Simple answers to common eSIM questions. No jargon!
What exactly is an eSIM? +
An eSIM is a digital SIM card built into your phone. Instead of inserting a plastic card, you download carrier plans wirelessly via a QR code. For travellers, this means instant connectivity without visiting a store.
How do I know if my phone supports eSIM? +
On iPhone: Settings → Cellular → look for "Add eSIM". On Samsung: Settings → Connections → SIM Manager → "Add Mobile Plan". Check our
device list for a complete reference.
Do I need to unlock my phone first? +
Yes! Your phone must be "carrier-unlocked" to use a travel eSIM. Contact your home carrier and ask them to unlock your device. Most do this for free after your contract ends.
Can I still use my home number? +
Yes! Use Dual SIM: keep your home SIM for calls and texts, use your travel eSIM for data. Set up in your phone's cellular settings.
When should I install the eSIM? +
Install it at home before you travel, while connected to WiFi. This way you'll have instant connectivity the moment you land in Europe.
What if I accidentally delete my eSIM? +
Contact your eSIM provider immediately — they can usually reissue a new QR code. Tip: always save a screenshot of your QR code before scanning it!
My eSIM isn't working — what do I do? +
Try these steps: 1) Toggle airplane mode on/off. 2) Check that your eSIM is set as the data line. 3) Enable data roaming. 4) Try selecting the network manually. 5) Restart your phone. Still stuck? Contact your eSIM provider.
