"We have introduced a Wi-Fi service at our cemetery complex after requests from users of the facility," municipal sources told The Local.
Granada's council switched on the password-free wireless internet service on Monday.
As a result, mourners in San José's vigil rooms will now be able to use their mobile telephones, computers and other electronic devices while they watch over their loved ones.
The town hall told The Local that a number of users of the complex, which includes a crematorium and a chapel as well as a cemetery, had asked for Wi-Fi access.
"This makes Granada a pioneer in Spain," said María Francés, the spokeswoman for Emucesa, the public company which runs the complex, in a presentation to introduce the Wi-Fi service on Monday.
During the presentation, the town hall added that the introduction of Wi-Fi at the San José site would also improve the cemetery's telephone service.
Granada's mayor José Torres Hurtado said the council had been unable to repair the cemetery's phone service in the past because it was too close to the Alhambra palace.
The city's town hall was unable to confirm whether there had been any objection to the plans.
