If you bought any flagship phone in the last 3–4 years, you’re already carrying an eSIM — even if you’ve never activated it. Apple removed the physical SIM tray completely in the US starting with iPhone 14 (2022), Google Pixel 8/9 and Samsung Galaxy S24/S25 series are going eSIM-first in most markets, and by the end of 2025 more than 65% of new smartphones worldwide will be eSIM-only or hybrid.
So let’s settle it once and for all — what exactly is an eSIM in 2025, and why should you care?
What is an eSIM?
An eSIM (embedded SIM) is a programmable digital SIM that is soldered directly onto your phone’s motherboard. No plastic card, no tray, no tiny tool — you just download a carrier profile (usually by scanning a QR code) and you’re instantly connected.
Think of it as the “App Store for mobile plans” — install, switch, or delete plans in seconds from anywhere.
