This specific plan is valid only within Mongolia. The Trans-Mongolian Railway is a popular journey connecting Russia, Mongolia, and China. Once the train crosses the border into Russia (Siberia) or China (Inner Mongolia), your connection will stop. For this legendary train trip, we highly recommend checking our Asia Regional or Global eSIM plans to stay connected across all three countries.
