Spam calls should be a bygone concern, but unfortunately they’re still a plague many of us deal with. Services like Truecaller have helped with caller identification and spam filtering for years. But since Android and iOS have gotten great at handling spam calls on their own, you don’t need to rely on a third-party app — much less pay a subscription — to avoid unwanted callers.
In addition to functions on your phone, your carrier may offer its own spam protection features. Depending on the company, these might be enabled by default. If not, check your online account or the carrier’s app for a spam protection toggle.
Filtering unwanted calls on iPhone
If you have an iPhone, navigate to Settings > Apps > Phone. The most important option is under the Call Filtering section; enable Spam and calls that your carrier identifies as junk won’t ring. They’ll be automatically sent to voicemail, and in the Phone app’s Calls tab, they appear under the Spam section (accessible under the top-right button).
To further keep your call logs tidy, enable the Unknown Callers option in the same Settings box. With this, recent calls from non-contacts appear under the Unknown Callers section (available via the mentioned top-right button in the Phone app). Use Mark as Known to remove a given number from this section if needed.
Back on the Settings page, review the Screen Unknown Callers section, where you have three options. Never is the default, where every incoming call rings normally. The most aggressive approach is Silence, which mutes all incoming calls from numbers not saved in your contacts and sends them to voicemail. You can view these silenced calls on the same Calls tab of the Phone app.
Ask Reason for Calling is a good middle ground; with this, your iPhone will screen unknown callers and ask them why they’re calling. You’re able to view a live transcript of the caller’s response on your screen and decide whether the call is worth answering. Call Screening is only available in select countries on iPhones running iOS 26 or newer.
While you presumably have friends and family saved in your contacts already, make sure to save any other numbers that contact you regularly, like doctors’ offices or work clients. These options are great for shutting up spammers, but you’ll need to be a little more vigilant to avoid missing legitimate calls from unsaved numbers.
