Frequently Asked Questions

Everything you need to know about eSIM for European travel.

Getting Started

What is eSIM and how is it different from a regular SIM? +

An eSIM is a digital SIM card built into your device. Unlike a physical SIM you insert and remove, an eSIM is soldered to the motherboard and carrier profiles are downloaded digitally. For travelers, this means instant activation online without visiting a store or airport kiosk.

How do I know if my phone supports eSIM? +

Check Settings → Cellular (iPhone) or Settings → Connections → SIM Manager (Samsung). If you see an "Add eSIM" or "Add Cellular Plan" option, your device supports eSIM. See our device compatibility page for a full list.

Do I need to unlock my phone first? +

Yes — your device must be carrier-unlocked to use a third-party eSIM plan. Contact your carrier to request an unlock. Most carriers unlock devices for free after your contract period ends or upon request.

Can I keep my home number while using a travel eSIM? +

Yes — use Dual SIM. Keep your home SIM or eSIM active for calls and texts, and use your travel eSIM for data. Configure in cellular settings: set the travel eSIM as default data and your home SIM for voice/SMS.

Activation & Setup

When should I install the eSIM? +

Install the eSIM profile at home on WiFi before departure. This ensures you have connectivity immediately upon landing. Activation (when your data plan starts) depends on your plan — some start on installation, others on first data use.

Do I need WiFi to install an eSIM? +

Yes — eSIM profiles download over the internet. Use WiFi or existing cellular data. We strongly recommend installing on home WiFi before departure to avoid issues.

The QR code won't scan. What do I do? +

Ensure good lighting and increase screen brightness. Clean your camera lens. Use the manual entry option — your provider's email should include the SM-DP+ address and activation code for manual input.

Travel & Coverage

Does one eSIM plan cover all of Europe? +

Many providers offer regional European plans covering 30-50+ countries. Always check the specific country list, especially for non-EU countries like Switzerland, Norway, Iceland, and the UK.

Can I use eSIM as a mobile hotspot? +

Most plans allow hotspot/tethering. Check your plan's terms. Note that hotspot uses data much faster — a video call uses approximately 1-2GB per hour. Set a data warning threshold.

What happens when my data runs out? +

Depending on your plan: data may stop entirely, speeds may be throttled to 64-128 kbps, or you may be able to purchase a top-up. Check your plan's terms before departure.

What if I accidentally delete my eSIM? +

The original QR code is now invalid. Contact your provider immediately — most can reissue a new QR code for the same plan. Always save a screenshot of your QR code before scanning as a precaution.
