How to compare a 10 GB eSIM for a two-week trip to Japan

Published 2026-11-03 · Dated catalog comparison

For a two-week trip, compare total-data plans with at least 10 GB and at least 14 days of validity. A 15-day package qualifies; its real validity should still be shown as 15 days. Keep daily allowances separate from pooled data.

Snapshot: 3 November 2026 (Asia/Shanghai). These are captured catalog base prices, not a current checkout quote. Promotions are excluded. EUR-to-USD comparisons use the catalog FX date of 2 November 2026. Prices, availability and plan conditions can change.

What this comparison shows

A Japan destination search can include regional packages when their actual country list includes Japan. A regional label is not a reason to exclude a plan, and it is not proof that every country in Asia is covered. Check the country list for the exact offer.

A 1 GB/day plan is not the same as a pooled 10 GB package: its daily cap can matter even if its nominal allowance over the trip is higher. Check reset timing, speed restrictions and activation conditions in the selected offer. This table intentionally excludes daily, unlimited and pay-as-you-go plans rather than treating them as equivalent.

How the rows were selected

From the captured Japan catalog, require coverage of JP, pooled data of at least 10 GB, validity of at least 14 days, and data-only service. Keep the lowest base-price qualifying offer per provider, using the snapshot FX rate to compare currencies. This is a sample from the listed providers, not the entire market. Seller, network, speed, activation and refund terms can differ; price alone is not a quality ranking.
