Voxi, a mobile virtual network operator (MVNO) that uses Vodafone’s network, now offers eSIMs for new and existing customers on SIM-only plans. These are digital SIMs that are built into phones, making it easier and faster to switch between networks than if your device has a physical SIM card. Voxi says you can get connected in under 10 minutes – see www.voxi.co.uk/esim.
