What is eSIM? +
An eSIM is a digital SIM card embedded in your device. Instead of a physical card, carrier profiles are downloaded digitally. For travelers, this means instant connectivity without visiting a store or airport kiosk.
How do I check if my phone supports eSIM? +
iPhone: Settings → Cellular → Add eSIM (if option exists, eSIM is supported). Samsung: Settings → Connections → SIM Manager → Add Mobile Plan. See our
device database for a complete list.
Do I need to unlock my phone? +
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.
Can I keep my home number while using a travel eSIM? +
Yes — use Dual SIM. Keep your home SIM/eSIM for calls and texts, use your travel eSIM for data. Configure in cellular settings.
When should I install the eSIM? +
Install at home on WiFi before departure. This ensures immediate connectivity upon landing and avoids troubleshooting at the airport.
Does one eSIM cover all of Europe? +
Many providers offer regional plans covering 30-50+ countries. Always verify the specific country list, especially for Switzerland, Norway, Iceland, and the UK (not EU members).
Can I use eSIM as a hotspot? +
Most plans allow hotspot/tethering. Check your plan's terms. Hotspot uses data quickly — a video call uses approximately 1-2GB per hour.
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. Always save a QR code screenshot before scanning.
How many eSIM profiles can I store? +
iPhone 15/16 series: up to 8 profiles. Most Android devices: 5-10 profiles. Only 1-2 can be active simultaneously, but stored profiles can be switched without re-downloading.
No service after activation — what do I do? +
Toggle airplane mode → Verify eSIM is set as data line → Enable data roaming → Try manual network selection → Restart device → Contact provider if persistent.
