GigSky eSIM Data Plans for Japan

GigSky does not provide an unlimited data eSIM plan for Japan. Travelers have access to fixed‑data options instead. For instance, GigSky offers a 100GB plan valid for 180 days, a 50GB plan valid for 180 days, and a 20GB plan that can be purchased for either 180 days or 90 days. These plans give users a predetermined amount of high‑speed data while they are in Japan. Selecting a fixed data plan can be more cost‑effective, especially for moderate or moderate‑heavy data usage, and the plans include coverage that reaches Japan among other countries.

GigSky does not provide a phone number or SMS capability for its Japan eSIM plans. The provider offers only data‑only options in this country, so travelers cannot receive or send SMS or make voice calls that use a local phone number. However, they can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to communicate.

GigSky offers five single‑country data plans that are valid only in Japan, and twenty‑nine multi‑country plans that include Japan along with other destinations. The plans vary in data volume from as little as 100 MB up to 100 GB and in price from $0.00 to $332.49, with validity ranging from 1 to 180 days. Single-country bundles keep the data usage restricted to Japan, while multi‑country bundles allow the same data allowance to be used across several countries in a single contract.
