What to Do If You Can’t Block Calls from Unknown Numbers

If you are unable to block calls from unknown numbers, here are three alternative solutions you can consider:

1. Enable Silent Mode or Airplane Mode: By enabling Silent Mode or turning on Airplane Mode, you can effectively mute or disable all incoming calls and notifications, including those from unknown numbers. However, this method also prevents you from receiving important calls, so use it with caution.

2. Install a Firewall App: Firewall apps, such as "RoboKiller" or "Call Control," provide enhanced call blocking features and allow you to create customized call blocking rules. These apps use extensive spam call databases and advanced algorithms to identify and block unwanted calls.

3. Change Your Phone Number: As a last resort, if you continue to receive a high volume of unwanted calls from unknown numbers, you can consider changing your phone number. While this can be a hassle, it provides a fresh start and ensures that only trusted contacts can reach you.

Bonus Tips

Here are three bonus tips to further enhance and optimize your call blocking experience on iPhone:

1. Report Spam Calls: When you receive spam calls from unknown numbers, make sure to report them to the appropriate authorities. This helps in building a database of known spam numbers and improves call blocking services.

2. Regularly Update Blocking Lists: If you are using a third-party call blocking app, regularly update the blocking list to ensure you have the latest spam call information. Outdated blocking lists may not effectively block new spam numbers.

3. Use Call Screening: Some call blocking apps offer call screening features that allow you to listen to the caller’s recorded name before deciding to accept or block the call. This can help you avoid unwanted calls without missing important ones.

The Bottom Line
