The grandkids don’t have a phone yet, but I dropped the landline years ago. I never answer a call unless I see the name. My blocked callers list is huge!
******************************************************
Been blocking calls for years. No idea how long it is.
Use an app called ‘knowncalls’. It’s a whitelist that uses your contact list, no external data required. If the number isn’t in your contacts list it gets blocked.
Put it in both phones - got tired of hearing the complaints from wifey-dear.
Started blocking calls on my Spectrum landline which never worked. Chose to turn the ringer off so I wasn't bothered. Finally got rid of the landline and cable a couple of years ago, so the only service I have with Spectrum is internet.
When I got my first cell phone, it wasn't a smart phone, just a plain 3G phone.
When I was forced to get a 4G phone, I bought an iPhone because I've always used Macs. This is only my second iPhone and I use Verizon's call filter. The phone is set to only ring when someone in my contact list calls. All other calls are silenced. Many are completely blocked as they are suspected spam. Other calls are silenced, and if they show up in my recent calls, and I don't recognize them, I block, hit delete, and also report them as junk.
Same thing with texts I receive that are clearly junk, hit delete and report them as junk. Last year, the political texts were ridiculous. I deleted and reported all of them as junk. Thankfully they stopped after the election.
Recently, I've gotten two or three texts from someone claiming to be associated with EZ Pass, NY State's thruway toll system. I have an account and know how much money I have in it. The texts are telling me I owe money. Last one provided a link, which of course I didn't click on. The number they called from had a country code of 63, which is the Philippines. All were deleted and reported as junk.
On iphone phone app, you can turn on "Silence Unknown Callers" This sends callers not in Contacts to voicemail.
