Reliable connectivity depends on the device, route, selected plan and local network conditions, so check each of these before travelling.
We created this guide to help you stay connected in Spain, with practical advice on setup, coverage, data use and troubleshooting.
Our travel eSIM plans are data-only. They provide internet for maps, messages and supported calling apps, but no local number, ordinary voice minutes or SMS.
Quick answer: Mobile data can work on parts of the journey, but continuous service should not be expected. Download tickets, route information, maps and essential entertainment before boarding.

Why Train Coverage Changes
Speed, tunnels, rural areas, carriage construction, congestion and network handovers affect onboard Wi-Fi, tunnels, rural coverage, stations, tickets, maps and offline preparation. Signal can change quickly while moving.
Use a reversible check first: confirm the plan or service requirement, observe the current status and change one setting at a time. This approach is especially important for onboard Wi-Fi, tunnels, rural coverage, stations, tickets, maps and offline preparation, where replacing the profile or resetting the phone would remove useful diagnostic evidence.
Prepare before Boarding
Save the train number, station names, accommodation address and offline maps. Do not rely on a connection for the only copy of a ticket.
The decision should account for onboard Wi-Fi, tunnels, rural coverage, stations, tickets, maps and offline preparation. Check current product and device information at the time of use because network access, hotspot support, 5G, compatibility and retail conditions depend on the selected plan, exact model, region and local coverage.
Use Data Safely on the Journey
Avoid sensitive work on unverified public Wi-Fi, control video and cloud backup, and keep devices charged with safe approved equipment.
For Spain, prepare the information that would be hardest to recover during an outage: the route, booking reference, address, support details or device instructions. Offline preparation matters most when the itinerary includes onboard Wi-Fi, tunnels, rural coverage, stations, tickets, maps and offline preparation.
Select the Correct Data Line
Choose the travel eSIM for Mobile Data, enable Data Roaming on that line and disable automatic switching. Our data-only travel eSIM supplies internet but does not provide ordinary voice calls or SMS.

Understand Moving-Network Limitations
Trains, tunnels, ferries, rural roads, buildings and congestion can interrupt service. Save the only copy of a ticket or address outside the app and allow route instructions to load before movement.

Check current product and device information at the time of use because network access, hotspot support, 5G, compatibility and retail conditions depend on the selected plan, exact model, region and local coverage.
Control App Data Use
Text and basic navigation are lighter than video, media backup and internet calls. Disable automatic downloads and monitor usage by app when the allowance is limited.

Offline preparation matters most when the itinerary includes onboard Wi-Fi, tunnels, rural coverage, stations, tickets, maps and offline preparation.
Troubleshoot without Deleting the eSIM
Test an ordinary website, confirm the active data line and refresh registration with Airplane Mode. If manual APN entry is required, use data.esim. Keep the profile installed unless Support gives specific removal instructions.
