The SCJN puts a stop to telephone companies
Nine ministers said ‘enough’. The full Supreme Court has just slammed the table against mobile phone companies. Their fault is clear: they will have to check who you are when you ask to change your SIM card. No lazy procedures.
Minister Loretta Ortiz Ahlf took the case and made it clear: changing a SIM without rigorous verifications is illegal. Spot. This practice not only violates the confidentiality of your communications, but also opens the door to bank fraud, disclosure of personal data and improper access.
The case that changed everything
It all started with a woman in Mexico City. He linked his number to apps, social networks and banking services. When he left the service, hell began: password change notifications, banking attempts… and to top it all off, his contacts received intimate content from him.
When he complained, they dropped the bomb: someone had requested the replacement of his SIM in Chihuahua. Verifications? Zero.
“It was the woman’s decision to link her phone number to different apps”
>
“The intimate content was taken by her”
>
“It did not react in a timely manner to the alerts”
That was AT&T’s defense. They denied all responsibility. Before reaching the Court, even a judge had concluded that there were no elements to prove the company’s negligence.
But the ministers saw what others did not want to see: digital violence.
The plenary session not only recognized the moral damage, but also ordered comprehensive reparation and asked to judge with a gender perspective, “without stereotypes or revictimization.” Now telephone companies will have to implement strict protocols: in-person identification, information collation, security questions.
A ruling that comes late for many, but that marks a before and after. Companies will no longer be able to wash their hands when someone steals your digital identity by changing a SIM as if it were nothing.
