The operational validity of your DataESIM plan initiates precisely at the moment your device registers with a supported network in the designated destination. For instance, if you're traveling to Hong Kong, you can complete the eSIM installation at your home location. The plan's duration will only begin counting down when your device successfully connects to a local carrier, typically upon arrival at Hong Kong International Airport (HKIA) or any other location within the covered territory. This ensures you maximize your data allocation from the first moment of actual use.
