How to block spoofed calls

[abbby]

Is there a way to block spoofed calls? Had been receiving the calls every other day and the number is always different. Can I block +65? Since there's no longer such prefix used.

Yeah, they're a real pain. I've never got a +65 call that wasn't a spoof call, so I've just stopped answering them altogether. If you block them, you won't have a record of your incoming +65 calls, which means on the off-chance there was a legitimate +65 call amongst them, you won't be able to bring up the details, FWIW.

Then again, I only get them a couple of times a month.

Every time I thought was a legit call it goes with an automated message, 'This is DBS...' I tried blocking +65 on my phone setting, but it doesn't work.
