Frequently Asked Questions

An eSIM (embedded SIM) is a digital SIM card permanently built into your device. Unlike a physical SIM card that you insert and remove, an eSIM is programmed remotely through a QR code or app, allowing you to switch between mobile network providers without ever handling a physical card.

Not exactly. An eSIM is a physical chip embedded in your device — it's just programmable. A "virtual SIM" is a broader term sometimes used for software-based solutions. eSIM is the industry-standard hardware implementation defined by the GSMA.

No. Travel eSIMs are designed to work alongside your existing plan. Your home SIM (physical or eSIM) remains active for calls and SMS, while the travel eSIM handles data in Europe. You simply switch which line handles data in your device settings.

It depends on the provider. Some eSIM plans allow you to top up data or extend validity. Others are single-use. The eSIM profile itself usually remains installed on your device, so for future trips you may only need to purchase a new data package rather than reinstalling the profile.

Yes. eSIM profiles are stored in a tamper-resistant secure element within your device. The remote provisioning process uses end-to-end encryption. eSIM is actually more secure than physical SIM cards in some respects, as it cannot be physically stolen or swapped without your knowledge.

Install the eSIM profile (scan the QR code) before your trip while on home Wi-Fi. However, don't enable it as your active data line until you arrive in Europe — otherwise your plan's validity period may start counting down before you need it.

Ensure you have a stable internet connection. Clean your camera lens. If scanning from a screen, try increasing brightness or printing the QR code. Most providers also offer a manual activation code as an alternative to QR scanning.

No, you need an internet connection to download the eSIM profile. This can be your home Wi-Fi, airport Wi-Fi, or a mobile data connection from another device. This is why activating before travel is strongly recommended.

The entire process — from scanning the QR code to having an active connection — typically takes 2 to 5 minutes on a good Wi-Fi connection. The profile download itself is usually complete within 30 seconds.

On iPhone: Settings → General → About → look for "Digital SIM" or an EID number. On Android: Settings → About Phone → look for an EID. You can also check your device manufacturer's specifications page for your exact model.

Yes, your device must be carrier-unlocked to use an eSIM from a different provider. Most phones are unlocked after their contract period. Contact your carrier to request an unlock if needed — this is usually free and done remotely.

Many modern tablets (iPad, Samsung Galaxy Tab) and smartwatches (Apple Watch, Samsung Galaxy Watch) support eSIM. However, travel eSIM plans are primarily designed for smartphones. Check with your specific provider whether their plans support tablets or wearables.

Pan-European eSIM plans typically cover all 27 EU member states. Always verify the coverage map of your specific plan before purchasing, as coverage can vary between providers. Non-EU European countries like Switzerland, Norway, and the UK may require separate coverage.

At sea, ships use maritime satellite networks rather than land-based mobile networks. Your eSIM will not work on the open ocean. However, when your ship is in port or close to shore, you should be able to connect to local land-based networks.

Most travel eSIM plans are data-only. For voice calls, you can use VoIP apps (WhatsApp, FaceTime, Skype, Google Meet) over your eSIM data connection. Your home SIM remains active for traditional calls. Some premium eSIM plans do include voice minutes — check your plan details.

When your data allowance is exhausted, your connection either stops or is throttled to a very slow speed (depending on the plan). Most providers allow you to purchase additional data top-ups through their app or website. Always monitor your usage through your device's data tracking settings.

First, ensure the eSIM is set as your active data line in settings. Toggle airplane mode on and off. Try manually selecting a network operator. Restart your device. If the issue persists, contact your eSIM provider's support — they can often resolve activation issues remotely.

Contact your eSIM provider directly. Most providers can reissue a QR code after verifying your identity and purchase details. This is why it's recommended to save your original QR code as a screenshot in a secure location like cloud storage.

Check if you've exceeded your high-speed data allowance. Verify you're connected to 4G/LTE rather than 3G. Try manually selecting a different network operator in your cellular settings. Move to a location with better signal. Restart your device to force a fresh network connection.

Yes, factory resets typically erase all eSIM profiles. Before performing a factory reset, note your eSIM provider details and contact them afterward to request a new QR code for reinstallation. Some providers allow this free of charge.

Most travel eSIM plans include hotspot/tethering functionality, but always verify before purchasing. Hotspot usage consumes data from your plan's allowance. For heavy laptop use, consider purchasing a plan with a larger data allowance or one specifically designed for hotspot use.
