What an eSIM is, how to check your phone supports it, when to install it and how to avoid surprises.
What is an eSIM?
An eSIM is a digital SIM built into your phone. You buy a data plan online, scan a QR code or tap an install link, and your phone gets local internet — no plastic card needed.
Check your phone first
Most recent iPhones, Google Pixels and Samsung Galaxy phones support eSIM, but some models and some phones sold in certain countries don't. Your phone also needs to be carrier-unlocked.
Install before you fly
Install the eSIM at home on Wi-Fi, then switch it on when you land. Keep your normal SIM for calls and SMS codes, and set the eSIM as the line for mobile data.
Pick the right plan
Data-only plans cover maps, messaging and browsing. Choose by days and gigabytes; regional plans are handy when one trip covers several countries.
