Roaming Tips

The following tips will tell you the major points to note while traveling abroad with your handset and how to avoid unnecessary roaming charges so as to enjoy a hassle-free journey.

 

1.  Log on to an overseas network while roaming

While overseas, your mobile phone automatically selects a roaming network for you. If your handset cannot be connected to a local network, you can select a network using the "Manual Network Selection" function. Please refer to handset manufacturers' user manual or call our hotline at 2888 1010 for details.

 

2. Making calls to Hong Kong / other destinations when you are abroad

Note: If the [+] symbol is not available, you can try common international direct dialing numbers like [00], [011], or [001].
For most area codes, the leading [0] should be omitted when dialing with an IDD number.

Sending SMS: Select "Write Message" on your phone → Enter content → Enter:

3. Quick access to Voicemail

To access your voicemail quick and easy while roaming, simply press [*100] before the usual voicemail access code *988. Here is how you should dial: 

OR

After sending this command, the system will call you back within a few seconds. Answer the call and you will be connected to Voicemail directly as you do in HK.

You don't have to enter your mobile phone number and can skip the password, as simple as when you're in Hong Kong. Charges will follow the HomeCall tariff.

To enjoy the above service, you need to sign up to Roaming Call Management Service. Please call 2888 1010 for details on Roaming Call Management Service and Voicemail. 

• Note: 
  In destinations where Roaming Caller Number Display Service (CND) is available, the voicemail number [+85298866622] will be shown when the system calls back to indicate it is from your voicemail.
• Remember to cancel call forwarding before you dial to Voicemail.

5. Avoid unnecessary roaming charges

Cancel call forwarding
Please cancel all "call forward" functions, including "busy", "no answer" and "unreachable call forward" functions before departing Hong Kong in order to avoid double roaming charges that result from activation of the "call forward" function while travelling. If you need to call forward your calls, please use "divert all calls" to call forward to any Hong Kong number or your voice mail box. You can then listen to your voice messages at your convenience while roaming. To cancel "call forward" function, simply dial:
