The countdown timer and the image of a pigeon with 'data boooost' effects.

The ad opens with a countdown from 10 to 1, featuring a pigeon sitting on a ledge. As the countdown progresses, the pigeon appears to be 'data boosting' with pink and white energy effects. The final seconds show the pigeon engulfed in pink smoke, transitioning to a smartphone screen displaying '£10' and '75 GB'. The ad concludes with the giffgaff logo and tagline.
