T-Mobile is notifying some customers about a recent security breach

In a statement on its website, T-Mobile said it uncovered the hack on Monday.

According to the full statement being sent to those unlucky enough to be included, more sensitive information like social security numbers and credit card details were not included in the breach.

The breach was spotted on 20 August by the firm's cyber-security team, it said, and was plugged the same day.

T-Mobile has reported a security incident which may have led to the exposure of personal data belonging to approximately two million customers.

Affected customers can expect to receive a text from the carrier, if they haven't already. Affecting customers in the United States, the hack is not the first time T-Mobile customers have been put at risk; a couple of years ago company data was leaked via Experian. Doing some quick math, three percent of 77 million is 2.31 million. Those with additional concerns are encouraged to contact customer care by dialing 611, using two-way messaging in the T-Mobile app, online at or via iMessage through Apple Business Chat. The exposed data includes names, billing zip code, phone number, email address, account number and account type, which would be enough for hackers to launch successful phishing attacks. But data breaches and new kinds of cellular fraud are gradually making the practice less effective, Guido says. "We truly regret that this incident occurred and are so sorry for any inconvenience this has caused".
