Will I have HotelESIM signal in the Paris Metro and on TGV trains?

Yes, you can expect excellent connectivity with your HotelESIM even while exploring below ground or traveling at high speeds. France boasts a very advanced mobile infrastructure, ensuring strong 4G/LTE (and often 5G) coverage. You'll find reliable signal within Paris Metro stations and most tunnels, perfect for planning your next stop or checking hotel directions. Similarly, on the high-speed TGV trains connecting major cities, your HotelESIM will provide a stable connection for the majority of your journey, allowing you to work, stream, or relax with continuous internet access.
