Digital SIMs — which networks, which devices, how to activate.
Ask us about this →An eSIM (embedded SIM) is a digital SIM built directly into your device — no physical plastic card needed. Activate by scanning a QR code or using an app. Takes about 10 minutes. First launched in UK by major networks around 2018–2019, now standard across all operators.
