BASICS
What Is an eSIM?
An eSIM is basically a SIM card without the card: you download a plan directly to your device via QR code or app, with no physical chip to swap. Your main SIM stays active while you add affordable mobile data for your trip.
METHODOLOGY
How I Test eSIMs
Every plan is activated and used in real life, not rated from a spec sheet. Four criteria determine the result:
Coverage & Network Quality
How reliably a plan actually works where you are, measured in real-world use, not in a lab.
Activation & Setup
From QR code to first connection: how fast and hassle-free is setup?
Price, Validity & Throttling
Price per GB, validity period, and hidden data caps.
Support & Reliability
Response time and support tested in a real-world case.
