      How will I be charged if I made calls, sent SMS or browsed the internet while roaming?

      For Postpaid subscribers, charges will be reflected in your upcoming bill statement. For Prepaid subscribers, the charges will be directly deducted from your credit balance.

      What are the rates for roaming calls / SMS / data charges?

      The charges are based on the countries and operators you have selected. For the full list, please visit u.com.my/international-roaming/roaming-overseas.

      Are there any peak/off-peak hours to make an international call?

      Yes, charges would vary for peak and off-peak hours according to our roaming partner’s charges.

      Will I be charged for answering calls while I'm roaming?

      Yes, you will be charged if you answer any calls while you are roaming. The charges will vary according to the country of originating calls.

      Is there any password required to retrieve my voicemail while roaming?

      This will depend on how your voicemail is set up.

      To check your voicemail, just dial +6018 388 1311.

      Yes, you will be charged for retrieving your voicemail.

      If I am a postpaid subscriber, is there a minimum credit required to make or receive calls while roaming?

      Yes, this will depend on the subscribed rate plan. However, you are advised to settle your outstanding bill before you travel to avoid any interruption to your mobile line.

      If I am a prepaid subscriber, is there a minimum credit balance required to make or receive calls while roaming?

      You can contact our Customer Service centre at +6018 388 1318 to suspend your line immediately to avoid any unauthorised usages.

      I have already checked my phone’s signal and it shows good coverage. Why am I still unable to make any calls to Malaysia?

      The stability of roaming services is subject to the local operator’s network. Try moving to another area with a stronger signal and retry calling.

      While roaming in China, I have noticed that most of my calls to Malaysia could not be connected. Why?

      Due to an intermittent network issue faced by our partners in China - China Unicom, outbound calls with the “+” prefix will not be able to go through. 

       

      You can still make calls to Malaysia by using “00” as your international dialling prefix until further notice.

      Do I need to pay a deposit if I am activating IDD?

      No deposit is required for Malaysians, but a deposit of RM200 is required for foreigners.

      Will my IDD call be charged in Ringgit Malaysia (RM) or in the currency of the country I called?

      Your IDD call will be charged in Ringgit Malaysia (RM).

      How much does an IDD call cost and how will it be reflected on my itemised bill? Are the charges based on the length of the call, the time that the call was made, or the destination country? Is there a flat monthly rate?

      Your call charges will come under the “International” section in your bill, which records all the calls you made to destinations outside of Malaysia. Then you will see the name of the destination country in your bill.

      Can I suspend or deactivate my IDD service?

      Yes. Please contact your Enterprise Account Manager or Enterprise Partner or visit the nearest U Mobile service centre

      If I make an IDD call to a mobile phone, will I be charged differently from if I make an IDD call to a fixed line?

      Please view our voice rates for more information.

      Will I get charged if I cannot reach the person I am trying to call?

      No. Unless the call is answered by your recipient's voice mail or IVR, you will not be charged.

      We’re constantly offering new promotions, so be sure to check our website from time to time, so you can see the latest rates. You may also see changes in IDD rates on your bill.

      No.

      How do I activate IDD?

      Please contact your Enterprise Account Manager or Enterprise Partner or visit the nearest U Mobile service centre to activate this service.

      What are the benefits of using WiFi Calling?

      WiFi Calling allows you to use your existing U Mobile number to make and receive calls using a WiFi connection. Your WiFi hotspot effectively becomes a U Mobile network tower. Enjoy huge savings while overseas when calling Malaysian numbers at a local call rate with no roaming surcharge.


      Effective 22 January 2025, VoWiFi is available while roaming in all countries except Myanmar. Calls to Malaysian numbers while in Myanmar will be subjected to roaming surcharges.
