Call Guard

General features

Q1: If I subscribe to both Call Guard and Connecting Tone, will callers hear my favourite Connecting Tone?

Yes, if the call can get through to you, the caller will hear your favourite tone from Connecting Tone. If the call is blocked by Call Guard, the caller will hear a message from Call Guard, without the Connecting Tone.

Q2: If I forward my calls to another number, will the Call Guard service still block junk callers?

Call Guard will only block junk calls for the number with the Call Guard service. The other number will still continue to receive unwanted calls.

Q3: If I forward calls to a number with Call Guard, will those calls be filtered too?

Yes, Call Guard is able to filter all incoming calls for any phone number forwarded to a number with the Call Guard service.

Q4: If I have unsubscribed from the Call Guard service, can I retrieve my previous number list when I resume my subscription?

Yes, we will keep your number list for 3 months.

Q5: If I transfer my SIM to another smartphone, do I need to re-enter the number list?

No, the number list is stored in the cloud. All you have to do is to download Call Guard app to your new smartphone and your number list will be there.

Q6: When I turn on the "VIP List" feature, will it affect other features that I have already switched on?

Yes. The "VIP List" feature will override all other features in use and only allow callers on your White List to reach you.

Q7: Can I use the Call Guard app on WiFi?

Yes. All you need to do is log in.

Q8: When I turn on Bar Withheld Numbers for both local and international calls, I can't receive my friend's calls from overseas. Why?

The caller ID of some international calls may be hidden because of the IDD setting of the provider. If the caller ID of the international call is hidden, it will be blocked. If you want to receive international calls from a hidden caller ID, you can simply turn off the Bar Withheld Calls from overseas feature.

Q9: Can I view my history of blocked junk calls?

Yes, the Call Guard app allows you to check all blocked junk calls in the past 30 days. You may call back or unblock any numbers by using the Exceptional List function.

Q10: If the incoming call which originates from outside Hong Kong does not have a caller ID, will I still be alerted by "Overseas Call Notification"?

Yes, you will be reminded even if there is no caller ID.

Q11: Which platforms support Call Guard?

Call Guard can be used on smartphones running iOS 5.1.1 or above, Android 2.2 or above, Windows Phone 7.5 or above and BlackBerry® 6 or above.


Q1: Can I use Call Guard when I am abroad?

Yes, you can use Call Guard locally and abroad. It will not use data unless you have to download the app, report a junk call or change your blocking preferences. We recommend downloading it and setting your preferences before departure. If you would like to use it overseas, standard roaming data charges will apply. Please click here for details. To enjoy better value data roaming as well as improved control over your spending, we recommend subscribing to our Roaming Data Day Plan.

Block junk callers

Q1: I have received an SMS saying the number I reported was not verified as a junk call. Why?
A1: All reported numbers are checked by our verification team to prevent false reporting and protect user rights. If you received an SMS, the number you reported did not qualify as a junk call. Please only submit junk callers and follow the Terms & Conditions .

Q2: How can you guarantee your list of junk callers is error-free?

Users can report a junk call from their last five received calls without needing to input any numbers, which helps minimise false submissions. All reported numbers are verified to prevent false reporting and protect user rights.

Q3: I reported a junk caller that was not verified. This caller continues to disturb me. What can I do?

You can add that number to your Personal Blacklist, which is your own personalised blocked list. This user-contributed junk call list is available to all Call Guard subscribers. Our verification team works to protect user rights by screening false reports, so your submitted number is not added to the junk call list.

Q4: I am expecting a call, but that number might be blocked by the Junk Call feature. What can I do?

You can add that number to Exceptional List in the Junk Call feature. That number will then be able to reach you even when the Junk Call feature is turned on.
