For optimal performance with DataESIM in the United Kingdom, your device must be eSIM-compatible and factory unlocked. Most flagship smartphones from recent generations support eSIM technology, including iPhone XS and all subsequent models, Samsung Galaxy S20 series and newer, and Google Pixel 4 and later iterations. We recommend verifying your specific device's eSIM capability and ensuring it is not carrier-locked to guarantee a smooth provisioning experience and access to the high-speed networks of EE or O2.
