Unwanted advertising – or spam – is clearly nothing new. By the time we got leaflets and brochures in the mail, that was all we had. Now that we are more online and even on our smartphones, spam is haunting us in our emails and on our phones. While email services like Gmail have a very robust email spam filtering system, the same can’t really be said for our phone calls. So how do you block spam calls on iPhone?

To block spam calls on an iPhone, the best approach is usually to block the number once you have called and identified yourself as an unwanted caller. You can enable the Silent Unknown Callers feature to only receive calls from people in your Contacts app, or alternatively, add your number to the Do Not Call registry.

block the number
Once someone calls you, and you find out it’s a spam caller, the best and most effective thing you can do is simply block the number. Obviously, if this is a call center, and they are calling from multiple phone numbers, then blocking one number will not solve the problem immediately. But if it’s a small business operation with a phone, blocking that number solves the problem immediately.
We have previously published a tutorial on how to block a phone number on iPhone. But the short answer is that you need to go through the call log or, if the person is in your Contacts app, you can go from there. then tap block this caller,
Use the Silence Unknown Callers feature
If you want to take a more comprehensive proactive approach to spammers, you can create a policy of not answering calls from people you don’t know. For this, you can enable what is called silent unknown callers (No, this does not include hiring a hitman.)
Again, you can read about it in our article about blocking calls on iPhone, but it’s fairly simple to turn it on. just go Settings-> Phone and scroll down silent unknown callers, Once toggled on, all calls not registered in your Contacts app will go directly to voicemail and appear in your recently missed call list. If you don’t have voicemail enabled, it will just play silently.
Add Your Number to the Do Not Call Registry
The third option is to add your number to the Do Not Call registry. Don’t consider this a bulletproof option, however, as it has flaws, and some unethical companies ignore the DNC list altogether.
Most legitimate companies will follow the national Do Not Call list and will not call if you are registered. However, since 2009 the FTC has seen a significant increase in the amount of illegal sales calls, including companies that ignore the DNC listing.
Drawbacks include the restriction applying only to sales calls — and only to companies you haven’t done business with before. So calls from politicians and phone surveys will still come.
Many other countries also have Do Not Call lists. Great Britain has a very British-sounding telephone preference service, Germany has Robinsonlist, and so on. Simply Google “do not call” and the name of your country to get your country’s version.
Use third-party apps
There are some third-party apps that seem to be good at blocking spam. However, the one that caught my eye was Sync.me. When spam calls come in, they will be marked as such on your iPhone screen.
Available as both a free option and a paid option ($19.99 per year), it claims to have a high success rate. It will instantly block all known spammers, and those who get through it will be recognized on screen with a picture and even their social media profiles!
However, you have to give it permission to access your phone. go for Settings-> Phone and scroll down Call blocking and identification, Toggle on the new third-party app you just installed.
