Everything you need to know about eSIM technology before your trip
An eSIM (embedded SIM) is a digital chip built directly into your phone. Unlike traditional SIM cards that you need to physically insert, an eSIM is activated digitally by scanning a QR code. No store visits, no chip cutting, no waiting for shipping.
Scan a QR, activate the plan, and you're connected in minutes.
Get your eSIM by email and activate it by scanning the QR. No waiting, no shipping.
Keep your personal number active while using local data with the eSIM. Perfect for WhatsApp.
Avoid surprise international roaming charges. Pay a fixed price before you travel.
Cannot be physically extracted or cloned. Your connection is protected.
No plastic, no packaging, no waste. 100% digital.
Switch plans or providers without needing to change chips.
Modern devices can store multiple eSIM profiles, though only one or two can be active simultaneously.

To use an eSIM, your phone must be unlocked — meaning it's not tied exclusively to one carrier (like AT&T, T-Mobile, Verizon, etc.). An unlocked phone can use SIMs or eSIMs from any provider.
iPhone
Settings → General → About → look for "No SIM restrictions"
Android

Contact your carrier
Call your current carrier and ask if your phone is unlocked. If not, request an unlock.
