Why Can’t I Block Numbers That Aren’t on My Contacts?

5 FAQs about Blocking Numbers That Aren’t on Your Contacts

Q1: Can I block numbers on older Android devices?

A: The availability of call blocking features on older Android devices may vary. Some older devices or operating system versions may not offer built-in call blocking options. In such cases, using a caller ID and spam protection app is recommended.

Q2: Will blocked numbers still leave voicemails?

A: Blocking a number typically prevents calls and messages from reaching you. However, it may not necessarily block voicemails. Check the settings of your specific device or app to determine if voicemails from blocked numbers are also prevented.

Q3: Can I unblock a number that I previously blocked?

A: Yes, you can unblock a number that you previously blocked. Follow the same steps you used to block the number and look for an option to remove it from the blocked list. Keep in mind that the steps may vary depending on the method you used to block the number.

Q4: Are there any risks associated with using firewall apps?

A: Firewall apps provide advanced control over blocking and filtering calls and messages. However, using certain firewall apps without proper knowledge and configuration may interfere with essential services and apps. It is crucial to understand the app’s functionality and the potential consequences before using it.

Q5: Can I still receive calls from blocked numbers if they use a different phone or SIM card?

A: Blocking a number on your Android device blocks the specific phone number, not the physical device or SIM card. If a blocked number contacts you from a different phone or SIM card, it will still be blocked as long as the phone number remains the same.
