Phonebox 1 is a mission in Grand Theft Auto: London 1969 level 1, Boys Will Be Thieves, given to the Protagonist by the London Mob. It is available from the phonebox in northeast Chelsea and is the only mission available in the level itself.
The mission begins with the protagonist being told that if they want work, then to go to the phonebox in northeast Chelsea. After answering the phone, the protagonist will be told that the Crisp Twins, Albert and Archie, want a Mod Scooter for their mother. The protagonist will then have to go to central Chelsea, steal the parked scooter and then take it back to Harold Cartwright's place in southeast Soho (although the dialogue says Mile End). After delivering the scooter, the protagonist will then have to meet Harold in the alleyway next to his place in order to complete the mission and the level.
The player will be awarded a +1 score multiplier for completing the mission.
