There are a lot of spam calls, so how can I block them?

A. 1

There are a lot of spam calls starting with 070.
If it starts with 070, I want to block everything.

If you use a smartphone, there is a blocking program.
You can use hoo hoo or hoo hoo call.

If you write a post-call and it's spam, it pops up when you get a call saying spam.
Then, the spam phone company also called themselves and registered with a good number in advance so that they could get a call because it was not spam.
Fusco hasn't updated it yet, so we don't know when this spam will be caught.
