Quick answers to common eSIM questions.
What is eSIM? +
An eSIM is a digital SIM card built into your device. Carrier profiles are downloaded wirelessly via QR code. For European travel, this means instant connectivity without airport SIM kiosks.
How do I check if my phone supports eSIM? +
iPhone: Settings → Cellular → look for "Add eSIM". Samsung: Settings → Connections → SIM Manager → "Add Mobile Plan". Check our
device list for a full reference.
Does my device need to be carrier-unlocked? +
Yes. Contact your carrier to request an unlock — most do this free of charge after the contract period ends.
Can I keep my home number while using a travel eSIM? +
Yes — via Dual SIM. Keep your home SIM for calls/texts; use the travel eSIM for data. Configure in cellular settings.
When should I install the eSIM? +
Before departure, at home, on WiFi. This ensures immediate connectivity upon landing and avoids airport troubleshooting.
Does one eSIM cover all of Europe? +
Many plans cover 30–50 countries. Always verify the exact country list, especially for Switzerland, Norway, Iceland, and the UK (non-EU).
