Frequently Asked Questions
What is an eSIM and how does it work?
An eSIM (embedded SIM) is a digital SIM profile built directly into your smartphone hardware. You simply scan a QR code to activate mobile data instantly without swapping physical plastic cards.
Can I keep my WhatsApp and original phone number?
Yes. Travel eSIMs only handle mobile data. Your primary phone number remains active for SMS, phone calls, and messaging apps like WhatsApp or Telegram.
When should I install my eSIM before traveling?
We recommend installing your eSIM before departure using Wi-Fi at home or the airport. The validity period usually begins only when you connect to a supported local network at your destination.
