Call Screening Cuts Spam Calls for iPhone Users After iOS 26 Introduction
By Drooid · · How we work
Core Event
Apple added a Call Screening option to the Phone app in iOS 26, allowing users to require callers to state their reason for calling before the call is connected. The author of a recent 9to5Mac column reports that enabling the “Ask Reason for Calling” setting in early 2026 has stopped all spam and scam calls from reaching their iPhone, while still permitting genuine callers to be identified and answered.
Background & Context
The feature debuted with iOS 26, a year before the release of iOS 27, which introduced additional updates but did not alter the screening functionality. The author notes a noticeable rise in unsolicited calls earlier in the year, including impersonations of mobile carriers and job-scam solicitations. Although the writer had previously protected their number by using fictitious numbers on web forms and relying on a UK regulator’s pool of unused numbers, the increase in robocalls eventually prompted activation of the screening tool.
User Experience & Impact
Since turning on Call Screening, the author says they receive at least one spam call per week but none bypass the filter. Most automated callers hang up when asked to state a purpose, and the few that provide a reason are immediately recognized as scams and rejected. The writer acknowledges that a small number of legitimate calls have been filtered, but those callers also supplied a reason, enabling the author to answer after verification. The personal account suggests that the feature can dramatically reduce unwanted calls without impeding access to authentic contacts.
Enabling the Feature
The author recommends the following steps for iPhone owners who have not yet activated Call Screening: open the Settings app, scroll to the Phone section, and select “Screen Unknown Callers.” This activates the “Ask Reason for Calling” prompt for incoming calls from numbers not in the user’s contacts. The writer’s experience indicates that the setting is straightforward to enable and can substantially improve call-screening effectiveness.
