Broadcasting on 93.1 FM, XHEI is owned by Grupo Radiorama and is known as Romántica with a romantic music format.

XEEI-AM 1070 signed on in 1985 as Radiorama's first affiliated station in San Luis Potosí, known as Radio Servicio Social and owned by a concessionaire of the same name; its concession was awarded March 12, 1986.

MG Radio once more began operating XEEI in January 2008, giving it the Ke Buena grupera format.

On December 29 of that year, XEEI gained its FM counterpart, XHEI-FM 93.1, and on January 31, 2011, the new AM-FM combo began stunting to a new format, "Antena Radio 93.1" (stylized as ANT:NA), with rock and alternative music.

In July 2012, as a result of XEWA-AM/XHEWA-FM's format change to Los 40 Principales, XHEI began airing select W Radio programs until December 2016.
