When can I activate my eSIM?

Please activate your eSIM in Japan since the validity period starts once your eSIM is activated regardless of your location. Airports such as Haneda, Narita, Itami and Kansai International provides free wifi access so you’ll be able to download your Japan Wireless eSIM there.
