Field tests: our real mobile speed measurements across Asia

Every point on the map is a real mobile speed measurement, taken on location with our eSIM. No estimates, no theoretical maps: numbers gathered in person.

40 measurements

Direct answer

Our field database contains 40 mobile measurements taken across 40 locations under real travel conditions. The most recent measurement was taken on September 10, 2026. Results can be explored by country, city, location and operator. They represent our measurement points and not nationwide coverage.

Why field tests

Most eSIM comparisons rely on spec sheets and theoretical coverage maps. We do the opposite: we measure on the ground, where you will actually travel. A crowded airport, a remote beach, a moving metro do not deliver the speeds a map suggests.

How we measure

Every measurement is taken on location, with our own eSIM, in real travel conditions: a precise place, a time, a connected network. We record download and upload speed, latency, then publish the result unedited.

The aggregates (median, mean, extremes) build up as we travel. The more measurements a destination has, the more reliable its median becomes. The median resists the extreme values of a single test better than the mean.

✓ Every published measurement comes from our team or a verified purchasing customer, and is manually reviewed before publication. No personal data (email, identity) is ever published.
