The ad documents a real-life aspiring musician called Josh and his quest to form a superband.
Josh appeared in the first part of the campaign in September, in which real people were stopped in the street and asked what they would do with free texts for life. Josh said he would set up a superband, so T-Mobile challenged him to set up his band.
In the first ad, Josh recruits participants by travelling through London on an open-top bus. A further instalment is due to launch at the end of November.
The campaign also uses Twitter, YouTube and MySpace, as well as radio and outdoor ads.
The campaign, created by Saatchi & Saatchi London, is designed to support T-Mobile's deal offering unlimited free texts and mobile internet for life.
