Frequently Asked Questions

What to do if you can't find the option to block calls from outside your contacts?

If you can't find the block calls from outside your contacts feature on your phone, you can choose one of the following two methods to prevent unwanted or fraudulent calls:

• Use third-party call-blocking apps: There are many third-party apps available on Google Play Store or App Store that can help you block unwanted or fraudulent calls.

Why does a blocked number still ring on the second call?

Blocking a phone number on your device simply means prohibiting connections from that number to your device. However, this does not necessarily mean that the call will be completely blocked. There are several reasons why a blocked phone number may still be able to call your phone:

• If the phone number you blocked is stored in your phone's contacts and is synced with your accounts but that phone number is also stored in another account of yours (e.g., Google account), calls from that number may still ring.
• Some mobile service providers may allow users to block calls but not text messages or other forms of communication. Therefore, that phone number may still be able to send text messages or communicate through other channels.
• If the blocked phone number uses some call forwarding or messaging services, calls from that number may still ring.

Can you receive text messages if you block a phone number?

When you block a phone number on your device, typically you will not receive calls or messages from that number anymore. However, depending on the call blocking feature provided by the device manufacturer or mobile carrier, there may be cases where receiving text messages or some other services from the blocked phone number is still allowed.

In today's rapidly advancing world of information technology, receiving calls from unknown numbers is not uncommon. Some of these calls can be more than just annoying; they can pose a risk to users. With the guidance provided by Mytour above, hopefully, you have found a way to block calls from unknown numbers quickly and effectively to ensure absolute safety for your phone!
