Question 1

How does it work?

Accepted Answer

When you receive a withheld or private call, simply decline or reject it. OppBlock will then instantly unmask the caller and send you their number via push notification, SMS, and email. This allows you to know exactly who tried to contact you without answering anonymous calls.

Question 2

What information will I receive?

Accepted Answer

You will receive the anonymous caller’s phone number instantly via push notification, SMS, and email. In some cases, we may also provide additional information such as the network operator or caller location (where available).

Question 3

How quickly will I get the result?

Accepted Answer

Almost instantly, the caller’s number will be sent to you via push notification, SMS, and email within seconds of rejecting or declining the call.

Question 4

Is there a live demo?

Accepted Answer

Yes, our live demo feed shows our service working in real time. We encourage you to test it yourself! Simply call our live demo number with your own number withheld (by dialling 141 first). Watch as your number instantly appears on the feed, showcasing the speed and accuracy of our technology.

Question 5

Will the anonymous caller know I’ve unmasked them?

Accepted Answer

No. The caller will not be informed that their number has been revealed. The process is discreet, and the caller experience remains unchanged.

Question 6

Which networks are supported?

Accepted Answer

We work with all major UK pay monthly mobile providers. Also supporting some prepaid networks, such as giffgaff.

Question 7

Why does the service only work with certain mobile networks?

Accepted Answer

Our technology uses a network feature called Conditional Call Forwarding (Busy). This is standard on most monthly contract plans but isn't supported by all pay as you go networks. This is why compatibility can vary.

Question 13

Are my payment details safe?

Accepted Answer

Yes, your payment details are extremely safe. When you proceed to payment, you are redirected to Stripe's secure payment page, which you can verify by checking the URL in your browser's address bar. Stripe is one of the world's largest and most secure payment processors.

Question 14

Is my data secure?

Accepted Answer

Yes. All information is handled securely and in line with GDPR standards.

Question 15

What happens if I don’t reject the call?

Accepted Answer

If you answer a private or unknown call, OppBlock will not be able to unmask the number. You must decline or reject the call in order for the service to work.

Question 16

Can I block the unmasked number afterwards?

Accepted Answer

Yes. Once you have the number, you can block it directly using your phone’s call blocking settings or any additional call management services you may have.

Question 17

Do you automatically block excessively repeated calls?

Accepted Answer

Yes. To enhance your peace of mind and prevent notification spam, our system includes an automatic protection feature. If a single withheld number calls you excessively (specifically, after 50 attempts), we will automatically stop sending SMS and email alerts for that number. However, every call is still logged and remains fully visible in your dashboard call history, ensuring you never lose a record.

Question 18

Why do SMS alerts sometimes stop for a specific number?

Accepted Answer

To protect you from harassment and prevent excessive notifications from a single caller, our system has a two-stage throttling process:

Temporary Pause: After the first call from a new number, SMS alerts for that specific number are automatically paused for one hour. You will continue to receive push notifications and email notifications, and the call will be logged in your dashboard.

Permanent Stop: If the same number continues to call and triggers 15 SMS notifications, all future SMS alerts for that number will be permanently stopped. All subsequent calls from that number will still be logged in your dashboard and sent via push notification and email, but you will no longer receive text messages for it.

This system ensures you stay informed without being overwhelmed by a persistent caller. You can always view the complete call history by logging into your dashboard.

Question 19

Does it work internationally?

Accepted Answer

Our service is primarily designed for UK mobile networks. International compatibility may vary and is not guaranteed at this stage.

Question 20

How do I cancel my subscription?

Accepted Answer

You have full control to cancel your subscription at any time directly from your account dashboard. There are no long term contracts or hidden fees. Simply navigate to the account management section to make changes.
