Frequently asked questions

What is a robocall?
A robocall is an automated phone call that delivers a pre-recorded message through a computer. While some can be legitimate (like appointment reminders), many are telemarketing scams or phishing attempts.
Will blocking robocalls prevent legitimate calls?
Using features like Silence Unknown Callers on iPhone or Call Screen on Android can sometimes block or screen legitimate calls from numbers not in your contacts. It's a balance between stopping unwanted calls and potentially missing a call you wanted. You can always review recent blocked calls or listen to screened calls.
Are third-party call blocking apps safe to use?
Many third-party apps are reputable and offer excellent protection. However, always research an app before downloading. Look for apps with good reviews from trusted sources, and be aware of what permissions they request. Avoid apps that seem overly intrusive or demand too much personal information.
