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.
