When you receive a withheld or private call, simply decline or reject it. MaskOff UK 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.

What is Silent Call Recording?

Silent Call Recording is a premium feature that allows you to capture an audio log of the unmasked call. When enabled, our system silently records the connection, providing you with an audio file for your records. You can activate this by selecting the 'Record' mode in your account settings.

What information will I receive?

You will receive the anonymous caller’s phone number instantly via push notification, SMS, and email. If you have the 'Record' package enabled, we will also provide a silent audio recording of the call attempt when available.

How quickly will I get the result?

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.

Is there a live demo?

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.

Will the anonymous caller know I’ve unmasked them?

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

Can I find out if my ex is calling me from a private number?

Yes. If your ex-boyfriend, ex-girlfriend, or a stalker is trying to hide behind 'No Caller ID', MaskOff UK will bypass the block. When you decline the call, their real phone number is instantly unmasked and logged in your dashboard so you have proof of the harassment.

Which networks are supported?

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

Why does the service only work with certain mobile networks?

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.

How do I install this app on my phone?

Installing MaskOff UK app is required to enable instant push notifications of your anonymous callers number. For iPhone/iOS (Safari): Tap Share, scroll and tap 'Add to Home Screen', confirm by tapping 'Add'. For Android (Chrome): Tap the three-dots menu, tap 'Install app' or 'Add to Home screen', follow instructions to confirm.

Do I need an app to use the service?

An app is not required for the service to work, as call details are sent via SMS and email. However, to receive instant push notifications on your device, you will need to install the web app.

How much does it cost?

To see all available plans, simply enter your number on our main page and press 'Start'.

Do you offer special pricing for returning customers?

Yes! We value our loyal customers. If you are renewing your subscription, log in to your account to see exclusive price plans available only to you.

I'm a previous client. Can I see who called me while my subscription was inactive?

Absolutely. By renewing your subscription, you will regain access to your dashboard, which includes the last known withheld call we recorded for you. Renew today to see who called.

Are my payment details safe?

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.

What happens if I don’t reject the call?

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

Can I block the unmasked number afterwards?

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.

Do you automatically block excessively repeated calls?

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 100 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.

Why do SMS alerts sometimes stop for a specific number?

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) and 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 are still logged in your dashboard.

Does it work internationally?

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

How do I cancel my subscription?

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.

I rejected a private call, but I didn't receive the unmasked number. What should I do?

If your mobile network temporarily fails to pass the forwarding data, our system proactively kicks in to find your call automatically. Keep your dashboard open. Within seconds of the call hitting our network, a PRIVATE CALL DETECTED alert will automatically appear on your screen asking if you just rejected a call. Simply tap Yes to instantly claim and unmask it. If you miss this automatic alert, you can still search for the call manually by clicking the UNMASK RECENT PRIVATE CALL button on your dashboard.

What is your refund policy?

If our system is unable to successfully unmask a private call, you are eligible for a full refund. However, once a private call has been successfully unmasked in your dashboard, the service has been rendered and we cannot offer a refund.

Is this the same as TrapCall UK or Call Reveal?

Yes, MaskOff UK operates on the exact same core technology as TrapCall UK and Call Reveal. While the US version of TrapCall does not function on UK networks, our platform, along with TrapCall UK and Call Reveal, are specifically engineered to be the definitive solutions for unmasking private numbers across all major UK mobile networks.

Does iCaughtYou still work in the UK?

No. iCaughtYou recently officially stopped supporting all UK mobile networks and completely abandoned the UK market. If you were a previous iCaughtYou user, MaskOff UK (along with our related platforms TrapCall UK and Call Reveal) is the only fully functioning alternative remaining for UK residents.
