Internet location
Hong KongWhat this means
Your eSIM connects to local networks in Japan, but your data joins the internet in Hong Kong. Apps and websites see a connection from Hong Kong, so some may show that country’s language, prices or content.
Maps, GPS and taxi apps still know where you really are, because they use your phone’s location, not your internet location.
Some services, such as ChatGPT and Google Gemini, aren’t available from Hong Kong. If you need them, choose a plan whose internet location isn’t Hong Kong.
