EtravelSIM eSIM Data Plans for Japan

EtravelSIM does not provide a truly unlimited high‑speed data plan for Japan. All of its Japan‑specific plans list a fixed data allowance, with the “Unlimited” titles actually meaning 4GB per day and a reduced speed of 128 kbps after that limit is reached.

Customers who need more data will need to choose a fixed‑data plan. For example, the Tokyo eSIM – WAC 2025 Special 50 GB plan gives 50 GB for 30 days, and the Travel eSIM for Asia 50 GB plan offers 50 GB for 30 days as well. These plans represent only a subset of available options; eSIMDB does not sell plans directly, so customers should check EtravelSIM’s current catalog for the full range.

EtravelSIM does not offer any eSIM plan for Japan that provides a phone number or SMS capability. The provider currently offers only data‑only eSIM plans for Japan. Travelers who need voice or messaging can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection.

EtravelSIM provides 15 single‑country data plans for Japan and 8 multi‑country plans that include Japan among other destinations. The single‑country options cover a range of data allowances from 1 GB to 50 GB, while the multi‑country plans offer a similar breadth of data amounts. Prices across all plans start at about $4.50 and can go up to roughly $109.99. Some plans are fixed‑data packages, giving a set amount of data for the validity period, whereas a subset offers daily data caps, allowing a set amount of data to be used each day of the validity period.
