quiet.

    I’m on an iPhone. Could not find any other way that would help me block spam calls that is not expensive and/or privacy invasive. So blocking everything is the only option.

    • The federal Do Not Call list is effective at weeding out legitimate companies trying to sell products that should be illegal, but scammers obviously have no need to respect the Do Not Call list. Unfortunately this is a problem with many sides, including captive regulators, insane wealth disparities between nations, cultural conflict, and problematic network protocols, so it will require action from multiple angles to fully stamp out

  • I kept my phone number from a different state so everyone that calls from that area code can be ignored. I also have AT&T’s ActiveArmor app (free) and it blocks most of them. I used to get 2-4 a day but I’m down to 1ish a week now.

    Answering vs not answering didn’t really ever make a difference for me, but I’ve heard lots of things like don’t answer and they’ll think the line isn’t real or answer but play the do Do DO sound effect or answer but leave it silent. Not sure if any will help.

  • Is there any pattern to the numbers they are coming from? For example, many of the calls i get spoof my area code and first 3 digits so I block those numbers automatically.

    I’ve also used an app called Mr. Number in the past to screen potential spam calls for me.

    Port Phone number to twilio

    Set up call rules for incoming messages. Drop off calls from the same area code three digits as your number.

    Then forward to your phone

    You can do the same for SMS.

    I want one step further, and got a new number in Montana, the least dense state. And I know if any messages or calls come in from a Montana number it’s purely spam, so I drop those calls.

    You can go a couple steps further, get a bunch of twilio numbers, and give them out to different businesses when they require a phone number. Then if you ever drop the relationship with that business, you can drop the number and if the number leaks you know where it came from.

  • I know they don’t have the best reputation, but Truecaller’s ‘Voice Assistant’ feature has been a godsend for me. The basic bot answers calls from unknown numbers and transcribes their response before ringing, and only if they don’t hang up. I’ll look at my phone to see I have a few missed calls from unknown numbers, only to find that Truecaller intercepted them all and they hung up once they heard the message that the call was being screened. It’s great.

    Folks that call for legitimate reasons that aren’t in my contacts generally leave a message and I get the call once they’ve left it. Folks that are in my contacts ring as normal.

  • I run ‘Should I Answer?’ as my dialer. Imperfect, but phone rings ~80% less. Sms, I stopped trying after T-mobile intermittently stopped delivering me texts and declared they’ll only support Google’s official messenger.

    FCC, & everyone else responsible for this garbage oughta sit on spits.
