Your eSIMFlyer Mongolia plan is exclusively for use within Mongolian airspace and land. The legendary Trans-Mongolian Railway journey, while incredible, crosses international borders. Once your train departs Mongolia and enters Russia (Siberia) or China (Inner Mongolia), your eSIMFlyer connection for Mongolia will cease. For this epic rail adventure, we highly recommend securing a regional eSIMFlyer package that covers all three countries, ensuring continuous connectivity for sharing your journey updates.
