Frequently Asked Questions

How many data plans does MobileSIM offer for Japan?

MobileSIM provides 12 single‑country data plans and 14 multi‑country data plans that cover Japan. The single‑country lineup includes both fixed data‑cap plans—where a set amount of data is unlocked for the entire validity period—and daily data cap plans, which reset each day. Across all Japan‑focus plans, prices range from about $4.50 to $185, with data caps spanning from 1 GB up to 100 GB, giving travelers a broad selection to match travel length and usage requirements.

Does MobileSIM offer unlimited data eSIM for Japan?

MobileSIM does not provide a true unlimited data eSIM for Japan. The plans that carry the word “Unlimited” are limited to 3GB per day; once the daily allowance is exhausted, data speed is throttled to 1000 kbps. For travelers who need more predictable usage, MobileSIM offers fixed‑data options such as a 20GB plan valid for 30 days, priced at $25 USD, and a larger Asia 100GB plan valid for 180 days, priced at $185 USD. These fixed‑plan options may be more cost‑effective for users who consume a lot of data over a longer period.
