What is T-Mobile?

T-Mobile is a subsidiary of German telecommunications company Deutsche Telekom AG providing wireless voice, messaging and data services to customers in dozens of countries. 

In the US, the company has more than 104 million customers and became the second largest telecommunications company behind Verizon after its $26 billion merger with Sprint in 2018. 

How many people are affected by the hack?

T-Mobile released a statement last week confirming that the names, dates of birth, social security numbers, driver’s licenses, phone numbers, as well as IMEI and IMSI information for about 7.8 million customers had been stolen in the breach.

Another 40 million former or prospective customers had their names, dates of birth, social security numbers and driver’s licenses leaked. 

More than 5 million “current postpaid customer accounts” also had information like names, addresses, date of births, phone numbers, IMEIs and IMSIs illegally accessed. 

T-Mobile said another 667,000 accounts of former T- Mobile customers had their information stolen alongside a group of 850,000 active T-Mobile prepaid customers, whose names, phone numbers and account PINs were exposed. 

The names of 52,000 people with Metro by T-Mobile accounts may also have been accessed, according to T-Mobile.
