iPhones offer a simple approach to square guests by their numbers; along these lines, in the event that you get a spam call, you can without much of a stretch piece it. Be that as it may, consider the possibility that you simply didn’t need any calls from those troublesome obscure guests, and no guest ID numbers. Shockingly, there is no immediate path to that, yet. In any case, don’t stress, we have your back. Things being what they are, there is a basic work around that will naturally hinder any calls from obscure guests, and those “No Caller ID” numbers on your iPhone:
Block Unknown Callers using Do Not Disturb
1. On your iPhone, go to “Settings -> Do Not Disturb“. Here, flip the switch next to “Manual” to “On”.
2. Now, tap on “Allow Calls From“. By default, this would probably be set to “Favorites“. Change it to “All Contacts“.
3. Go back, and under the section that says “Silence“, select “Always“. This will ensure that you don’t get calls from unknown callers, even if you’re using the phone, and the screen is on.
That’s it. Since you have Do Not Disturb mode on, it will not notify you of calls from unknown callers, and no caller ID numbers. You can now get back to working, and not get bothered by anyone who is not in your contacts list. No more of those pesky spam calls for you! Enjoy!
Bonus: Repeated Calls
The only drawback of using a workaround such as this one, is that you will not get notifications for genuine calls that are made from a number which is not in your contacts list. While that may be okay, it could be a problem if the other person is in an emergency, and needs your help. So, in the Do Not Disturb section, make sure that you turn on “Repeated Calls“.
All this does, is, if someone calls you from an unknown number, and then calls you again, within three minutes, your iPhone will not block that call, and will notify you about an incoming call. So, unless spammers repeatedly call numbers in your area, you can safely turn this on, and only be bothered by unknown callers, who really do need to talk to you.
