This specific Triply plan is your group's ticket to connectivity exclusively within Mongolia. The legendary Trans-Mongolian Railway journey is an incredible experience, but it does cross international borders. Once your train rolls into Russia (Siberia) or China (Inner Mongolia), your Triply connection for Mongolia will pause. To keep your whole crew online throughout this epic multi-country train ride, we suggest looking into our regional eSIM options that cover all the nations on your itinerary. That way, you won't miss a beat!
