How to block robocalls and unwanted calls

Are you tired of all the spam calls you get? Lawmakers have passed laws to address the problem, but there are steps you can take yourself. Android devices and iPhones have built-in features to block specific phone numbers, while mobile carriers offer their own blocking tools.

Several third-party apps, including Hiya, RoboKiller, Truecaller, and YouMail, also allow telemarketing calls to be blocked. And you can also register your phone number with the FTC’s Do Not Call Registry, although that won’t stop crooks and reputable telemarketers from calling you. Let’s see each option.

(If you also receive spam bots, there are steps you can take to block themblock them, too much.)

Block numbers on iPhone

Robocallers browse thousands of phone numbers, and many include the same phone prefixes as your own phone number. To block them when they arrive on your iPhone, open the Phone app and tap Recent. Press the Info icon next to the number you want to block and choose Block this caller> Block contact.

The number is now blocked, but spammers have a habit of jumping from one number to another, so this remedy is only useful if the caller uses the same number multiple times.

Silencing unknown callers

With iOS 13 or higher installed on your iPhone, you can take a more effective but drastic step to crack down on spam calls. Go to Settings> Phone> Silence unknown callers and turn on the switch to Silencing unknown callers.

This feature automatically silences all calls from numbers that are not in your contacts. Calls are sent to voicemail and appear in your Recents lists so that you can return the call if it is legitimate.

Block numbers on Android

Tap the number you want to block and look for the command that says block and / or report as spam. You then confirm the order to block the number.
