Frequently Asked Questions

An eSIM (embedded SIM) is a digital SIM card built into your device. You activate a carrier plan by scanning a QR code or using an app, without needing a physical card. Multiple profiles can be stored, though typically only one is active at a time.

On iPhone: Settings → General → About → look for EID. On Android: Settings → Network & Internet → SIM cards. An EID number confirms eSIM hardware support. Note that some devices have eSIM hardware but with functionality disabled by the carrier.

Yes, if your device supports dual-SIM. Most modern smartphones allow simultaneous use of a physical SIM and eSIM. Configure your home SIM for calls/SMS and the eSIM for data while traveling.

Purchase a plan from a provider, receive a QR code, scan it through your device's eSIM settings, and follow the prompts. Installation requires WiFi or cellular and takes 1–5 minutes. Some providers offer app-based installation.

Transfer policies vary by provider. Some allow transfers through their app; others require a new plan purchase. Verify the provider's transfer policy before deleting a profile.

EU regulations allow travelers from EU member states to use their home plan across EU countries at domestic prices, subject to fair-use policies. Travelers from outside the EU are not covered and should evaluate alternatives.

Fair-use policies prevent permanent roaming. Carriers can apply surcharges if roaming usage significantly exceeds domestic usage over a four-month period. For genuine travelers, fair-use limits are rarely a practical concern.

No. UK travelers are no longer protected by EU roaming regulations. UK carriers may charge roaming fees for EU travel. UK travelers should check their carrier's current EU roaming policy and consider eSIM alternatives.

Light users: 500MB–1GB/day. Moderate users: 2–3GB/day. Heavy users (video calls, streaming): 5GB+/day. For a two-week trip, 10–15GB covers most travelers. Remote workers should plan for 90–240GB/month.

Before departure is strongly recommended. This ensures connectivity immediately upon arrival for navigation and transportation apps. Some plans require WiFi for activation, making pre-departure installation essential.

Throttling reduces connection speed after a data quota. Many "unlimited" plans throttle to 128Kbps after a high-speed quota. At this speed, video calls are impossible. Always check the high-speed quota and post-throttle speed.

High-speed rail corridors generally have good mobile coverage. Signal drops in tunnels. Many high-speed trains offer onboard WiFi. Overnight trains and regional services may have limited connectivity.

Toggle airplane mode off and on. Verify data roaming is enabled and the correct eSIM is selected. If the issue persists, contact provider support. Most airports and stations have free WiFi as a backup.

Most plans allow hotspot/tethering, but some restrict it or apply separate data limits. Check plan terms explicitly before assuming hotspot is included.

For most travel use cases, 4G LTE provides adequate speeds. 5G benefits users who regularly transfer large files or conduct frequent video conferences. 5G availability remains concentrated in major European cities.

Lisbon, Tallinn, Berlin, Amsterdam, and Barcelona consistently rank highly for remote work infrastructure, combining strong connectivity with active co-working ecosystems and digital nomad communities.

Insert a SIM from a different carrier. If it connects, the phone is unlocked. Alternatively, contact your carrier directly. In many markets, carriers must unlock devices after the contract period ends.
