Will I have signal in the Paris Metro and on French high-speed trains?

Yes, France boasts excellent digital infrastructure. With eSIM Trails, you can expect reliable 4G/LTE (and often 5G) coverage even deep within the Paris Metro system, including stations and tunnels. On high-speed trains like the TGV, connectivity is generally strong throughout the journey, though very brief interruptions might occur in remote, mountainous sections. Our focus on robust networks ensures you stay connected whether you're navigating urban undergrounds or speeding across the countryside.
