What is an eSIM and how does it work?
An eSIM (embedded SIM) is a digital SIM profile built into your phone’s hardware. After purchasing, you receive a QR code; scanning it installs a data plan on a second line. No physical SIM swapping is needed.
Which devices support eSIM?
Most flagship phones released since 2019 support eSIM: iPhone XS/XR or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer (varies by region), plus many iPad models. Check your device’s settings for "Add eSIM" to confirm.
When should I install my eSIM?
Install it at home over Wi-Fi before departure. Most plans only start counting their validity days once the phone connects to a supported network at your destination.
Can I keep my WhatsApp / original number?
Yes. A travel eSIM provides data only — your primary SIM stays active for calls, SMS and apps like WhatsApp, Zalo or KakaoTalk.
Can I share my eSIM data (hotspot)?
In most cases yes — the major providers listed here allow tethering. Some unlimited day passes restrict hotspot speed; always check the plan details at checkout.
Are prices on this site final?
We show the provider’s public USD price and apply verified promotions when detected. Taxes may be added at checkout depending on your billing country. The checkout page always shows the final amount.
