Find out instantly if your smartphone has the hardware to support digital eSIM profiles and a carrier-grade secure UK second number.
An EID (Embedded Identity Document) is the unique ID of the built-in microchip inside your phone. Checking for it is the most reliable way to confirm eSIM capability:
*#06#**.Go to **Settings > Mobile Service** (or Cellular). If you see **"Add eSIM"** or **"Add Mobile Plan"**, your iPhone is compatible.
Go to **Settings > Connections** (or Network & Internet) > **SIM Manager**. If you see **"Add eSIM"** or **"Add Mobile Plan"**, your Android is compatible.
This list is updated continuously. Most smartphones released from 2019 onwards have eSIM capability built-in as standard.
Even if your smartphone supports eSIM hardware, **it must be carrier-unlocked** (not bound to a contract lock with networks like EE, O2, Vodafone, or Three) to activate a SecondSim digital plan.
If you purchased your phone directly on a monthly contract, contact your network carrier first to request a device unlock. It is typically processed within a few hours for free.
