How we compare
How these prices
are compared.
- 01
Match the allowance and validity.
We match country, total data allowance and validity in days, using the supplied USD price. We show a comparison only when PikoeSIM and at least one competitor have that exact allowance and validity. Fixed total-data plans only: unlimited, daily allowances, PAYG, regional/global, trials and top-ups are excluded.
- 02
Compare the recorded prices.
When a provider lists several offers for the same allowance and validity, we show its lowest price. Highlights need at least two exact prices and verified inventory for all four providers. Ties share the highlight. Price differences use the highest-priced matching offer.
- 03
Check the source.
Open a provider’s country page to confirm the checkout price and product terms. Matching data and validity does not imply equal coverage, speeds or features.

questions.
Why do some providers appear without a price in these comparisons?+
A missing price means no exact match for that data and validity in the displayed records, not absence of Japan service. Yesim and Roamless miss several tiers; MobiMatter lacks the 1 GB, 30 days match.
Where is MobiMatter cheaper than PikoeSIM?+
Only on the 15 GB, 30 days tier, where MobiMatter charges $11.99 against PikoeSIM's $12.28, a gap of $0.29. On every other compared row, PikoeSIM is lower.
Should I compare total price or per-gigabyte rate?+
Check both. The 12 GB, 30 days option costs $5.42 total, or $0.45 per GB, while MobiMatter's total is $9.99 or $0.83 per GB. A lower total does not prove better coverage.
