How can I stop scam calls on my iPhone?

Yes, that is what I have been doing the last months. Wonder if I should not bother to block the calls, but just delete them.

Blocking the calls is not what I suggested, even though Apple uses the word block in the title of the article. It is a different option than blocking individual numbers. If you do the following, it is not the same as blocking individual numbers and you don't need to block calls anymore. Here is my previous post again:

The option I use is Settings > Apps > Phone > Silence Unknown Callers.

The main mistake was answering and talking to someone. That only succeeded in confirming a live number. Your number will now be sold on various scammer lists of confirmed contact information, and the calls will increase.

Hey!

I hope you are doing well , and yes! I can understand your concerns on this and how irritating this can be.

Will be giving you the best option.

Go ahead and turn on "Silence Unknown Callers".

It isn't yet possible to block a range in iOS. But, there is a $2.99 item in the App Store that supposedly works very well for that.

There's also Simple Call Blocker, which is free.

I've thought of using the option, Silence Unknown Callers, but there's a big problem with that. There's a possibility someone you know is trying to make an emergency call to you from a hospital phone, police station phone or similar, rather than their cell phone. They would all end up going to voicemail. And who knows how long it may be before you notice you have voicemails waiting to be answered.

Put your phone on the Do Not Call registry. You can do it on their webpage. I have found that in the past this helps, but it is not always perfect, as unscrupulous scammer/vendors will ignore it.

I have found that by not answering, they usually give up. The iPhone is pretty good at usually identifying the calls as possible spam.
