eSIM Setup & Activation

Welcome to the Future of SIM Technology

Written by Olly Levine

With CyberTel, you can activate your plan instantly using eSIM technology — no physical SIM card, no waiting for delivery. Just scan, activate, and connect.

Depending on your plan, you'll have one or two eSIM profiles:

  • UK SIM/eSIM — your main line for calls, texts, and UK data. Included on every plan.

  • Global eSIM — worldwide data coverage across 207 destinations. Included on Globetrotter, Aero, Forces, Sail, and RailReach plans.

  • ✅ Connect to WiFi — you'll need internet for activation

  • ✅ Have your QR code ready — it's emailed to you after checkout

  • ✅ For dual eSIM plans, decide which slot you want to assign to each profile
