Can I activate my EastESIM for Macau after crossing the border from China?

We strongly advise activating your EastESIM for Macau before you cross the border, ideally while you still have a stable internet connection. The border crossing from mainland China (e.g., from Zhuhai) into Macau can result in an abrupt loss of your Chinese network signal. By activating your EastESIM beforehand, your device will automatically detect and connect to a local Macau network (like CTM or SmarTone) as soon as you enter the Special Administrative Region, providing instant connectivity without any hassle.
