Google is in the process of notifying Google Fi customers that their data was stolen as part of T-Mobile’s breach earlier this month.
On January 5, a hacker hacked into T-Mobile’s network and stole data from 37 million customer accounts. Google Fi uses T-Mobile’s network for the majority of its connections, so it appears the hacker was also able to access Google Fi’s customer data.
The Google Fi team emailed customers yesterday notifying them “there has been suspicious activity related to a third-party system containing a limited amount of Google Fi customer data”. Stolen information includes:
-
phone number
-
SIM card serial number
-
when an account has been activated
-
account status (active, inactive)
-
mobile service plan details (e.g. unlimited texting, international roaming)
No Google systems were accessed directly during the data breach and no customer personal information was taken beyond what is noted above.
Google made a point of emphasizing in the email that the data stolen “does not contain your name, date of birth, email address, payment card information, social security number or tax IDs, driver’s license or other form of government identification, or financial account information, passwords or PINs that you may use for Google Fi, or the content of any text or call.”

Any customer receiving this email from Google Fi should be aware of phishing attempts. The hacker got just enough information for someone to sound convincing enough in a call or email.
