Will I maintain an internet signal on Spain's high-speed trains (Renfe/Iryo) with eSIMAdventures?

Yes, for the vast majority of your journey on Spain's impressive high-speed train network (Renfe/Iryo), your eSIMAdventures signal will be strong and stable. Spain boasts an excellent mobile infrastructure that largely follows these routes. You can expect consistent 4G/5G connectivity for streaming, navigation, and staying connected between major cities like Madrid and Seville. However, be prepared for brief signal interruptions when trains pass through longer tunnels, especially in mountainous or rural areas. These are typically short-lived, and connectivity usually resumes swiftly once out in the open.
