What is DataESIM connectivity performance on long-distance Kazakhstani train journeys?

During extended train journeys in Kazakhstan, such as the route from Almaty to Astana, DataESIM connectivity will be intermittent. While strong signal is typically available when passing through towns or populated settlements, vast stretches of uninhabited steppe will result in periods of no or significantly degraded internet service. Users requiring continuous connectivity for critical tasks should anticipate these outages and plan accordingly, potentially downloading content or preparing offline work.
