Frequently Asked Questions

Everything you need to know about setting up and using your travel eSIM.

What is an eSIM and how does it work?
An eSIM (embedded SIM) is a digital microchip built into your smartphone that replaces physical plastic SIM cards. You download your mobile data plan over the internet using 1-click automatic setup or by scanning a QR code, giving you high-speed data without visiting a carrier shop.
What is 1-Click Fast Install?
If you purchase on your phone or open your eSIM details page in 'My eSIMs' on Safari or Chrome, you don't need a second device to scan a QR code. Simply tap 'Install on iPhone' or 'Install on Android' to trigger your phone's native cellular setup modal with 1 tap.
How fast can I get connected?
You can be online in under 2 minutes. After checkout, your eSIM profile is provisioned immediately. Install it with 1-click or scan the QR code before you board your flight, and your phone will connect to 5G automatically the moment you land.
Can I keep my WhatsApp and regular phone number active?
Yes! Your smartphone supports Dual SIM mode. Keep your primary physical SIM active for incoming phone calls, SMS, and banking 2FA codes. Your WhatsApp account stays linked to your normal number while eSIMFlux handles high-speed travel data.
When does my data plan validity begin?
For most travel plans, validity only begins counting down when your eSIM connects to a supported cellular network at your destination country. You can safely install your eSIM prior to departure.
Do I need Wi-Fi while installing?
Yes. Your device requires an active Wi-Fi or cellular data connection to download and authenticate the cryptographic profile from the GSMA eSIM server.
