Travel eSIM price index: 198 destinations compared

What the index actually measures

A country-level median cost per gigabyte compresses a range of local retail offers into one number. Each destination is weighted once in the global figure; it is not a pooled median over every plan and it does not measure data speeds, validity, taxes, phone compatibility or final checkout cost. Because one seller publishes the entire sample, “cheapest country” means cheapest within this TripoSIM sample—not cheapest worldwide or across competitors.

This distinction matters to a traveler comparing a week in Japan with a week in Egypt. The same $/GB figure can represent a low-priced long-validity plan, a promotion that expires before travel, or an offer with a restricted network. An eSIM cannot be selected responsibly using this one metric. The data are most valuable for benchmarking destination-level variation and forming a shortlist to check on the actual retail page.

Regional patterns in the snapshot

Regional rows are descriptive aggregates: the 10 GB column is the median listed 10 GB price across destinations in that region, while the cost-per-GB column uses the separate country medians. Do not divide one column by another to reconstruct an individual SKU. A regional eSIM product may have a completely different price and list of eligible countries. The region labels in the research dataset are editorial groupings, not a guarantee of roaming coverage or EU regulatory treatment.

Why 1 GB versus 10 GB needs careful interpretation

Among 194 country records with both sizes, 189 show a lower per-GB figure for the 10 GB size. This is a comparison of observed tier fields, not proof of a bulk discount that every customer can claim today. A €- or $-denominated traveler with a short, mostly Wi-Fi trip may spend less in total with a small plan despite a higher unit price. A heavy-video traveler might require more than 10 GB and must compare exact duration and usable speeds before paying.

For an illustrative seven-day moderate-use trip at 0.7 GB/day with a 20% reserve, the data estimate is 5.88 GB. A recorded 10 GB tier clears that capacity threshold. But its price cannot become a legitimate trip quote until the validity covers seven days, the country is supported on that precise plan, hotspot and activation conditions fit, and the price is confirmed at checkout. The previous V8 model incorrectly treated separate tier prices as freely combinable; this release removes that assumption.

Five low-median destinations in this catalog

These are the lowest country-level median values in the provided dataset, not recommendations and not the best travel eSIM vendors. A low median can reflect several inexpensive catalog entries without implying comparable service quality. Check the named local networks on the exact plan, but remember that the country list may contain networks belonging to different SKUs. A network listed for one product may be unavailable on another.

A practical four-step purchase check

First calculate how many gigabytes you need using your normal data usage and a buffer. Second compare only single eligible offers whose stated validity covers your whole trip. Third verify total payable cost including any relevant taxes or exchange-rate differences, and check whether your home carrier already includes roaming. Fourth inspect the exact SKU for fair-use throttling, hotspot restrictions, top-up eligibility and activation rules. After completing those checks, compare cost per usable GB as a secondary metric rather than the first filter.

How this research can be improved

The next edition should publish an immutable timestamped dataset, change log, offer-level availability and a clean distinction between observed catalog data and completed-order pricing. It should include checks against current checkout records, and a sampled independent field-testing program with network identifiers, tested devices, dates, cities and test limitations. Without these, the proper claim is “first-party country price index,” not “best eSIM price in the market.”
