In February 2018, the singer (then known under her original name, Aitana Ocaña), was proclaimed the second finalist of the Spanish talent show Operación Triunfo, in its ninth edition.^[1] After that achievement, the Barcelona-native singer began working on what would be her first album.

On 25 October, the singer visited the Spanish talk show El Hormiguero 3.0. where she unveiled the name of her first project.^[6] It would be called Tráiler and, according to her, "it's like a two-piece album. The time interval between the two EPs will be little more than two-three months because I think that today we devour more than we consume and, for that reason, I like the idea of doing everything little by little. The first part will be released at the end of November. It has a strange name, after a lot of thought, I decided that it was called Tráiler because it is like an appetizer of only six songs of everything that is to come later."^[7][8]

A few weeks later, on 13 November, the singer unveiled via her social media the cover of the EP, which was photographed by Valero Rioja. On 19 November, the EP's track list was released online.^[9] Two days later, the official remix of "Teléfono" was released on digital music platforms. It features Venezuelan personality Lele Pons.

This reached the first position in the PROMUSICAE sales list and remained there six consecutive weeks. The music video for the song was premiered simultaneously with the song.^[12]

In November 2018 she announced that the EP's second single would be "Vas a quedarte".^[13] The song went on to become Aitana's third number-one single in Spain, additionally being certified gold.
