SimOptions eSIM Data Plans for Japan

SimOptions does not provide an unlimited data eSIM for Japan. Instead, the provider offers a range of fixed‑data plans, such as a 50GB plan valid for 30 days, a 30GB plan also valid for 30 days, a 20GB plan that lasts 30 days, a 10GB plan for 15 days, and a 5GB plan for 7 days.

For travelers who need a lot of data, purchasing one of the larger fixed‑data packages can be more cost‑effective than a hypothetical unlimited option, especially if the user's usage does not exceed the plan limits.

SimOptions does not offer a Japan eSIM plan that includes a phone number or SMS capability. All plans from this provider are data‑only, providing internet access without voice calls or text messaging as part of the SIM.

Travelers can use popular VoIP apps such as WhatsApp, Telegram or iMessage, which operate over the data connection, to make calls and send messages without needing a local phone number or SMS service.

SimOptions offers seven single‑country data plans for Japan, with prices ranging from $4.50 to $44.90 and data caps between 1 GB and 50 GB. These plans are fixed‑data packages and no multi‑country options are available.
