International roaming function needs to be enabled first, and prepaid users do not need to apply. By default, international roaming services in Hong Kong, Macao, Taiwan, Malaysia, South Korea, Vietnam and other regions and countries will be opened.

Post-paid users can log in to the online business hall /02oec, click on "Business Handling" > "International Business" > "International Roaming in Taiwan, Hong Kong and Macao", open or cancel the roaming rights of international roaming in Taiwan, Hong Kong and Macao, and choose to order superimposed packages.

Tips: The specific opening conditions are subject to local policies.
