Effectively Preventing Spam Calls: Tips for Android and iPhone

Smartphone users are increasingly confronted with spam calls that are not only annoying but also pose financial risks. To protect themselves from these unwanted calls, both Android and iPhone devices offer various features that help identify and block spam calls. On Android devices, users can activate the "Block spam and scam calls" feature. This option can be found in the settings of the phone app. When this feature is enabled, calls from numbers identified as spam are automatically blocked.

Google utilizes a comprehensive database that is regularly updated to capture new spam numbers. iPhone users also have the option to block spam calls. The "Silence Unknown Callers" feature can be activated in the settings under "Phone." Calls from numbers not saved in the address book will be silenced and displayed in the call list, allowing the user to decide whether to return the call. In addition to the built-in features, users can also install third-party apps specifically designed for identifying and blocking spam calls.

These apps often use community feedback and data analysis to recognize suspicious numbers. Popular apps in this area include Truecaller and Hiya, which are available for both Android and iOS. Another important aspect is the ability to report callers. Both Android and iPhone provide features to report suspicious numbers. These reports help improve the providers' databases and block future spam calls more effectively.

Users should be aware that reporting spam calls benefits not only themselves but also other users. Utilizing call identification services can also be helpful. These services display the name and origin of the caller before the call is answered. Many mobile providers offer such services, often available for a monthly fee. Users should inquire about their provider's offerings to gain additional security.

Another preventive step is to avoid disclosing personal information over the phone. Users should be cautious when contacted by unknown numbers and refrain from sharing sensitive data such as bank information or passwords. Fraudsters often use fake identities to build trust and steal information. Combating spam calls is an ongoing process that requires both technological solutions and user awareness. The combination of built-in features, third-party apps, and cautious handling of calls can significantly reduce the number of spam calls. According to a YouGov survey from 2025, 45% of respondents reported regularly receiving spam calls.
