What’s your take over unknown callers? Well, if it’s from an HR of a big-shot company or a long-lost friend, we might enjoy it a lot. On the contrary, if it’s a marketeer or phishing call, that angers us to no extent. But hold your horses because there are ways you can block no caller ID on your iPhone!
I have lined them up for you. So, scroll through.
- Silence Unknown Callers
- How to permanently block someone using contacts
- Employ Carrier’s call filter service
- Use Focus or DND to block no caller id calls temporarily
- Use call-blocking apps
As the name suggests, the setting blocks all calls from numbers not stored in your contacts. The good thing is that call received from an unknown caller is directed to a voice mail and registered in the recent call list. And you can go and check the calls later.
- Open Settings → Phone.
- Scroll and tap Silence Unknown Callers.
- Toggle on the switch.
However, it also means that an important or emergency call from an unknown number (HRs, long-lost friends, etc.) is also blocked, which could be problematic. I suggest using the setting wisely and ensuring all important people are added to your contacts.
Note: There is a loophole in this method. If you have messaged someone or received multiple calls from the number, Siri identifies it as suggested contacts and thus, allows them to pass through.
When you are getting tons of unnecessary calls from a company or someone, you can choose to block them permanently. Here’s how you can permanently block no caller ID calls
- Launch the Phone app → Recents tab.
- Look for the number and tap the i icon next to it.
- Scroll down and select Block this Caller.
- Tap Block Contact to confirm.
While this is the most fail-safe way, blocking each number individually can be irritating. Moreover, marketers or malicious parties can call from different numbers, so you might have to keep the block cycle on and on.
Another smart way to stop no caller ID calls on iPhone, especially marketing or phishing calls, is to invoke a DND-like service from the carrier. Notably, the method varies from provider to provider, and you’ll have to Google or contact the network provider to enable the service.
And while this is one of the best ways to block pesky calls, not all network providers support the service in all regions. So, you’ll have to check the status of the service before you proceed.
When you want to silence unknown callers for only a particular time frame, wherein you are working, resting, partying, etc., Focus/DND is your best bet.
I. Enable Focus on iPhone running iOS 15
With iOS 15, Apple introduced a smarter and versatile version of DND, Focus. Now, when you set a focus, you can decide whose call will come through. Here’s how to do it.
- Go to Settings → Focus → Choose a Focus.
- Tap People → Calls From.
- Here, select All Contacts.
You can also tap + Add, Favorites to add selected contacts. When you turn on the focus mode, calls from an unknown number or contacts not added to the list will be silenced until you turn off Focus.
II. Enable DND on iPhone running iOS 14
If you are sticking to iOS 14, you can still stop no caller ID on iPhone via DND. Like Focus, once you set up DND, only allowed calls will ring your iPhone, the rest will be silenced.
- Go to Settings → Do Not Disturb.
- Tap Allow Calls From and select All Contacts.
So, when you enable DND, all unknown calls are blocked. Notably, you can also choose a set of favorite contacts and allow them to filter through.
Yes, there is an app for this as well! From Robo Shield to Truecaller, there are tons of call blocking apps that can help stop those annoying spam calls. All you’ll have to do is, go to Settings → Phone → Call Blocking & Identification → toggle on the switch next to the app.
Now, whenever you receive a call from an unknown number, the app will run it against its list of spam callers. If a match is found, it will label the call and silence it, depending on your selected setting.
