Question 1

What is an eSIM and how does it work for international travel?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM card built into your smartphone. It allows you to activate a cellular data plan without having to use a physical SIM card. For travel, you simply scan a QR code sent to your email to install a local data profile before you land, keeping you instantly connected.

Question 2

Which smartphones are compatible with eSIM profiles?

Accepted Answer

Most flagship Apple iPhones (iPhone XR or newer), Samsung Galaxy series (S20 or newer), and Google Pixel devices support eSIM. Please note that iPhones manufactured in Mainland China, Hong Kong, and Macao with dual-physical nano-SIM slots are generally not eSIM compatible. Always verify with our eSIM Compatibility Checker tool before purchase.

Question 3

When should I install and activate my travel eSIM?

Accepted Answer

We recommend installing your eSIM profile one day before departure using your stable home Wi-Fi or cellular connection, or at the departure airport. For most plans, the validity period and data billing starts only when the eSIM connects to a supported network at your destination.
