The bright orange 'Black Friday 4X DATA' tag and the unusual imagery of brains in jars.

The ad opens with a black background and a white diagonal stripe on the left. A bright orange tag with 'Black Friday 4X DATA' is visible. Next to it, a graphic shows a SIM card with '25GB 100 GB FOR £12'. Below this, large white text reads '+ unlimited data for social media'. The right side of the screen shows a dimly lit laboratory setting with two glass cylinders. Each cylinder contains a human brain suspended in liquid, illuminated by green and pink lights respectively. Two smartphones are placed on stands in front of the cylinders. The scene is dark and slightly eerie, contrasting with the bright promotional text.
